In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this activity, learners will be introduced to citizen science projects that can be done from home.

In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this activity, learners explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

In this astronomy activity (page 6 of the PDF), learners will compare and contrast two planets in the solar system using data obtained from the internet.

In this online activity about heart disease, learners will pick one of three patients (based on actual patient histories) and help a cardiologist diagnose and prescribe treatments for him or her.

In this online activity about anatomy, learners will correctly order the path blood takes through the heart in order to absorb oxygen to deliver to the rest of the body.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

This is an online game that explores speed, range and momentum. Learners will pick the winners in a 16-team tournament in 3 events: Tug-o-war, sprint, and marathon.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.

In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.

In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.
