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

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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 interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
