Catalysts, reactants, or products? The final unit in the middle school chemistry module examines chemical changes. Tweens perform experiments to determine what factors impact the rate of chemical reactions, study energy changes, both...

Through demonstrations, hands-on activities, and discussions, young chemists explore water molecules and their polar characteristics. Groups design and carry out their own experiments to examine solubility, determine if the type of...

The Multimedia Discovery Missions collection is a series of 13 interactive presentations and activities that introduce young geologists and oceanographers to fundamental concepts involving the Earth’s crust and ocean sea life. Benthos,...

Photosynthesis, extinction, biomimicry, and bioremediation. Young environmental engineers study these processes. Using photosynthesis as a model and biomimicry as an example, groups research how nature provides hints for engineering...

Oh, if only Sir Isaac and Bernoulli could see us now. Even Orville and Wilbur would be amazed by what engineers have designed using their ideas. Next generation engineers put these principles to use as they use what they learn about...

Engineering design-based activities make learning science fun. Young engineers design dams, lifeguard chairs, musical instruments, candy bags, and much more. They also use measurement skills to solve the mystery of the missing pin. Each...

Add a little power to your biology classes with a collection of 18 colorful presentations that cover everything from an introduction to the scientific method to lab safety rules, from acids to vaporization, Although designed as an AP...

Different ecosystems thrive in various places, with a variety of habitats, including specific plants and animals that have adapted to survive in those specific conditions. But they all have one thing in common: all of the energy that...

Explore the common makeup of all organisms and objects in our world, big and small, with a collection of resources about the states of matter.
