Student Exploration: Energy Conversions in a System
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. What are some examples of devices that are powered by batteries?
A calculator, batteries, flashlight
2. What different forms of energy are demonstrated by these devices?
Most of them demonstrate kinetic or electrical energy
Gizmos Warm Up
Energy constantly changes from one form to another, but in a
closed system, the total amount of energy always remains the
same. This concept is known formally as the law of conservation
of energy.
The Energy Conversion in a System Gizmo allows you to observe
the law of conservation of energy in action. In the Gizmo, a
suspended cylinder has gravitational potential energy. When the
cylinder is released, the gravitational potential energy is converted
into kinetic energy, which causes the stirrer in the water to spin.
1. What is the initial temperature (T) of the water?
25 celsius
2. Click Play ( ). What happens as the cylinder drops?
The temperature increases and the cylinder decreases in height as it lowers from the original
position in mid air.
3. What is the final temperature of the water?
29.69 celsius
4. Why do you think the temperature of the water increased?
I think that the movement created by the little turbine fan within the beaker transferred more kinetic
energy which adds heat energy to the water.
