Making Your own Orgonite Generator http://www.science-lessons.ca/making-orgonite-generator/ http://www.science-lessons.ca/making-orgonite-generator/#respond Wed, 29 Jan 2014 03:49:32 +0000 http://www.science-lessons.ca/blog/?p=1751 First, a bit about What is Orgone?  And What is an Orgonite Generator?  Orgone energy is a hypothetical universal life force that was first known coined by a 1930’s scientist named Wilhelm Reich.  An Orgonite Generator is a homemade device using a container of inorganic and organic materials, that is designed to turn negative energy into positive uplifting energy, in general.  http://www.orgonite.info/what-is-orgonite.html.   Reich was experimenting with collecting different forms of energy to make positive generators.  In its final conception, developed by Reich’s student Charles Kelly after Reich, Orgone was conceived as the anti-entropic principle of the universe, a creative substratum in all of nature comparable to Mesmer’s animal magnetism. Orgone is regarded by the National Center for Complementary and Alternative Medicine as a type of “putative energy. There is no empirical support for the concept of orgone in medicine or the physical sciences, and research into the concept ceased with the end of the Institute.  www.orgonite.info  http://en.wikipedia.org/wiki/Orgone.  Though it is notable, however, that famous scientists such as Galileo, Hypathia, Tesla and  Pythagoras, but to name a few, were also refuted as having no empirical support – including all those who first claimed the Earth to be round and not flat!

Making your own Orgonite Muffins are Easy to Make at in-class or at home, Materials needed are:

Beezwax or EcoEpoxy Resin

Large Stir Spoon

Small crystals, even the smallest is great

2 kinds of scrap metals such as copper shavings (look around in your Mom and Dad’s garage or ask your teacher or local welder for some scraps)

a bit of paper and tape

Muffin Pan

For more instructions, visit here:  http://beeswax-orgone.com/make-an-orgone/; and here:  http://www.orgonite.info/how-to-make-orgonite-hhgs.html.

Orgonite Generators are said to turn negative energy into positive energy, purify the atmosphere, detoxify water, ends drought, help plants grow better, repel pests, require less water, Inspire a pleasant demeanor and balanced, happier moods, and help awaken your innate senses.  We first made one with paper and a bit of goldleaf, our compass, ruler and marker – drawing on the paper, a geometric flower of life, adding positive words.  We felt it generating positive energy and so thought it was an orgonite generator.  To truly test our generator we would have to first make a blank one with the gold, one with the flower of life, one with tiny words on it, and one without, and test each one in the garden to see if it attracts life, or if the flowers around it perk up!  Then, to document all of that!  But then, we read that Reich’s devices were said to “generate” only when in a container.  Otherwise they only “accumulated” the energy – hence, we believe what we made is an orgone accumulator (adding together inorganic and organic materials). Besides not being contained in a container with beeswax or EcoEpoxy, ours only had one kind of metal, and had no crystals.  So our next step is to make the Eco-Epoxy muffins!

Here is a photo of one of Reich’s generators designed to do cloudbusting and make rainfall.  (Photo: Extracted January 28, 2014 from: www. Wikipedia. Org / wiki / orgone.)  People who make homemade orgonite generators have we believe, good intentions – putting positive feelings into our environments.  Though, unfortunately, most generators have been made with epoxy fiberglass resin, that is reportedly not very good at all for the environment, in general.  Thus, our personal concern is whether crystals “like” being encapsulated in epoxy (as it is also apparent that crystals are living and have feelings!  Our sense is they would not like being encapsulated in a non-eco-friendly substance.  So…..we searched and found alternatives that are earth-friendly.  3 Eco-alternatives:

1. Beeswax.  Yellow Gold in color. http://beeswax-orgone.com/make-an-orgone/.

2. EcoEpoxy.  Clear in color and others.  http://www.earthsafefinishes.com/EcoEpoxy.html.

3. Ecopoxy.   Amber in color. http://ecopoxysystemscanada.com/.

http://www.westwindhardwood.com/products/ecopoxy/intro.php.

