It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.

Don't let your classes coast through school! Engage them in their learning as they build their own roller coasters to study potential and kinetic energy. Young scholars complete several challenges that require them to consider the...

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem. Groups...

A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

Mike and Kellie, a team of electrical engineers, demonstrate how to to design a contraption that accurately drops a marble onto a target. The materials needed and general instructions are provided on the website or via a downloadable...

With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...

Geology can be a lot of fun. Learners review geology related vocabulary, make flashcards, use encyclopedias to answer questions, then explore the formation of coal. They identify dates and order them into key time frames of geologic...

Students perform a simulation in which they work for a toy company and have to figure out how many marbles of different sizes can be made with the provided material. They must design their own experiment to figure this out.

Erratics, or drop-stones, are geographic abnormalities. Large stones that appear in unlikely places point to glacial movement. Lava flow also helps scientists determine timing of multiple Ice Ages. Watch this clip along with the four...
