In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this cooperative game, learners devise strategies about sharing a small space with each other.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity, learners explore dinosaur fossils and a dig site. Learners work in groups to analyze a dig site map and match bones to a skeletal drawing of Kelsey (a Triceratops).

In this activity, learners explore how dinosaurs are named and what their names mean. Learners listen to "The Littlest Dinosaurs" by Bernard Most.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In "Exploring the Universe: Exoplanet Transits," participants simulate one of the methods scientists use to discover planets orbiting distant stars.

In this activity, learners explore the physics of impact craters from their own backyard using mud. Learners are encouraged to match features of real impact craters to their models.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

This demonstration activity models how Venus appears from Earth.

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

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
