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

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.

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

This simple activity is not only fun, it's also a useful way to organize children's closets — and offer kids some autonomy to boot.

This activity allows your kindergartener to translate what they observe into a beautiful poem.

What better way to nurture your child's imagination than by making a fairy house out of materials found in nature!

What happens when light hits a hard surface? Find out by conducting a simple light reflection experiment with your preschooler.

What's a crater, and how does it happen? Here's a kindergarten experiment with safe, nontoxic ingredients.

Try this activity with your child to explore what happens to rain (and the living things that need it) when it becomes polluted.

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

Use simple materials to build a "worm hotel" with your kindergarten soil scientist...and see what worms really do all day.

In this hands-on activity, kids learn what it takes to foster seedlings into full-grown plants, all in a regular old soda bottle!

Make some easy homemade yogurt with your young scientist, and see what a few 'live' bacteria can do in the right conditions!

Kindergarten algebra is a lot different than high school. In kindergarten math, algebra means grouping like things, or noticing what doesn't belong in a set.

In this Halloween-themed activity, young learners will find out what happens when they mix two household items together to create a surprising chemical reaction.

In this fun guessing game, your child uses his sense of smell and taste to figure out what is in the container. Here's how to play:

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?

Did you know magnifying glasses are magic? This hands-on activity has kids using magnifying glasses to engage with the world around them and look close to examine what they find.

What do you get when you combine science and fairies? Fairy scientists who make their own potion, of course! This activity promotes critical thinking skills as your child mixes, experiments, and creates their very own fairy potions.

In this activity, children will let their imagination run wild as they design and build a new planet in the solar system.

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!

Children use their design thinking skills and powers of observation to create and construct a bird nest.

In this activity, your child will be challenged to make a tower using paper cups.

Children learn the six parts of a plant...but do they really understand? Try this plant-themed meal plan to bring school science into the home.

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

Have your kid build an ice sculpture in this activity that's so fast, fun, and messy it's the perfect way to demonstrate how much fun experiments can be!

Children will learn all about cause and effect as they experiment with potion-making in this Halloween themed activity.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

Help your kindergarten science maven explore the water cycle without getting everything wet.
