In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

In this forensics activity, students will explore the methods that investigators use to confirm the authenticity of handwriting.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

This activity introduces learners to the structure and properties of carbon nanotubes.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this activity, learners will observe and record living things with in outlined outside space.

In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In this activity, learners will code an algorithm to make it through a maze.

In this activity, learners use simple materials to construct a balloon-powered pinwheel. The pinwheel is a great way to investigate Newton's Third Law of Motion.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.
