In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity, learners investigate the olfactory system by conducting several experiments.

In this activity, learners make a barometer, an instrument to measure change in air pressure.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this math lesson, learners rotate through various centers while comparing and ordering objects according to length.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels

Can gelatin (like Jell-O ®) change the speed of light?

In this activity learners will plant grass seed and track the growth of the grass over time.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this activity, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

In this activity, learners use their sense of smell to explore the world on the nanoscale.
