Word color association is just a fancy way to talk about the way we connect colors with words.

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

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

Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

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

This project examines whether people's taste perception is influenced by what they see.

Help your child explore chromatography, which is the process of separating colors or pigments, and create a neat art project in the process!

Help your kindergarten or first grade child use his creativity to make a beautiful magnetic patterned structure while discovering the wonders of magnets.

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!

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

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

Show your preschooler how to make a print of a butterfly using her hand as a tool--a great way to stimulate her sense of touch.

Can you fool your eyes and your brain with an optical illusion? The purpose of this science fair project is to demonstrate various kinds of optical illusions.

In this activity, your child will transform an egg into a glowing, bouncy "ball" that they can play with.

Science fair project idea that examines different physical characteristics of a chosen animal. Make educated guesses about evolution based on animal's form.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

In this experiment you will replicate the mummification process by making a hot dog mummy.

The goal of this fun science fair project idea is to microwave candy and investigate: do some colors of M&Ms melt faster than others?

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

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

Here's an easy experiment that lets your first grader practice the scientific method, while watching a caterpillar eat.

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.

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

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

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

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?

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

Magnets may hold up papers on the fridge, but is it the paper that attracts them? Find out more with this kindergarten science investigation.
