We built a working electric generator in a previous class. Today, we will need to learn some new vocab to apply to this generator model and continue to grow our understanding of how electricity is made.
Video link - Here is a simple generator model that is a lot like the one we created in class together, in case you need to review how this works!
REVIEW: Think back to our generator building activity from our previous class. What were the most important components or parts of the generator we built in class?
REVIEW: How could we get the light bulb to be BRIGHTER?
Some important vocab words to know:
System- A collection of objects that interact and/or influence one another. These objects often work together to solve a problem. Systems are often represented by models.
Inputs- Anything that goes into the system from outside its boundary.
Outputs- Anything that crosses the boundary to leave the system.
Energy- Something needed to cause change.
Models- Simplified representations of systems, objects, ideas and processes that help scientists describe, explain, and make predictions.
Boundary - Limits to a system (physical space or how it works).
Label the generator shown in this picture with these words:
1. Generator Case
2. Coil of Wire
3. Two Wire Ends (of Coil)
4. Two Leads (to Light Bulb)
5. Light Bulb
6. Magnets
7. Nail
What is the INPUT of this generator system?
What is the OUTPUT of this generator system?
What are the BOUNDARIES of this generator system?
Where is energy present in the generator system?
What is happening to make the light bulb light up?
Review your Unit Challenge scenario for this unit.
Review your energy cards from Lesson 2, specifically focusing on wind power and hydroelectric power.
What questions do you still have about this generator, the Unit Challenge scenario, or the energy cards?
