Science Night Instructions

Welcome to Science Night!

Since we are sending home science with food, we thought it would be fun to focus on some science at work in our food. Below are videos to show you how to do the experiments we’ve prepared. Be aware that many of the tools we’ve given are used in multiple experiments, so you may want to scan them all before using up your ingredients.
