In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this activity, learners create a map showing the origins of spices and herbs from a favorite recipe(s). Learners first research the origins of the ingredients and then locate them on a world map.

In this geology activity, learners use a microscope to discover and identify the components of sand.

In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.

In this activity, learners investigate variations in human traits. This allows learners' natural curiosity about their identity to draw them into the study of heredity.

Learners participate in a variety of activities modeling different disabilities.

In this activity, learners compare different types of salt crystals under a magnifying glass.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.

This activity shows learners (with adult supervision) how to make a Glitter Globe, a fabulous toy that shimmers when you shake it.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
