In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

This activity is designed to let learners measure their reaction time or response time to something they see.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners explore Charles' Law in a syringe.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.
