Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.

In this activity, learners discover a brain process called habituation.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

Learners use Duplo bricks to build antibodies with shapes that match model viruses.

This quiz lets you estimate your annual radiation exposure.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

Learners draw and cut out shapes of organs from construction paper. Then they attach these organs to the body of one learner to make a life-sized map of all the internal organs.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.

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.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

In this lab (Activity #1 on page), learners explore how we see color.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.
