In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

This activity combines learning about nutrition, math of measurement and proportion, and healthy eating. Start by distributing food packages with Nutrition Facts labeled.

In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.

This math challenge, played with two players or a whole group, engages your problem solving skills.

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

In this activity, learners make instant ice cream without using a freezer.

In this activity, learners cook amino acids and sugar to explore the range of aromas released.

In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this nutrition activity (page 2 of the PDF), learners will be split up into food groups (Fruit, Vegetable, Meat & Beans, Grain, and Dairy) and draw a picture of their favorite food from their g

In this activity, learners explore a bucket of sand and beach objects.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o