Our friend who makes generators at home, says, if you are wondering if an orgone device works or not try testing it on something that can re-act to your orgone device like a plant or lizard or other animal.  Testing may take minutes, hours, days or a week for optimal results.  Try taking digital pictures of the subject being tested to document it.  He says his generators makes his plants grow faster and greener and attracts interesting wildlife like frogs and lizards.  He also writes words on his like Love Peace Harmony Compassion Forgiveness Happiness and Oneness.

And we like this person’s Kirlian photos (infrared photo-technology), also forwarded to us by our friend Kevin.  Way cool.   http://www.orgoniseafrica.com/blog/improving-orgonite.  Are we, as human beings, orgonite generator? If we have contained within our bodies, more than one metal, organic and inorganic material, would we not also orgonite generators?  We would say yes, to an extent, though we do not contain non-carbon based crystals.  Crystals, are a different kind of life form on Planet Earth.    What about if wear a crystal, then?  Hmmmmm.  Good Science Questions.  Be sure and clean and care for your crystal, if you choose to wear one.  We believe Crystals have Feelings too!

Love Chemistry: Liquids and Solids http://www.science-lessons.ca/love-chemistry-liquids-solids/ http://www.science-lessons.ca/love-chemistry-liquids-solids/#respond Wed, 17 Jul 2013 15:00:29 +0000 http://www.science-lessons.ca/blog/?p=1620 Furthering and expanding our discussion on solubles, the in between liquid and physical state, here is another fun activity to try in the classroom.  Solids and liquids are generally easy to recognize. For example, slippery and wet items are usually liquids, like water, liquid soap, even blood. Solids are usually hard and easy to hold like a bowl, spoon, or even dirt. Solids have strong attractions between their molecules that keep them stuck together whereas liquids have some attraction between their particles, but the attraction is more flexible, allowing the particles to slide across each other. It is not always that easy to identify a liquid and a solid when they are happening at the same time. What happens if something is both a liquid and a solid?

In this activity students will explore the differences between a liquid and a solid.

Materials:

Cornstarch

Water

Large Mixing Bowl

Measuring cups (1 cup and ½ cup)

Instructions

  1. Pour the cornstarch (1 cup) into the bowl. Identify that it is a solid.
  2. Add ½ cup water to the bowl with the cornstarch. Identify that it is a solid.
  3. Mix the mixture, either with a large spoon, but fingers work great too.
  4. Let students explore the texture, grabbing handfuls and squeezing the mixture and then releasing.

How It Works:

This mixture seems to have both properties of a solid and a liquid simultaneously. This is because when pressure is applied, like when it is squeezed, the particles are forced close together. When the particles are closer together they begin to temporarily attract and attach to each other forming what chemists call “weak intermolecular forces”. What happens when the pressure is released? The solid seems to melt right before your eyes. This is because now the particles are not forced so closely together and are not as attracted and attached to each other and are able to flow like a liquid usually does.

Chemistry is an easy topic to teach to students of all ages, especially elementary school students as they are often very curious about how things change over time. Even looking at the leaves change in the Fall is an example of Chemistry.

Teaching Acids: Shine Your Pennies with Lemon! http://www.science-lessons.ca/teaching-acids-shine-pennies-lemon/ http://www.science-lessons.ca/teaching-acids-shine-pennies-lemon/#respond Wed, 12 Jun 2013 15:00:00 +0000 http://www.science-lessons.ca/blog/?p=1648 Ever had a lemon? Or anything sour? Then you have eaten an acid. Acids can be harmful like battery acid, but most acids are safe to eat like lemons, limes, and vinegar. In this activity students will explore how the properties of acids can be used to help clean objects. When acids are mixed with other compounds like salt, they form special molecules called ions. These ions are able to react with other compound nearby and have chemical reactions that can be used to change other substances, or in this case, clean the penny.

In this experiment students will experiment with the properties of an acid. 

Materials:

Measuring cup (1/2 cup)

Tablespoon

Pennies (dirty and old pennies work best)

Lemon Juice and salt

Taco Sauce

Instructions

  1. In a small bowl, mix ½ cup of lemon juice with a tablespoon of salt.
  2. Take a small amount of taco sauce and begin rubbing the pennies with it. (Use your hands, the more you scrub the better!)
  3. Periodically dip the penny in the lemon juice and salt mixture to help clean the penny even more.
  4. Scrub the penny for about 5-10 minutes until the pennies are nice and shiny.

