Science Fair Project Idea
Every spring, gardeners around the world get ready to plant their summer gardens. They turn the soil over in their garden plots and add nutrients to the soil. Then they plant their seedlings and wait for nature to provide a bounty of fruits, vegetables, and flowers. But nurturing the garden doesn't stop there. In order to get lots of fruits and vegetables, the gardener must eliminate factors that can hurt the plants. Sometimes, chemicals in the soil from other plants and trees can hurt a… Read more

Science Fair Project Idea
Have you ever looked around and noticed the plants and animals that grow in your neighborhood? Have you ever visited friends in another part of your city, state, or even another part of the country? Have you noticed whether the plants and animals where they live are similar to those growing near you? What would it be like to live where they do? Why do certain plants and animals grow in one area, but not in another? In this science fair project you will learn about biomes and how different… Read more

Science Fair Project Idea
Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one important variable among many that determine the ideal conditions for seed germination.

Earthworms are important for the soil and fun to study. In this science project, you will find where earthworms like to stay when food is around. Will they gather around the food, take food with them in their tunnels, or not be attracted to the food at all? You will fill four pots with dirt, add food and worms, and track their activity over one week to find out! Read more
