Squishy Circuits
VAST Region 3 Conference-
One of my new favorite activities. Today we were learning about Ionic and Covalent bonds. Salt is an ionic bond and is a good conductor and sugar is a covalent bond and is not a good conductor.
LED lights and the connectors for 9v batteries are really inexpensive on Amazon. We are going to do this project again when we look at electricity but we will need way more LEDs, maybe 10 for each group. The dough stays fresh for a few days and one batch makes a lot. I used one batch of each for my classes and split them into groups of 2-4. The LED's rust after a few uses, so I am going to wipe them down next time.
