The system was made of:

1. 3 wires

2. 2 alligator clips

3. 1 battery

4. 1 light bulb and holder

5. 1 light switch and holder

Draw, color and label this SERIES CIRCUIT system in your notebook. 

Write and answer these 6 questions in your notebook.

  1. List at least 2 inputs.
  2. List at least 2 outputs.
  3. The energy that turns the light bulb on is coming from
  4. Chemical energy from the ? is transferred into ? energy
    and ? energy.
  5. The model used is ??.
  6. The boundaries of the system are: ?

Draw, color and label this PARALLEL CIRCUIT system in your notebook

TASK 3 WORD BANK AND DEFINITIONS

Match the 6 terms with the definitions:

TERMS-
Models – Outputs – System – Inputs – Energy- Boundary

DEFINITIONS-

1. _______All of the items included in a System

2.________ A collection of objects that interact and/or influence one another. These objects often work together to answer a question or solve a problem. They are often represented by models, which uses boundaries, inputs, and outputs to describe what is and is not part of this. (e.g., the electric generator can be considered in this).

3._________Anything that goes into the system from outside its boundary (e.g., energy supplied by one’s hand to turn the nail and the magnets in the electric generator).

4. ______Anything that crosses the boundary to leave the system (e.g., light energy produced by the bulb and powered by the electric generator).

5. ________Something needed to cause change

6. ________ Simplified representations of systems, objects, ideas, processes, and/or phenomena that help scientists describe, explain, and make predictions. All of these have limitations and built-in inaccuracies that scientists need to be aware of.