How It Works: The taco sauce has vinegar and salt in it, which when combined form a super cleaning mixture. When salt is dissolved in vinegar it breaks into two ions (or charged particles), sodium and chloride. These ions are able to then mix with the copper oxide (a.k.a. rust) on the penny and dissolve the rust, leaving the penny shiny like new. The lemon juice and salt mixture does the same, with the salt dissolving in the lemon juice to form the cleaning machines, sodium and chloride.

When teaching Chemistry concepts, it is best to do hands-on activities. There are great vocabulary words that can be reinforced during Chemistry-related activities, like liquid, solid, acid, base, even words like chemical change, and physical change. There are lots of Chemistry topics around us everyday from how we cook foods to how our bodies breakdown the food we eat.

What makes Blue plant Oils Blue? http://www.science-lessons.ca/blue-plant-oils-blue/ http://www.science-lessons.ca/blue-plant-oils-blue/#respond Mon, 20 Aug 2012 21:54:48 +0000 http://www.science-lessons.ca/blog/?p=1520 Answer:  Azulene 

Have a look in your schoolyard and backyards, and see if you can find the Wild Flowers, Stones and/or Marine Life that contain Azulene (the chemical compound that would make them blue). Azulene is an organic compound, an isomer of naphthalene. Even though naphthalene itself has no color, azulene is dark blue, hence the dark color Blue in the essential oils of Yarrow, Blue Tansy, Blue Chamomile, Cypress and Black Spruce.  It is not surprising that the Spanish word for Blue is Azul.  The mushroom Lactarius indigo is blue because of a derivative of azulene.  Azulene is also found in some marine invertebrates, and in Lapis Lazuli stones found in Middle Eastern Persia.  http://en.wikipedia.org/wiki/Lapis_lazuli

The compound azulene has a long history, dating back to the 15th century as the azure-blue chromophore was first obtained through steam distillation of the German Chamomile flower.  This azure-blue chromophore was later discovered in Wild Yarrow flowers and named in 1863 by Septimus Piesse.  Its structure was first reported by Lavoslav Ruzicka in1937. With anti-inflammatory, skin healing properties, it is often in skincare products.  http://en.wikipedia.org/wiki/Azulene

Even though Wild Yarrow flowers, Achillea millefolium, grow in colors of bright yellow, white, pink, orange, salmon and purple, the oil of the Yarrow flower is azure blue.  Blue Yarrow oil is what is termed as volatile as it has “proazulenes”, making it blue.

www.essentialoils.co.za/essential-oils/yarrow.html

Yarrow oil is both a sweet and spicy smell, and is watery in its constitution.  Yarrow is Sacred, Holy, Healing and Spiritually Protective for many First Nations Peoples.  Thank you Mother Earth for these healing flowers, stones and marine life – and for Azulene and the color Blue!

Blue Tansy essential oil also is a vivid deep blue color due to its azulene content.  http://en.wikipedia.org/wiki/Azulene.  It is wildccrafted from common wildflowers grown in Morroco and North Africa from thee daisy family.  The Latin name is Tanacetum Annuum.  Health benefits include natural antihistamine and anti-inflammatory.  Herbalist Peter Holmes says it as also a “qi” or energy regulator for the body.

The Olive Tree of Life http://www.science-lessons.ca/olive-tree-life/ http://www.science-lessons.ca/olive-tree-life/#respond Thu, 12 Apr 2012 20:49:20 +0000 http://www.science-lessons.ca/blog/?p=1467 Often known as The Tree of Life, The Olive Tree is this month’s focus on Elementary Science.  The passing of an Olive Branch has been longtime known as offering a sign of Peace. The Olive fruit, oil and leaves all have significant healing and strengthening properties for the human body.  In Jesus’ Biblical times, Noah had sent a Dove out of the Arc to see if there was dry land, and the Dove returned with an Olive Branch in its mouth to signify there was dry land and sparkling life beyond the waters of the Arc.  All of His sermons were given on The Mount of Olives.  In Greek mythology, the Goddess Athena brought the Olive Tree to the people for abundance and a long healthy life.

Here is an indoor and outdoor activity your class can do for learning the science of The Olive Tree.

