Heat Transfer
A metal spoon becomes hot after sitting in a pot of hot soup. What type of heat transfer is occurring?
What is Conduction
These lights charge during the day and turn on at night without being plugged into a wall outlet. Which renewable resource provides their energy?
What is Solar Energy
I change wood into thermal, sound and light energy.
If I am at the top of the roller coaster, what kind of Kinetic Energy do I have?
What is low to no kinetic energy
I transfer chemical to electrical to light. What am I?
What is a Flashlight
What energy is used when a heat lamp is on baby chickens in a shed?
What is Radiation
A mill uses a wheel turned by flowing river water to grind grain into flour. Which renewable resource supplies the energy?
What is water energy
During an earthquake, the ground vibrates and sends seismic waves through Earth. When these vibrations reach buildings, they may cause windows to rattle and objects to vibrate. What kind of energy am I causing?
If I am at the bottom of the hill I have my most what?
What are the 3 energies formed in a campfire?
What is Thermal, Sound, and Light
You feel the warmth of the Sun on your skin even though space between Earth and the Sun is mostly empty. How is the heat transferred?
What is Radiation
Electricity used to charge a calculator with a small photovoltaic cell
What is solar energy
Inside the Sun, hydrogen nuclei combine to form helium, releasing enormous amounts of energy that eventually reaches Earth as heat and light. What type of energy is released during this process?
What is Nuclear energy
As I am going up the roller coaster, I am building what kind of energy?
I cannot be created or destroyed, I am transformed or transferred
A student heats water in a pot on a stove. Explain why the water at the bottom rises and the cooler water near the top sinks.
What is heated water expands, becomes less dense, and rises. Cooler, denser water sinks, creating a convection current.
A farmer uses a windmill to pump water from an underground well into a storage tank for the farm's animals. Which renewable resource provides the energy to operate the pump?
What is wind
A student eats a snack before running a race. The student's body uses the stored energy in the food to move muscles and release heat. Identify the original energy type in the food and the two energy types produced during the activity.
What is Chemical energy and what is mechanical energy and thermal energy.
A roller coaster car is moving upward along the track toward the top of a hill. As it climbs, its speed decreases. What happens to its gravitational potential energy?
I go from mechanical to an inverter to a generator from wind.
Water at the bottom of a pot heats up, becomes less dense, and rises while cooler water sinks. What type of heat transfer is happening?
What is Convection
My car can run on a renewable resource made from corn, what renewable resource am I?
What is Ethanol
An astronaut strikes a metal tool outside a spacecraft while floating in the vacuum of space. Why would another astronaut nearby not hear the strike through the empty space between them?
Sound requires a medium, such as air, water, or a solid, to travel. A vacuum has no particles to transmit the sound waves.
During a volcanic eruption, a large rock is launched upward into the air. As the rock rises and slows down, what happens to its gravitational potential energy and kinetic energy?
Gravitational potential energy increases, and kinetic energy decreases.
I kind of energy can bring on a tsunami?
What is convection energy.
