Year 4 Environmental Science Projects

What's the best way to make DIY compost? Kids will learn about aerobic and anaerobic decomposition while learning to appreciate the value of composting.

Science fair project that examines albedo, and how this information is applied in the design of cars, sportswear, and other items. Which colors reflect light?

Science fair project that examines condensation and the conditions needed in order for dew to form.

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Science fair project that examines the different types of precipitation, evaluates the density of snow and calculates the ratio of snow-to-liquid.

Science fair project that examines how winter storms form and the relationship between temperature, moisture and snow.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

Learn about savanna flora and fauna in this science project! Take a look at characteristics of tropical grassland plants and animals that help them survive.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

How do icicles form and what do they look like? Do this free science fair project and watch the formation of icicles occur right before your eyes.

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

This science fair project idea's objective is to understand the concept of air pollution and examine the quality of air in our environments.

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?
