In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

The goal of this activity is to design, build and test a house or toy for an animal.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.
