In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners explore clouds and how they form.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this activity, learners explore rocketry and the principals of space flight.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

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.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
