In this activity, learners will explore how different bird beaks work and discover what birds can eat based on their beak shape.

In this activity, learners make a model of a beehive using simple materials.

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

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

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this activity, learners explore the Great Plains.

What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.
