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 (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

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

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.

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

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 sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

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

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

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

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

This is an activity in which learners create magic wands from a variety of materials making their choices by considering what kind of magic they want to make.

Did you know that a Slinky makes a handy model of earthquake waves?

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