This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

In this activity, learners explore how to protect their skin while applying pesticides to plants.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this activity, learners practice counting and multiplication as they figure out how many animal body parts they have to examine as "Dr. Vet."

In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

In this activity, learners will turn healthy greens into crispy snacks. Explore concepts of nutrition, dehydration and cooking to create healthy food.

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this online activity, learners measure their pulse rates and investigate how their pulses change when they engage in different activities.

Combine math and exercise with this activity. Learners count how many times in a row they can skip rope or throw and catch a ball.

In this fun activity for any size group, early elementary learners complete physical challenges while playing a game. Learners add new challenges to the "wheel of fitness" that they want to try.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?
