# Where Will It Go?

### Source Institutions

University of Kansas

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. Use this activity to explain how particle physicists use laws of motion to predict and trace the pathways of subatomic particles that are too small to see.

### Materials List (per group of students)

• Items that you can use as stationary objects including: round cake pan, flat surface made from a thick book, large cookie cutter shapes that can include stars and others. The objects have to be substantial enough so that they are not damaged when hit by the ball. You may need something to weight down the objects as well.
• A pencil
• A ruler and/or meter stick to help roll a ball in a straight line path and to draw incoming and predict outgoing paths
• Small rubber balls (1/2 inch to 1 inch in diameter) that roll easily and will bounce off objects with little damage
• A large piece of paper (at least 12”x18”) beneath the shape makes it easier for learners to gather data as they can draw paths of incoming and outgoing balls
• Masking tape (to tape stationary objects down)
• Colored markers to trace paths of various trials
