The Genius of Marie Curie

Two activities employ the use of kinematic equations for determining projectile ranges. They both require the use of a toy dart gun. Included in this resource are both the teacher's guide and student laboratory sheets. This is an...

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

What creatures lurk in the rainforest at night? Meet three of them in one short video. Part of a playlist exploring mammals, the video presents a look at night research in the Amazon. Scientists locate and photograph two bat species and...

How is it that the same animal, living in the same place, at the same time, evolved into two different species? As part of a larger series, an engaging video explains the rise of the chalicothere, the split in evolution, and eventually...

Continue the journey into the world of physics as you lead your class on a winding road complete with vectors and scalers. Pupils learn more about motion, direction, and velocity as they use these concepts to explore two- and...

How does this sound? It's a rockin' video starring two teenage girls talking about music, hearing, and the ear. Listeners hear that the ear does not only gather sound waves, but also helps us maintain balance. They also will get an...

Students design and build full-size boats made out of two-liter plastic bottles, chicken wire, and plywood. Then they race the boats, with the boat's designers "manning the hull", in the school's swimming pool.

Students discover that proteins that are the product of DNA translation are different for different species. They determine that by analyzing their mass and charge they can differentiate between two different species. They use some of...

Two recent studies explore tongue design and function- how they are used for lapping by dogs and for nectar retrieval by hummingbirds. [4:26]

Determine what young pupils already know about earth science with a brainstorming activity. After class members work together to complete a KWL chart about the Earth, they craft an acrostic poem to demonstrate their understanding.
