Instructor Information
Topic: Electricity Safety & History
Objective:
Cover electricity rules before starting activities.
Test students knowledge of early electrical technology
Summary:
Establishing safety rules is very important and can help keep students from playing with the equipment and materials. A more light hearted topic is changed to early electrical inventions. Students are asked to guess what type of inventions were introduced prior to 1910.

2. Topic: Future Challenges
Methodology:
Discussion leading to questioning. Students provide details to basic information provided.
Differentiation:
Variation of questions to students

5. Boston Science Museum
The plasma ball was presented to the students the prior day and a larger version is shown at the Boston Science Museum in the picture above.

6. Safety with Electricity
Don’t put anything into outlets
The outlets are 110 Volts and 15 Amps and can kill you.
Special electrical equipment is needed to test
Don’t touch bare wires
Water and Electricity don’t Mix
Spills can conduct electricity so don’t put drinks near electronics and don’t put electronics near water
Wires can become hot so be careful when holding them

7. Electricity in History
Attractive Force was studied in ancient times
Revealed that static electricity goes to the “Ground”
If person is insulated from the ground then they can store a charge
This led to the study of insulators and conductors
The study of lightning had a fair number of failures
Later the development of batteries, light bulbs and motors would change how people live.

8. Earliest ‘Electricians’
Benjamin Franklin suspected that Lightning and Electricity were the same.
Franklin invented the lightning rod as a way of protecting houses, ships, and people.
