Rainbow Ice – A Science Experiment

Have you ever made rainbow ice? Neither had I until recently. This was a fun experiment that can teach chemistry  or chemistry terms on all different levels, such as how sodium (Na) from salt (NaCl) reacts to ice by heating it up and melting it, how salt diffuses in water – quicker if the water …

Chemistry: Energy Shell Peace Flags – II

This is the ultimate follow-up to the previous Chemistry/Art/Peace lesson called Chemistry: Energy Shell Peace Flags. Before you can attempt the rest of this lesson, you’ll need to see how this is done… click here. Recently, some middle school students got in on the process of making these and chose which elemental groups they wanted …

Because of the school’s alternative nature, I was allowed to use whatever creative methods I wanted to help the kids to understand math and science. In comes the Periodic Table of Elements. It’s pretty fascinating stuff, but not so much …

Fun With Microscopes I

Oh microscope, how do I love thee? Let me count the ways! Microscopes have to be one of the coolest inventions ever (the actual inventor is up for debate, but many vote for Zacharias Jansen, and later refined by Anton van Leeuwenhoek). To be able to manipulate a small amount of light enough to bend …
