In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

In this activity, learners create handmade animal track stamps. Learners research animal tracks, draw the shapes on moleskin, and then stick the shapes onto blocks of wood to make stamps.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.

In this activity, learners use beads, which represent amino acids, to create protein bracelets. Learners examine the relationship between amino acids and proteins.

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.
