In this activity, learners explore the different heating properties of soil and water.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

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.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.
