In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this physics activity, learners will explore buoyancy.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

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 activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.
