Objectives

The student will be able to predict the outcome of two
objects colliding.

The student will be able to conduct a scientific experiment to
discover energy transfer.
+
Children’s Ideas On Science

Children often have the misconception that energy is
found in living things only.


In this lesson, students will learn that inanimate objects
posses energy as well.
They will observe and make predictions about the changes
in the energy of a marble as it rolls down a ramp and
collides with another marble.

Vocabulary

Energy- ability to do work

Law of Conservation of Energy- energy cannot be created
nor destroyed, but it can be transferred to another object

Collision- when two objects bump into each other and the
energy is transferred from one object to the other

Position- location of an object in space

Speed- distance an object travels in a certain amount of time

Questions

How did colliding the marbles at different heights affect the
distance that the stationary marble traveled?

Based on what you know now, how would you explain how
energy changes when objects collide?
