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

Blend art and science in this hands-on activity that shows your kindergartener how primary colors combine to make secondary colors.

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.

Hold a magnet marathon! Explore the power of magnets with your kindergartener in this entertaining and simple science game.

Invite your kindergarten scientist to conduct this color mixing experiment to discover which primary hues make a rainbow of secondary colors.

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

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

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?

Get a better understanding of water content by dehydrating carrots.

Learn how different types of soil affect how animal tracks form in this experiment!

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.

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

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 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.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

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.

Here is a kindergarten activity that blends art and science by using magnets, paint, and objects found around the house to create a picture.

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.

Let your kid experiment with textures among fabric and other materials that are smooth, rough, soft, or slippery—and then they'll make a texture book!

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

Make scented sensory cloud dough. Add it to a sensory table, activity station, or put it in a baggie for extra at-the-park entertainment!

This recipe makes bubbles that not only blow up nice and big, but do tricks and experiments! How do you do it? It's not a secret, it's science!
