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.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

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 activity, learners explore why animals, specifically dinosaurs, live in families.

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, 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 will repurpose an old t-shirt to create their own yarn or string.

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

In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

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 use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

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 craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.
