1. Science
Activity: Stnd 01
Date
Standard 01: 8.PS2.1 Magnetism and Electricity
Design and conduct an investigation about magnetism and electricity. Examine factors that increase or diminish the electric current and the magnetic field strength.
Key Focus: Science and Engineering Practice(s)
Develop and Use Models
Key Focus: Crosscutting Concept
Recognize cause and effect relationships
1st Investigation: Construct and test an electromagnet
2nd Investigation: Do an electromagnetic induction simulation.
3rd Investigation: Construct and test an electrical motor

2. (Generating Electricity)
Electromagnetic Induction
(Generating Electricity)
These devices are commonly called generators.
Magnets and a coil of wire can induce (generate) electricity
The magnet has to move through the coil (solenoid)
… or the coil has to move through the magnet.
To Increase/Decrease the Electrical Current:
(1) Move it faster or slower (2) Add or remove coils.

3. Construct an Electrical Generator
