These colorful teaching models are designed specifically for hands-on use with young children. Made of resilient, non-toxic, EVA foam, the removable pieces stimulate problem-solving skills and develop small motor skills. Every model is accompanied by a reproducible activity card containing background information and extension ideas. teachers can cut out the task card and use it in learning center or as a group activity. This teaching model is designed to introduce students to the "life and times" of the ant. It illustrates the major stages of the life cycle and the ants extensive social life. Grades K-6.

Challenge your class to solve a murder using a bloody stain left at the scene of the crime. Using simulated Neo/Blood, they'll identify whether or not the stain is actual blood. Then they'll solve the crime by performing ABO and Rh typing of both the stain as well as samples from the victim and several suspects. Students will learn about blood groups, blood typing and how blood stains can be used in solving crimes. Simulated Neo/Blood looks and behaves like real blood, giving you and your class quick, easy and completely safe results. This revolutionary substance realistically simulates agglutination. It even contains simulated, microscopic blood cells - of the same size and concentration as in actual human blood.
A great economical model to teach dental hygine and demonstrate the correct way to brush teeth and gums. Large lower and upper jaws, 6" wide on the back, 5" long. The two jaws are connected by bendable spring wires for easy demonstration. The model is 17" long, when it is completely laid flat. Included a 10" long tooth brush with nylon bristles.
