Natural Science: How Do Crystals Grow?

A crystal is a special type of solid where the particles are arranged in an orderly and repeating pattern. When solids are dissolved in water, they form a solution, like when salt and water mix. As particles dissolve in water, the particles of the solid separate and distribute evenly throughout the mixture. Sometimes two dissolved […]

Love Chemistry: Liquids and Solids

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 […]

Teaching Acids: Shine Your Pennies with Lemon!

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 […]

Hands-Free Balloon Blowing

Now that we have tackled, Liquids and Solids, we move on to the scientific properties of Gas.  There are three states of matter: solids, liquids and gas. Unlike liquids and solids, gases are a challenge to “see” because the particles are so small that they are almost invisible. We can collect gas when we blow […]

Slimy Creations

In chemistry, there are two important terms, soluble and insoluble. This month, have fun making slimy creations to teach this science concept.  If a substance is soluble, it means that it is easily dissolved in another solution. For example, sugar is soluble in water. However, if a substance is insoluble, it does not easily dissolve […]

Pennies in Motion: Newton’s Law of Physics

Newton’s 1st law of physics states that an object at rest will stay at rest, and an object in motion will stay in motion. This is an easy physics concept that can be taught to students of all ages. For example, when a bowling ball is rolled down a bowling alley, according to Newton, it […]

Spring Treasure Hunt: Wild Edible Science

For our Spring Treasure Hunt this year, we looked around the schoolyard and in our backyards for budding edible flowers and this is what we found so far – some being edible and some NOT.  Blue-Eyed Grass (See Photo to left), Grape Hyacinth, Crocuses, Daffodils and Narcissus.  Blue-Eyed Grass (Sisyrhynchium bellum) is a pretty 6-petalled native […]

Science of Olfactory Response in Deer, Racoons and Coyotes – Saving our Edibles

In this article we discuss our landscape experiment of preventing racoons from reaping the entire harvest of the plum tree, while at the same time, welcoming and sharing the flowers with the resident deer.  The racoons were eating all of the plums from the tree (not sharing!) and then leaving a huge mess afterward, with […]

Automaton: Elementary Science of The Old-Fashioned Robot

This month’s Elementary Science feature is about the very early example in science history of what today we call a sophisticated robot.   An Automaton is basically an old-fashioned robot, or a “non-electronic moving machine “. Merriam-Webster’s dictionary describes one as: 1. a mechanism that is relatively self-operating; especially : robot 2. a machine or control […]
