In this 2-day lesson focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess board. Exponential...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...

Can you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

Students discover how crystal structures go together to create minerals.  In this earth science lesson, students work in groups to create 3-dimensional shapes of crystals that they then put together in a compact structure.

Learners identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative to...

Students explore the nature of the air we breathe by observing petri dishes that have accumulated particulate matter from the atmosphere. Students make mathematical calculations and inferences about the effect of this matter on...

Students calculate acceleration due to gravity.

Students examine an image produced by a cabinet x-ray system to determine if it is a quality bone mineral density image. Students write in their journals about what they need to know to be able to make this judgment. Students learn about...
