Fourth graders observe mealworms over a period of time and record any changes they observe. They record any changes in color, length, behavior, and any other noticeable changes, identify the stages of the mealworms, and create a chart...

Students put items in a plastic bag and watch the effects of composting. While completing the experiment, students answer questions and ask permission to start their own compost pile at home.

Fourth graders use local materials such as leaves and other plant matter; sand and pebbles to make soil. They plant seeds in the manufactured soil and in natural soil and then observe and record the results.

Eleventh graders investigate inverse functions.  In this Algebra II lesson, 11th graders use their prior knowledge of linear, exponential,and quadratic functions to create a graph of an equation they have never seen before.

If mathematicians know the secret to compound interest, why aren't more of them rich? Young mathematicians explore compound interest with exponential functions in the twenty-seventh installment of a 35-part module. They calculate future...

Young scholars read the story Ancient Ones about a forest that is connected to all the life around it. For this reading lesson plan, students also create a tall folding book about the forest.

In this agricultural education worksheet, students read 6 descriptions of bacteria that cause food spoilage.  Students then read 4 descriptions of preservatives that can be used to prevent spoilage.  The worksheet is meant as a...

High schoolers work in pairs to determine the age of a tree using two different methods in this experiment. They collect data about how trees change over time.
