In this activity, learners work together to create a life-sized drawing of the human nervous system.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

In this game, learners each represent a different organism in an environment. They build a web during the activity, and discover how all the players in an ecosystem depend on each other.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

In this version of tag, a large group of learners model how the body fights infection. Learners act as germs, as lymphocytes, and as the body's cells threatened by germs.

In this activity, learners make homemade journals featuring seashell rubbings. First, learners transfer the texture of a seashell onto a piece of paper using a crayon.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners will build a design and build a place for pollinators to drink from.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
