Investigate a flower's power of marketing by making an imitation flower that successfully signals a bee (or other pollinator of your choice) to visit.

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this outdoor activity and game, learners roundup a "herd" of hopping insects and find out how many different kinds or species are in their herd.

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 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 is a classic exercise for visualizing the scale of the Solar System.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this activity, learners model ancient lunar impacts using water balloons.
