Get ready for a yummy taste test! Just pour the milk -- and make sure you have some chocolate chip cookies on hand.

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.

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

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

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.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

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.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

In this project children discover, identify, and sort seeds from a variety of fruits and vegetables

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.

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

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

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

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

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

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

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 project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

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

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.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

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.
