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 use chocolate to explore how the Sun transfers heat to the Earth through radiation.

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 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).

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.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this activity, learners will discover why there are holes in bread.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this activity, learners separate the protein from milk and and use it to make their own glue.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.
