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 indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

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.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

This is an activity to do when there is a solar eclipse!

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

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

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.
