They dissect a chicken wing, comparing it with the parts and functions of the human arm. Scale animal models are used to help learn about livestock weight estimates and weight gain.

A germination study of seeds which produce albino or normal green corn plants helps students understand genotypes and phenotypes. A small jar of shelled corn is used to simulate a grain bin as students learn to estimate weights, numbers, and volumes.
Students build growth chambers to observe how various light colors influence plant growth.
They use varying fertilizer rates in an attempt to grow larger, healthier plants. First in a series of soil conservation and water quality projects, this kit tackles the high-priority problem of soil erosion.
