In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

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.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this construction activity, students use a 2-liter bottle to build a fly trap.

In this activity (on pages 10-15), learners investigate starch in human diets and how plants make starch (carbohydrates) to use as their food source.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this challenge, learners figure out how to make a juice stain disappear.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
