In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.

In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this activity learners will plant grass seed and track the growth of the grass over time.

In this activity, learners create a colorful foam fountain by adding yeast to a chemical reaction. This activity introduces chemical reactions to young learners and teaches the concept of catalysts.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.

In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners will use bubble wrap to print patterns on paper and experiment with mixing colors.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In this activity, learners practice matching and subitizing as they create the longest domino train possible.
