Molecules & Atoms & Ions, Oh My!
Today, we’re breaking matter down into its tiniest pieces with our small humans. We will start with atoms, the building blocks that make up everything around us. Next comes molecules and the surprising ways atoms connect with each other. Expect to spot a few familiar favourites along the way, including H2O and CO2. The elemental table will swing by as we learn about what occurs naturally in nature, what is man made, and we will dip into the idea of acid and alkaline substances. There will be lots of fun hands-on mini experiments to see proof of the existence of these invisible factors at work with each other.
Aquatic Invertebrates: Animal Water Testers
Did you know that invertebrates make up 97% of the creatures in the world? Just like molecules, they can be simple and tiny or large and complicated. In our lakes, rivers, ponds, and wetlands, they perform very important jobs.
Being able to identify them can tell you lots of things about the water they live in. Using some of our elemental learning from last week, we are going to do some citizen science and test the water to confirm our hypotheses.
