Primate Evolution- Family Ties
If humans evolved from apes, why are there still apes? Using captivating pictures and videos of our primate cousins, young biologists examine evidence to dispel one of the most common misconceptions about human evolution. Depending on...
Curated OER
Jewel of the Earth
Students investigate several organisms, set sticky traps to collect them, and attempt to identify and classify them using a variety of sources. The origins of the organisms are traced and their adaptive features examined.

Plant Features
Pine needles are actually modified leaves. In the 16th installment of 20, young scientists explore plants. Through an analysis of leaves — shape, veins, and edges — pupils see how to classify plants based on structural features.
Curated OER
Aquatic Ecosystem Exploration
Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...
Curated OER
Donut Sort
Third graders create dichotomous keys using donuts. In this dichotomous lesson, 3rd graders review what a property is and sort donuts by a specific property. Donuts are kept in plastic baggies for the activity so they can be enjoyed by...
