The teacher will perform the "bouncing ball" experiment. Dropping a tennis ball on a basketball will cause the tennis ball to bounce off the basketball and fly high into the air. The two balls hit each other just after they hit the ground and a lot of the kinetic energy in the basketball is transferred through to the smaller tennis bal which will cause it to fly high into the air.
The teacher will ask the students why the tennis ball ended up flying up higher? Students will work toward the idea that the energy from the basketball was transferred to the tennis ball.
2 Direct Instruction
The teacher will remind students that energy can be stored in food, fuel, and batteries and it can be converted from one form to another. But how does it move from one place to another? How does energy get from a battery to a motor?
3 Guided Practice
The stations that students will complete will be similar to the ones from the previous lesson, only this time the focus will be on the way the energy moved. Students will fill out a sheet during their stations that they access in Schoology and open via Notability. Students will take a screenshot of thier work so they have a saved copy of it. The stations include the following: Station 1: A Spring Toy, Station 2: Bowling, Station 3: Tone Generator, Station 4: Battery and Motor
Students will be answering the following questions:
Where did the energy come from?
Where did the energy go?
What did the energy make happen?
How did the energy get from point A to point B?
After the stations are finished, the whole class will discuss the results of each station.
4 Independent Practice
Students will think of a way that energy is transfered from one form to the other (like the bouncing ball demonstration). They can research different energy transfer experiments on the Internet. With a partner, they will record themselves demonstrating an example of energy transfer and will post it to the Schoology album titled Examples of Energy Transfer. Students will access directions from Schoology, they are also listed below.
Directions for Energy Transfer Demonstration:
With a partner, you will research and demonstrate and example of energy transfer.
Find an example of energy transfer.
Determine how you will demonstrate it.
Video tape you and your partner demonstrating the example of energy transfer.
Use your voice to describe what is occurring.
You will be assessed on the following:
Choice of Energy Transfer
4- The example of energy transfer is correct.
3- The example of energy transfer is correct.
2- The example of energy transfer is not correct.
1- The example of energy transfer is not correct.
4- The demonstration of energy transfer was easy to understand, watch, and hear.
3- The demonstration of energy transfer included two of the following: was easy to understand, watch, and hear.
2- The demonstration of energy transfer included one of the following: was easy to understand, watch, and hear..
1- The demonstration of energy transfer did not include any of the following: easy to understand, watch, and hear.
Students will watch a demonstration of a ping pong ball in a basin of water. The ball will move when the water becomes wavy. Students will take a picture with their iPads of the demonstration and will annotate it using Skitch to show their knowledge of energy transfer. Students will upload these pictures to Schoology under Water and Ping Pong Ball Experiment.
