In this activity (on pages 23-29), partners use the Plant Traveler Cards, along with a world map and map worksheets, to follow plants such as cassava, chocolate and coffee that grew first in one part

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

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 try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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 which plants and animals have symbiotic relationships and how this impacts each organism.

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

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

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 activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

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

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

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

Put on a pair of gloves and be the conductor of your invisible orchestra!

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.
