In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

This detailed lesson plan for a field trip to Canyonlands National Park in Utah (page 32 of pdf) teaches students about the habitat of bighorn sheep.
