The highest part of a wave is called
The crest
100
What is the term that means "a PUSH or a PULL on an object"
Force
100
True or false:
An example of light energy would be a printer producing paper copies when plugged into an outlet.
False:
That is an example of electrical energy.
100
True or false:
Alternative energy sources were formed millions of years ago from long-dead plants and animals.
False:
This defines fossil fuels.
100
What are the five senses that animals have?
Sight, smell, touch, taste, and hearing.
200
Which wave shows a HIGH frequency?
A (left) or B (right)
Wave B (right):
200
When does the rollercoaster have the highest potential energy?
Point A
200
True or False:
Energy cannot be created or destroyed - it can only change forms/types.
True
200
List all three fossil fuels
Coal, oil (petroleum), natural gas
200
What is the main function of a bird's beak?
To obtain food from its environment.
300
What part of the wave measures how loud or soft a sound is?
Amplitude
300
Describe the energy transformation taking place:
The hand has kinetic (motion) energy. When it hits the dominos that have potential (stored) energy, then the kinetic energy will transfer to the dominos, making them move.
300
What are the 6 types of energy?
Light, Sound, Heat, Electrical, Chemical, Mechanical
300
What are the 5 types of alternative energy?
Solar energy (sun), Wind energy (wind), Hydroelectric energy (water), Geothermal energy (earth's heat), and Biomass energy (plant/animal matter)
300
Which plant part moves the water and nutrients throughout the plant in order to help it survive?
The stem
400
What does each letter represent in the sound wave below?
A: Trough
B: Amplitude
C: Crest
D: Wavelength
400
Describe the flow of energy in the circuit below:
The energy will travel from the battery through the wire to the lightbulb. It will continue from the wire to the closed switch, then through the wire back to the battery.
400
Define mechanical energy and give an example of an object with mechanical energy.
Mechanical energy is all of the potential and kinetic energy within an object. Examples include fans, a bow and arrow, airplanes, humans, etc.
400
What are some advantages of renewable energy resources?
They can be reused, they are cleaner (nonpolluting), most are readily available/able to harvest (sun, wind, water, etc.).
400
Which renewable energy resource can have a negative impact on wildlife?
Windmills -- their large blades can harm birds; or Hydropower plants -- creating a dam for stored water can harm traveling fish or disrupt the wildlife.
500
Draw a wave that shows a low amplitude and a high frequency.
The wave should be drawn low (quiet) and close together (fast).
500
When objects collide, some energy is transformed into _______ and ________ energy.
Sound and heat energy.
500
What type of energy is stored in a stretched out rubber band? How do you know?
Potential energy. The rubber band isn't moving, but it has the potential to if the person lets go of one side.
500
Where does nuclear energy come from? Is it renewable or nonrenewable?
Nonrenewable energy: it comes from breaking the atoms of uranium, a limited resource on earth that cannot be replaced once used up.
500
What are the plant's male reproductive parts called? What is produced at the male plant parts?
The stamen is made up of the filament and anthers. This is where pollen is produced.
