In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this paleontology activity, learners explore the system behind dinosaur nomenclature.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this activity, learners use simple materials to create giant bubbles.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.

In this activity, learners explore how nanosized structures can create brilliant color.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
