Students define food chains, recognize fossil park food chains and discuss man's impact on food chains. In this food chain lesson, students participate in activities to diagram a food chain and understand the impact of humans on the food...

Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

Transform young biologists into grasshoppers, lizards, and hawks as you teach them about food chains in an interactive life science simulation. Working collaboratively to act out three different scenarios involving these creatures,...
