This weather spinner will improve observation skills by encouraging children to examine and track weather details and patterns.

Encourage your kindergartener to investigate and chronicle the weather she observes during the coldest months of the year.

The weather is a key kindergarten science concept. With this activity your child will learn about wind direction and create a self portrait, too!

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

Your child grows a green thumb and flowers with this seed planting activity that also celebrates the 100th day of school!

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

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.

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

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 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.

Make a spring collage with your child to get them outside and those creative juices flowing!

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

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