Growing From Seed:

Here are some basic instructions for growing an Olive Tree from a seed, though most likely, the plant won’t ever bear actual fruit.  For some reason we are still researching, the only ones that bear fruit once growing, are the trees that are sourced from a cutting.  However, you can still have fun planting an Olive Plant in the classroom from a pit, and watch it grow through most of its stages.  Or, you can have your class visit a Nursery and retrieve actual cuttings to plant.

Materials:

Empty milk or juice carton (2 for each student)

Scissors

Compost

Sea Soil (Soil that has been fertilized with seaplants like kelp)

Cactus Potting Soil (sandy)

5/6 Olive Pits

Small pebbles or small broken terra cotta pot pieces

Desk-size piece of leftover cotton fabric

Thick Pencil or Pen

1/2 Spray bottles to share

First Carton:

1  Have all students bring from home 2 empty milk or juice cartons, and a handful of pebbles.

2  Lay out a piece of cotton fabric to catch dirt drippings

3  Cut the first carton down to about 3 inches and fill with compost.

4  Place the Olive seeds sporadically across the compost soil.

5  Once the seeds are in place, spray with water bottle to moisten the seeds.

6  Keep the seeds and compost damp (but not soaking wet).  Place them on window sill where they will receive lots of warm sunshine

7 With constant daily spraying and sunshine, germination will take place within several weeks.

Second Carton:

1  After the seeds have begun to sprout, cut the top off the second milk/juice carton.

2  In the bottom of the carton, poke the pencil or pen through the middle and create a hole about 1 inch in diameter.

3  Layer the bottom of the carton with 8 or 10 of the pebbles, not covering the entire surface, though enough to allow water to flow through.

4  With a ratio of about 1:3 mix seasoil with cactus potting soil and fill the carton to about 3/4.

5  Move the healthiest looking germinated seeds from the short cartons to the second taller cartons.

6  Water the seedlings well – only when the soil in the pot feels dry.

7  Keep the plants in the same warm, sunny area indoors – even if is warm outdoors, as the plants are still in a stage where they need extra nurturing.

8  As it grows, prune the lower leaves off of the Olive Tree as it begins to grow, to encourage its upward growth into a tree.

9  Transplant the small trees outdoors only if you live in a warm climate.

Planting From a Cutting: 

If you want to grow an Olive plant that one day bears actual fruit, it is better to grow from a cutting than the seed.

1  Find a friend or local tree nursery who would give you a small cutting of their already growing olive tree.

2  With a sharp set of scissors or branch trimmer, cut a small branch off a tree, just under where the “V” is (sort of two small branches in one).

3  Dip it in water and if you have some available, then dip the cutting in “root stim” (Comes in a small bottle and looks like this: (http://www.progressive-growth.com/proddetail.php?prod=34022).  Root stim is a plant hormone that can aid in getting a cutting to grow a root.  You could possibly borrow a bottle from a neighbor or a nursery may donate one to your class.

4  Follow the same instructions of the Second Carton section from above.  Keep the plant in the sunlight, Spray the Leaves, and water once a week.  It is important to spray the leaves everyday as this is how the plant will first take in water, whereas there are no roots as of yet.  Olive plants need lots of sunlight as they are originally a plant from the Middle East.

Note:  if you are planting from a raw cutting, it is always best to cut just under one of the “V’s” or “W’s” where the very new baby growth is, as this is what will grow new roots with best possibility.  The older wood pruned off can be saved for other activities, like handing someone an olive branch (sign of peace).

http://www.mediterraneangardensociety.org/olives.html

and here:

http://www.olivepicking.com/Pruning-Olive-Trees.html

Olive Tree Nursery Outing:

Have your class visit a local Tree Nursery.   Phone ahead and ask if they have any Olive Trees there to study.  If there are no Olive trees yet around to study, study some of the other trees at the Nursery.  If a trek to a local nursery is not possible, have a simple outdoor trek around the school grounds.  Ask the Learners to study the growth patterns of the tree branches.  If your school is close to the ocean, visit the beach and retrieve seashells that clearly show the spiral growth pattern.  It is called the Fibonacci Spiral. Here are some of the other plants and seeds they may find to see the Spiral: the Pinecone, in the Branch growth pattern of trees, the mini-fruit pieces of the Pineapple, the Artichoke flower, a Fern during its uncurling, and Seashells.

