My 10 year old son, Ethan, and I had fun in the kitchen this morning making pies for Thanksgiving. It was a great way to learn about food science. We decided to make a Lemon Meringue Pie. First, we needed to look at the formula (recipe) and talk about all the ingredients that we needed. We uses several types of measurements - liquid measuring in ounces, solid measuring in measuring cups and spoons (next time we'll try using a recipe with weights), and counting of individual items (such as eggs). When mixed together the ingredients for the filling we talked about the chemical changes that were occurring in the pot as the ingredients bubbled together and thickened. As we whipped the egg whites we talked about physical change as the molecules captured the air and coated the air bubbles. It was a great way to reinforce what he is learning in his 5th grade class without it feeling like homework. The best part is you get to eat the results!
Looking for a few more experiments for physical and chemical changes? Here's a related blog post you might like at Owlcation.

You could see the excitement as the boys in Cub Scouts Pack 16 entered Dutch Kitchen Bakery and gazed into the display case loaded with all kinds of delectable treats. They were soon whisked downstairs to the decorating room, where on the tables were all the fixings for gingerbread houses. Each boy had the chance to create their own masterpiece. They didn't know that even this activity had a STEM (Science, Technology, Engineering & Math) connection. Building a gingerbread house could be their first exposure to civil engineering which includes the design and building of structures. As they decorated, they worked through creating patterns in their designs. While they toured the bakery, they used math to calculate how many cakes could be baked at a time in all those ovens. They guessed 9 cakes per oven and multiplied it by the 12 ovens to come up with 108 cakes. They learned that recipes are formulas of ingredients and the weighted scales are for measurements. All the boys knew is they were having fun, as a mom it made me realize how many opportunities are around us which expand STEM learning.
