This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

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 about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

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 will pretend to be archaeologist using this chilling experience.

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 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 will investigate how craters are made and the different factors that contribute to size left from the impact.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity on page 9 of the PDF, learners make their own paint using chalk as a pigment and glue and water as binders. This activity introduces learners to special mixtures called suspensions.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

In this activity about electricity, learners explore what happens when you blow a fuse.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.