Science and Math are so intricately connected in all areas.  The Fibonacci Spiral and The Fibonacci Sequence is a great example of this. Fibonacci is a Number / Integer Sequence, that when applied in geometrical form, manifests in a Spiral as in that of a Pine Cone or a SeaShell.  The sequence was named after an Italian mathematician known as Leonardo of Pisa (or Leonardo de Fibonacci).  In 1202, he wrote a book called Liber Abaci in which he gives name to the number sequence.  There are historical examples of the sequence showing up in East Indian mathematics as well.

In Spiritual Theory, Life must look back on itself before it can move forward.  In Relation to the human species, we must look back toward our Ancestors to learn Wisdom and give Gratitude to Life in the Present in order to move into the Future in the best way and in the Best Direction.  Because in theory the Spiral is not quantifiable in the concrete sense; i.e. it is a sequence that is Infinite (no final end number), mathematicians use straight lines around the spirals to give it as close to a concrete geometric equation as is possible.  Hence, the spiral looks like a spiral of expanding squares as shown here, and is known as the Golden Mean Ratio.  In biological settings, The Fibonacci Sequence can be seen in the Spirals of the Pinecone, in the Branch growth pattern of trees, the mini-fruit pieces of the Pineapple, the Artichoke flower, a Fern during its uncurling, and Seashells.

To further see the mathematical relationship of the Fibonacci Number Sequence to the Fibonacci Spiral, you can visit our Math-Skills page: http://www.math-lessons.ca/blog/2012/04/05/fibonacci-sequence/.

Blubber: Teaching About Sea Mammals http://www.science-lessons.ca/blubber-teaching-about-sea-mammals/ http://www.science-lessons.ca/blubber-teaching-about-sea-mammals/#respond Fri, 26 Nov 2010 04:54:06 +0000 http://www.science-lessons.ca/blog/?p=1053 Want to really get your elementary kids interested in learning about sea mammals such as whales and walruses?  Then teach about blubber! If you’re not familiar with the term, it’s nothing so disgusting as it sounds.  Blubber is the part of the sea mammals that keeps them warm. In fact, before you start this experiment, you should make sure that the kids understand this salient point. At the end of this, students should know that blubber is the fat layer beneath many sea animals’ skin, and that this layer is an insulator that helps sea mammals to stay warm.

To perform this interactive exercise, you’ll need some rubber gloves, a large bowl, ice, water, an outdoor thermometer and some solid vegetable shortening. Before you begin, explain to the kids that whales, dolphins, seals and porpoises are mammals, not fish. Among other things, this means that they are warm blooded. Explain that a warm-blooded sea creature’s body temperature stays constant and doesn’t adjust to the surrounding temperature.  And make sure they know that in order to maintain a constant temperature, these sea mammals need a way to stay warm when the area around them gets cold.

Now explain that the way these animals stay warm is through an extra layer of “insulation” beneath their outer skin.  Tell them that the activity they’re about to do will show how this blubber keeps the animal warm.  Divide the students into several groups.  Give each group a large bowl filled with water and plenty of ice, and a rubber glove beside it. Coat each glove with a layer of vegetable oil and have the children repeat the action, putting on the glove and submerging their hand. Ask them to write down their responses.

Have each student put on the glove and submerge their hand in the ice water and tell if they think the water is warm, cool, fairly cold, or very cold.   Now, again, ask them to write down how cold they felt the water was.  Almost everyone will report that their hands are much warmer with the vegetable oil.  Explain to the students that the vegetable oil protects the hand from the cold water in exactly the same way that the blubber protects the whale or dolphin from the icy water around them.

Your students will have a lot of fun with this. More importantly, they will have a greater appreciation for how Mother Nature has protected some important sea animals.

Creating an Ocean Theme in Your Elementary Classroom http://www.science-lessons.ca/creating-an-ocean-theme-in-your-elementary-classroom-2/ http://www.science-lessons.ca/creating-an-ocean-theme-in-your-elementary-classroom-2/#respond Wed, 10 Nov 2010 20:02:10 +0000 http://www.science-lessons.ca/blog/?p=990 When it’s time to teach your elementary kids about oceans and sea life, it’s a great idea to decorate your classroom in an ocean theme.  There are lots of ways of doing this.

