Opposite poles attract. Like poles repel. Force is dependent on distance
What are the characteristics of magnets?
Attraction of a magnet for another object.
What does magnetism have to do with electricity?
What is it creates a magnetic field?
When magnets are further apart, what happens to the magnetic field?
It grows weaker.
When magnets get closer together, what happens to the magnetic field?
It grows stronger.
Copper Aluminum Platinum Gold Silver Water People and Animals Trees
What are conductors?
Glass Porcelain Plastic Rubber
What are insulators?
Why are humans a good conductor of electricity?
Electricity will always take the shortest path to the ground. Your body is 60% water and that makes you a good conductor of electricity. If a power line has fallen on a tree and you touch the tree you become the path or conductor to the ground and could get electrocuted.
Why do we use insulators on wires?
The rubber or plastic on an electrical cord provides an insulator for the wires. By covering the wires, the electricity cannot go through the rubber and is forced to follow the path on the aluminum or copper wires.
Energy comes from:
What is a power source?
In a circuit, why are the wires made of copper?
Explain which circuit will have brighter light and why:
Circuit 1 will have brighter light because it has to transfer energy into 2 light bulbs and circuit 2 has to light 3 bulbs.
Explain the difference between a series circuit and a parallel circuit.
In a series circuit, the energy only has one way to travel. In a parallel circuit, the energy can go more than one way.
Explain what happens if one of the bulbs burn out.
The other bulb will be brighter because it will get all of the electricity.
Energy is transferred from a power source and then it can power a light bulb, a sound, and produce heat?
Why does a circuit work?
Margaret Mead
anthropologist, writer, scientist; environmentalist, women's rights advocate, studied tribes in India
Nikola Tesla
The "Tesla coil," Tesla also invented fluorescent lights and a new type of steam turbine, and he became increasingly intrigued with the wireless transmission of power.
Michael Faraday
British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. His biggest breakthrough in electricity was his invention of the electric motor
Benjamin Franklin
Bifocals Electricity Lightening Rod Printing Press Stove Odometer
What is: astronaut teacher doctor dentist surgeon pharmacist environmental worker vet orthopedic orthodontist science and engineering worker gardener scientist archeologist
Temperature changes from day to night It is a line graph and shows change over time.
Using this table can you tell what happens to the electromagnet when you add more loops?
If I wanted to compare how many kids buy lunch for each day of the week, what kind of graph would I use?
Bar Graph School Lunch 1200 1000 Number of Students Buying 800 600 400 200 0 Monday Tuesday Wednesday Thursday Friday Day of the Week
If I wanted to show the percentage of students buying lunches what kind of graph would I use?
Pie Graph School Lunches 15% 26% 18% 12% 29% Monday Tuesday Wednesday Thursday Friday
