This science project teaches students to classify different shapes of leaves.

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

This science project challenges students to learn about and classify weeds and discover new practical uses for weeds.

Get your child math and science savvy with this fun outdoor classification game. Using chalk, your child will classify what she sees in the natural world.

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

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 activity, students will be challenged to describe and count the ways a toy moves from one position on a grid to another.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

Tree rings can tell the age of the tree but also information about the world. This science experiment uses tree stumps to discover new facts.

Science fair project determines relationship between number and variety of insects and spiders by collecting and counting invertebrates in a ecosystem.

Which music genres have the fastest tempos? The slowest? This experiment determines if there's a relationship between beats per minute in a song and its genre.

This science project has students collect wood samples and invent new uses for different types of wood based on its properties.

This science fair project idea investigates the hardness property of minerals.

Your preschooler is familiar with the colors in their crayon box, but can they find these colors in the world? Take them on a scavenger hunt to find out!

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.

This science fair project teaches students the differences between fruits and vegetables.

Invite your kindergarten marine biologist to practice in scientific identification and categorization while creating a lovely treasure box.
