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

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

Learners measure irregularly shaped bones using a variety of measurement methods and tools. Then, they measure again using standard conventions and metric tape measures.

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

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.
