In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

In this activity, learners discover that some things only stand up while they are spinning.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners discover that sand is the major ingredient in glass.

Build a house you can fit inside, using cardboard tubes.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this story time program, young learners listen to the Dr.