Here are a few favorite ones:

Give the children a preview of the types of sea creatures that they’ll be learning about starting next week. Ask them if they have favorites. If so, write on the board each of their name and their favorite sea creature.  Give them a day or two to find out as much as they can about their favorite. Have them write interesting facts about the creature on index cards.  You can provide magazines or books to help them.

  • Have the students draw their favorite fish and cut it out, as you hang green and blue crepe paper across the classroom, simulating seawater.
  • During the week when you begin teaching about ocean life, continue decorating the room by having the children make jellyfish out of paper plates that they color.  Give them glue or tape to hang yellow, red and / or pink crepe tentacles from their “jellyfish.”  Hang these from the ceiling near your crepe “waves.”
  • Spend some time brainstorming with your students things that could be found on the floor of the ocean. Some ideas include a sunken ship, a clam, a starfish, an octopus cave, etc.  You can decorate areas of the room as these landmarks.  For instance, you could decorate a bookshelf to look like a sunken ship.
  • At the end of the week, ask the children what they’ve learned about the ocean and the creatures that live in it.  There are also several good educational films and film strip series that you can show, as a way of finishing your ocean unit.
  • Finish the week with some sea-related treats to eat.  For instance, you could make starfish-shaped cookies.  Or create an “edible aquarium.” Make this by adding some blue food coloring to soft cream cheese, which you put on melba toast.  Top it off with a few goldfish crackers.

By the way, be sure to let your students take home the sea creature that they created earlier in the week, as a memento of the fun and educational time they had.  Their parents are sure to enjoy displaying these!

Make a Nest & Bird Feeder http://www.science-lessons.ca/make-a-nest-bird-feeder/ http://www.science-lessons.ca/make-a-nest-bird-feeder/#respond Tue, 26 Oct 2010 16:53:40 +0000 http://www.science-lessons.ca/blog/?p=939 The early fall weeks of the new school year are a good time to teach your elementary students about the birds that live around them.  This is the time of the year when the birds that are still around, are looking for shelter and for something to eat.  That gives your kids the opportunity to learn about their feathered friends by working on projects such as a bird nest and a bird feeder.

Let’s talk about the nest first.  On a day when the weather is not too chilly, take the children outside and go on a nest hunt.  Have them look in an area with plenty of trees for a real nest.  As you look at it together, (or talk about it if you don’t happen to find one that day) explain to the kids that the birds build their nests one stick, or leaf, or piece of paper at a time.  Tell them also that the bird must first hunt for all of the materials needed to build the nest.

When you return to the classroom, tell the students that, based on what they learned, they are to make their own bird’s nest.  Tell them to use supplies that they find in the classroom (Make sure there are things in the classroom such as paper, sticks, grass, yarn, etc.).  To hold the pieces together, provide something like clay and then watch your kids’ creativity shine!

On another day, continue your study of birds by having your children make an actual bird feeder. Here are some possibilities:

  • Make a bottle bird feeder by cutting a big rectangle out of two opposite sides of a large bleach bottle (aired out empty at least 24 hours), or other large empty plastic bottle.  Fill the bottom with birdseed and then tie a piece of string around the neck and through the handle. Then hang it outside.
  • Make a milk carton feeder by cutting windows out of two opposing sides of a carton. Make sure you leave two inches at its bottom.  Place a pencil through holes in the sides to make a bird perch.  In the top, punch a hole and tie string through it and make a loop.  This is for hanging the feeder.  Your kids can paint it for additional fun and flare.  After it’s painted, put bird seed on the bottom and then hang it outside.
  • Make a Potato Chip Can Feeder by cutting two triangle holes in two sides of a Pringles can.  The bottoms of the triangles should be an inch from the can bottom, and should be parallel to one another.  Punch a pair of holes near the top and lace string through them. Tie the string into a loop for hanging the can outside.  Place birdseed on the bottom of the can and it’s ready for use.

A couple of projects like this will not only teach your kids about birds, but will make your kids love these winged wonders.
