In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

In this three-day lesson, learners identify two-dimensional shapes used in castle construction, create a castle collage using assorted shapes, and design tapestries using repeated patterns of color, s
