Learn how to make a food pyramid with animals in a a coniferous forest ecosystem around your home.

Climates with more snowfall have more coniferous forests and fewer deciduous ? Learn about how pine trees in a coniferous forest adapted to withstand snow.

In this experiment, young ecologists will learn about a type of edge effect: how trees and plants at the edge of a forest can act as a weed filter.

What is biodiversity? Kids will study different areas of their backyards to see which is the most diverse to learn about biodiversity and random sampling.

What are buttress roots? In this fun science project, make a model of a rainforest tree and learn how they help trees survive in the tropical rainforest!

Soil is made up of different layers. How far down do you need to dig to find the soil horizon, or the place where bits of leaves and branches become soil?

Camouflage is one of the most important animal adaptations in the African savanna biome. Kids create their own camouflage with this fun science fair project.

This science fair project investigates why the number of visible stars changes from place to place.

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

Science fair project that compares the biodiversity of fungi in different ecosystems by identifying species of fungi.

What is mulch? Kids will provide soil with a wet blanket of mulch and see if that helps keep drought-stricken soil damp.

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

In this simple science project, learn about what causes dew and what affects dew formation with a drinking glass, ice, and a soda bottle.

Test out the pH levels of soil in your backyard versus soil in more wild environments to solve this science case.

Learn how to be a bird scientist in this simple project of watching feathered friends in their habitat.
