Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

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

Learners carefully look at four known household crystals.

In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.
