The ability to do work
What is energy?

Renewable resources include those that are always constant because they can be renewed and used again. Non-renewable resources consist of materials that can't be used again and would therefore cease to exist in the future.
What is the difference between renewable and non-renewable resources? What makes them renewable/non-renewable?
100
Solar power is using the sun's thermal energy to create power.
What is solar power?
100
A disturbance that travels through a medium from one location to another
What is a wave?
100
When waves pass through a substance
What is transmission?
200
KE=(0.5)(m)(v)(v)
m= mass
v= speed
What is the formula for kinetic energy?
200
Solar, Eolic, Geothermal, Hydroelectric, Wave, Tide
Name all the types of renewable resources
200
Because black absorbs light, so it will bring the heat into the box
Why is black a good material to use in a solar cooker?
200
Disturbance: a change or movement
Medium: substance through which the wave travels
What are disturbances and mediums in a wave?
200
When waves are taken into a substance or material
What is absorption?
300
Kinetic, potential, mechanical, sound, chemical, radiant, electric, nuclear, thermal
Name all types of energies
300
Since they are always there, we can make a good use of them and gain a lot of money by harnessing the tide's power
What is a positive economical outcome of tidal resources?
300
Black paper/lining, aluminum foil(or any type of reflective surface), transparent cellophane paper, and thick cardboard for the box.
Name the key materials to make a basic solar oven.
300
Crest: The highest point in a wave. Trough: The lowest point in a wave. Period: The time it takes for a full cycle in a wave. Frequency: The number of cycles in 1 second. Amplitude: The distance between the lowest and highest point
Name all the parts of a wave and, in general words, their definition.
300
When a wave bounces off a material
What is reflection?
400
[Answers may vary] The mass doesn't affect the speed directly. It only determines how quickly an object can change speed under the action of the given force.
How does the mass of an object affect its speed?
400
They might get in the way of people, the noise of wind turbines could be too loud, and they cost a lot of money.
What is a negative outcome of using eolic resources?
400
We harness the sun's heat into a box that should absorb light and retain it, then concentrate the heat into the center to cook the food.
How do we use the sun to cook?
400
Transverse: The medium is perpendicular to the direction that the wave is going. Longitudinal: Medium is parallel to the direction of the wave.
What's the difference between a transverse wave and a longitudinal wave?
400
Light transmission because the light went in through one side and passed through the glass to make the fire.
Lily is trying to make a fire. The sun is very bright and she happens to have a magnifying glass. She angles the glass and catches the sun beam well enough to create a small fire. What type of wave characteristic was that? How do you know?
500
[Answers may vary] Potential energy is the stored energy in an object while the kinetic energy of an object is relative to other moving objects in its environment.
Note: Potential energy is not relative to the environment of an object.
What is the difference between kinetic and potential energy?
500
Sample Answer: Solar Power is used to harness the sun's heat and create energy. We can put these solar panels on roofs and connect them directly to power sources.
What is an example of a renewable resource and in what form might it be used?
500
1. She can check the angles in which she is placing the reflecting aluminum foil. 2. She can use a thicker cardboard to mantain the heat inside
Anna is making a solar cooker. She has a thin cardboard box, black construction paper, and aluminum foil. But when she tries it out, the heat isn't strong enough to cook. How can she fix it?
500
Longitudinal
Lewis is listening to music. What type of wave is in practice here?
500
Sound reflection because he used the sides of a cup to reflect the sound and make it louder.
James is listening to music with his phone, but the volume is too low. To make it louder, he places the phone inside a cup. The music sounds a bit echo-y, but it's definitely louder. What wave characteristic is that and how do you know?
