In this math lesson, learners count and compare amounts of money less than or equal to one dollar.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

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

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this math activity (Page 12 of the Play Ball! PDF), learners play a game of "soccer" and analyze the results of the game.

In this activity, learners investigate the properties of different types of balls.

In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.

In this math activity (Page 14 of the Play Ball! PDF), learners play a game of "basketball" and analyze the results of the game.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.
