We hit record attendance for the Slime Lab this week! Students had a blast learning about chemical reactions and the periodic table of elements. Kids played with baking soda and pipettes full of colored vinegar, creating fizzing reactions. They looked at the chemical formula for the reaction and build molecules models. And, of course, there was lots of colorful stretchy slime making and playing!

Read: The Elements: A Visual Exploration of Every Known Atom in the Universe by Theodore Gray (available at the San Anselmo library).

Play: Build molecules with a molecular kit (we used Old Nobby). It’s like Legos with a chemistry twist!

Play: Make slime with this simple recipe: Mix 1/2 cup PVA glue (Elmer’s glue) + 1/2 tsp baking soda + a drop of food coloring. Add 1/2 Tbsp saline solution (must contain boric acid and sodium borate; Bausch&Lomb Advance Eye Relief works well,) and mix with a spoon/ladle until stretchy slime forms. Enjoy!

Thank you to all the amazing parents who made this lab possible.
