In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

Build a house you can fit inside, using cardboard tubes.

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

This activity guide includes instructions for building a spectroscope using a standard classroom overhead projector.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

Water treatment on a large scale enables the supply of clean drinking water to communities.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

Learners build devices from rubber bands to test for invisible air pollutants.

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners investigate the history and development of agricultural biotechnology.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
