In our storyboard, we are illustrating what activities as well as forms of energy we use on a typical school day from waking up until arriving at school.
Taking a Shower
Brushing Your Teeth
When we make our breakfast, chemical PE stored in our muscles is transferred to mechanical energy. Once we start to chew the food, mechanical energy is moving our jaws and chemical energy is breaking down the food using saliva. The digestion of food uses chemical energy and results in chemical PE.
Wiping Ice Off the Car
The electrical energy from a power plant is transferred to thermal energy in a water heater which heats up the temperature of the water in the shower. Then, chemical PE stored in our muscles is converted to mechanical energy when we wash, rinse, and dry ourselves.
Driving to School
Next, electrical energy in the battery of the electrical toothbrush is transferred to mechanical energy to enable the motion of the bristles as well as sound energy. Chemical PE stored in our muscles is also converted to mechanical energy to move the toothbrush around in our mouths.
Main Sources of Energy
1. Chemical Energy- chemical reactions 2. Mechanical Energy- machines and muscles3. Electrical Energy- Coal and nuclear power plants4. Thermal/Heat Energy- Sun, heater/furnace
The electrical energy in the car battery is transferred to thermal energy in the window heaters so that the ice can melt and be easily scraped off the car. Afterwards, chemical PE stored in our muscles is converted to mechanical energy when we manually scrape the ice off of the car.
The electrical energy in the car battery is needed to start the car, turn the lights on, and play the radio. In addition, some electrical energy is transferred to chemical energy to burn the gasoline (combustion) well as mechanical energy to rotate the car's wheels and get the car moving.
On my honor, I have not received, given, nor will I give any unauthorized aid on this assignment. X Kendyl George and Aden Lemma
