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

Using a toy race car kids create a visual model of the Doppler Effect.

In this awesome science fair project idea, kids will be attempting to pick up different objects using snail slime.

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

In this project children practice the scientific method while playing with puffy paint.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.

This science fair project teaches students about wilting and browning of salad greens.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

This project makes young children uniquely aware of their sense of touch and its ability to alone give them information about the world around them.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

In this science fair project, young children notice and track changes in trees throughout the year.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

In this science fair project, young children discover what happens when two fluids that have different densities get together.

This simple project makes young children aware of their sense of smell and its capacity for providing them with information about their world.

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

In this science project, young children observe, record, and create collections of colors in their world and increase their powers of observation.

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

In this science fair project, young children observe, record, and create collections of shapes in their world and increase their powers of observation.

In this project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

This classic children's game demonstrates how sound travels through air vs. through a solid.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

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

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.
