Over at Mama Scout, they conducted an experiment to see which foods would cause the most activity when paired with yeast. Have kids make a hypothesis and prediction: What variable will create the most bubbles / activity? Record yeast activity in a notebook. What was your conclusion?
materials:
freezer bags
warm water
measuring spoons / cups
yeast
variables (such as: water, grape juice, lemon juice, maple syrup, sugar, and candy)
how to:
Combine 1/4 cup of water, 1 tsp of yeast, and 1 tbsp of the variable in each bag. Now, watch the bubbles go!
