In this activity, learners construct a home-made journal with simple, everyday materials.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this activity, one person acts as a human robot while another acts as their developer by programming their actions.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this water activity, learners discover ways to move water across the water table.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
