Energy Types
What type of energy does a moving car have?
Kinetic energy
True or False: Energy can be created from nothing.
False
In all energy-capturing devices, what TWO types of energy does the generator convert between?
Kinetic and electrical
"The grass is wet" - Is this an observation or an inference?
Observation
Why does the rescue team need energy-capturing devices?
To have power during emergencies/power outages (also acceptable: when the power is out, during emergencies, in remote locations)
If you can hear it, what type of energy does it have?
Sound energy
When energy moves from one object to another, this is called energy _______.
Transfer
Your phone gets warm when it's charging. What does this tell you about energy conversion?
Some energy is being converted to heat/thermal energy (also acceptable: energy is being lost as heat, not all energy converts perfectly, some energy becomes heat)
"It rained last night" (based on wet grass) - Is this an observation or an inference?
Inference
What resource are solar panels, wind turbines, and water power examples of?
Renewable resources (also acceptable: renewable energy)
A charged battery has what type of energy stored inside?
Potential energy
(also chemical potential energy)
When a toaster changes electrical energy into heat energy, this is called energy _______.
Conversion
Why can't a device capture 100% of your motion energy and convert it all to electricity?
Some energy is always lost as heat/sound/friction (also acceptable: energy is lost to heat, energy loss, not 100% efficient)
An observation uses your 5 _______.
Senses
What is the FIRST step in the energy transfer pattern? (Human _____ → Kinetic → Generator → Electrical)
Potential energy (also acceptable: chemical potential energy)
What are the TWO main categories that all energy can be grouped into?
Kinetic and Potential
When you bounce a ball, it doesn't bounce back as high as you dropped it. Where did the "lost" energy go?
It converted to sound energy and heat energy. (also acceptable: sound and heat, or thermal energy and sound)
A fan is plugged into the wall. Trace the energy conversions from the outlet to the moving air. (At least 2 conversions)
Electrical energy → kinetic energy (motor spinning) → kinetic energy (air moving) OR Electrical → kinetic → motion of air
What are the THREE parts of a scientific argument?
Claim, Evidence, Reasoning (must have all three, any order acceptable)
Name TWO specific situations or locations where rescue workers cannot access regular power outlets.
During storms/power outages, in wilderness/remote areas, in dark tunnels, during natural disasters, in collapsed buildings
Name THREE different types of energy you can observe from a burning candle.
Light, Heat, and Sound
In the hand-crank flashlight, what THREE forms of energy are involved in order?
Kinetic, Electrical, Light
If you built a device that captures energy from students walking up stairs at school, where in the energy transfer pattern would the students' leg muscles fit?
At the very beginning/first step - they provide the human motion (also acceptable: source of motion, human motion step, beginning of pattern, where kinetic energy starts)
A student sees a hand-crank flashlight turn on and claims it has energy. What would be good REASONING to connect this evidence to the claim?
"This matters because the light turning on shows that energy is present. When the crank turned, it created kinetic energy that was converted to electrical energy, which powered the light. This proves the flashlight has energy."
Put these in the correct order for energy-capturing devices: Battery Storage, Electrical Energy, Generator, Kinetic Energy, Human Motion
Human Motion → Kinetic Energy → Generator → Electrical Energy → Battery Storage
