The ability to make things move or change...
What is ENERGY?
To absorb is...
What is TO TAKE IN ENERGY?
A wave is best described as...
What is A PATTERN THAT DESCRIBES HOW ENERGY IS CARRIED FROM ONE PLACE TO ANOTHER?
This substance in skin helps protect cells.
What is MELANIN?
To emit is...
What is TO GIVE OFF?
Something that carries energy from one place to another...
What is LIGHT?
To reflect is...
What is TO BOUNCE OFF WITHOUT ABSORBING?
True OR False
Light is a type of wave that carries energy from place to place, except through empty space.
What is FALSE?
True OR False
Infrared light from the sun is most linked to skin damage.
What is FALSE?
(Ultraviolet light)
What is a light source?
What is AN OBJECT THAT EMITS LIGHT?
What is OBSERVING THE CHANGES ENERGY CAUSES TO MATTER?
If light transmitted, what does that mean?
What is IT PASSED THROUGH?
A wavelength is...
What is THE DISTANCE FROM ONE PEAK OF A WAVE TO THE NEXT?
Why does melanin reduce the risk of skin cancer?
What is IT ABSORBS THE ULTRAVIOLET LIGHT BEFORE IT CAN DAMAGE SKIN CELLS?
An ultraviolet light causes a chemical change that visible light sometimes cannot. Why?
What is DIFFERENT TYPES OF LIGHT CAN CHANGE A MATERIAL IN DIFFERENT WAYS?
Why can light cause materials to change even though light has no mass?
What is LIGHT CARRIES ENERGY?
True OR FALSE.
A material becomes warmer after light hits it. The material reflected the light.
What is FALSE?
Is it possible for a light source to emit more than one type of light?
A: Only one type of light
B: More than one type of light
In a skin cancer model, what happens after ultraviolet light is absorbed by skin cells?
What is THE ENERGY DAMAGES THE DNA/GENETIC MATERIAL?
A material appears red because it reflects red light and ______ other colors.
A material gets warmer after light hits it. What does this tell you about what the light did?
What is THE LIGHT TRANSFERRED ENERGY INTO THE MATERIAL?
Infrared light is absorbed by a material, while visible light is reflected.
Which of the types of light can cause a change? Why?
What is INFRARED LIGHT?
What is THE INFRARED LIGHT WAS ABSORBED BY THE MATERIAL CAUSING A CHANGE?
If there are two different types of lights, that means they also have...
What is DIFFERENT WAVELENGTHS?
Think about our modeling tool of light's effect on skin. Explain the path that causes sunlight to lead to skin cancer.
What is THE LIGHT FROM THE SUN TRANSFERS/CARRIES ENERGY TO THE GENETIC MATERIAL AND THE GENETIC MATERIAL ABSORBS THE ENERGY, WHICH DAMAGES THE SKIN CELLS.
A material absorbs infrared light but transmits X-rays. Which light could cause melting and why?
What is INFRARED LIGHT BECAUSE THE MATERIAL ABSORBED THAT TYPE;
What is WHEN LIGHT ENERGY IS ABSORBED IT TRANSFERS ENERGY INTO THE MATERIAL?
