From Rocks to Soil

120 min lesson

In this lesson students explore weatherization (physical and chemical) by doing a series of short experiments that demonstrate how rocks and minerals are broken down into soil. Expand this lesson further by taking students on a field trip to look for rocks breaking down into soil.
Apple Faces

30 min lesson

Apples rot and turn brown because they take in oxygen and give off carbon dioxide. If apples are stored in cool temperatures, they will rot slower than they would in room temperature. Other conditions such as humidity, and the storage atmosphere also effect how quickly apples rot.

Microbe Observations

Select four slices of bread preferably from a loaf without preservatives (this will speed your mold growth.) Give each piece the following treatment and then place the slices into a “treatment-labeled” Ziploc bag. Store the bags in a warm, dark place for incubation
Making Bioplastics

50 min lesson

Common plastic is made from petroleum, a fossil fuel and non-renewable resource. Increasingly, plastic products are being made from biomass which is made from renewable resources, often by-products of agricultural processes.
Besides being just plain fun, making butter is a great way to demonstrate one of the many ways food is made, as well as how liquids can be converted into solids. You can get more in depth and use the lesson to demonstrate phase change.
This lesson is a delicious way to teach students about one type of physical change that matter can under go - liquids transforming into a solid.
