In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

In this activity, learners stain fabrics--on purpose!

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

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

This activity features two connected hands-on activities about dinosaur bones.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

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