Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

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 lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

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

In this art activity (page seven of the pdf), learners will use their creativity to make a "motion collage." Each student will be encouraged to draw a picture of something that moves to be a part of t

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

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 math lesson, learners explore polynomial and rational function patterns.

In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.

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 investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

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

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
