This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

Get all wrapped up in a lesson about skin!

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

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 discover the importance of maps and scale as they work together to create a map of the classroom.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

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

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

Learners construct and launch paper helicopters.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.
