We talked a couple of weeks ago about power outages. As a result of any power outages that you have experienced, what changes did you make — such as gathering an emergency kit or formulating an emergency plan for next time?
How do we rely on electricity? Would you say we rely on it or do we NEED it? Explain your thoughts.
Categorize them into conveniences or necessities
Respond to the following questions.
What energy conveniences take place inside electric appliances?
Explain how, with electricity, input energy is always greater than useful output energy.
Why is it important to conserve electric energy?
How can you reduce the monthly electric bill in your home?
Here are two links to help understand the high costs of electricity and what the Alberta government is trying to do in their Affordability Action Plan.
What are some of the difficulties they may encounter?
What are the benefits?
We rely on electricity not only for survival, but for much of our entertainment, such as powering televisions, game consoles, recharging our cell phones, etc.
Do you know of places that do not have access to electricity? What do you think they do for entertainment?
Many parts of the world do not have access to electric power because it is not available to them. However, they still manage to cook, clean, and survive.
To get an idea of what countries use what sources of electyricity generation, review this link. Some parts are interactive so you can check out individual data by hovering over some of the graphs.
Spend some time reviewing this site to get an idea of how Canada contributes to global greenhouse gas production by the use of fossil fuel generating plants.
Where does electricity come from?
Where does electricity come from?
Electricity has been around for more than 200 years, but it has been in nature forever. It wasn’t until they discovered how to make electricity that it became a regular part of our lives.
History of Electricity
History of Electricity
Benjamin Franklin and Michael Faraday are two scientists who had been investigating the idea of electricity based on theories they had.
In 1752, Franklin after proves that there are positive and negative electrons by flying his kite in a storm. Contrary to popular belief, Franklin did not fly his kite and get hit by lightning. Instead, he flew his kite using a silk string that helped to insulate him, and became a ground wire of atmospheric circuit. The key that was hanging on the kite string became negatively charged by the electrons that were on the string. As Franklin put his hand near the string, sparks were produced between his hand and the key.
Through this experiment, Benjamin Franklin was able to find evidence for the new terms he coined:
Battery, conductor, condenser, charge, discharge, plus, minus, and electric shock.
