Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science activity, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

Welcome to your new job as an astrophysicist, astrobiologist, engineer, or research scientist at NASA. Your job is to search for alien life in our solar system! Throughout a unit of activities, learners search the galaxy through...

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Yes, scientists say, there is other life in our solar system! And the best place to look is on Europa, a moon of Jupiter. Here, learners mimic the techniques scientists use to gather information about objects in our solar system, write...

Pupils work with the teacher as they go through the vocabulary. At the end of the lesson they are asked to define the terms without their notes.

Space diving refers to the act of jumping from outer space and falling through Earth's atmosphere before parachuting to land. Scholars learn about this extreme activity and study the layers of the atmosphere they must conquer in the...

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

Students demonstrate comprehension of the energy sources of various cycles by completing mini stories. They demonstrate analysis of words by defining individual word parts and combining them to form definitions. Students demonstrate...

Learners explore mimicry and crypsis, participate in hands-on predator-prey activity, and practice calculating averages and graph results in histogram.

Students research an assigned biogeochemical cycle. In this cycle activity, students need to determine that all cycles need energy to continue. The students will look at a given cycle to describe it, research and draw an assigned cycle,...
