Mixed Bag
What allows the energy from the sun to reach the Earth?
Radiation
Which color will reflect the MOST light and keep you cooler?
White
Different colors of light combine to form what?
White light
A disturbance that sends energy away from the source is called a:
Wave
You are measuring the temperatures at which water boils and freezes. Just to make sure, you take the temperatures a second time. What best describes this?
Repetition
Why do we see lightning flash before we hear thunder?
Light travels faster than sound
Sound travels slower than light
Which color would have the longest wavelength and lowest energy?
Red
What property of light causes waves to bounce?
Reflection
The matter through which some waves travel is called a:
Medium
You conduct an experiment with plants, but you think your results don't make sense. You ask your friend to do the same experiment to see what their results are. What best describes this?
Replication
Sound waves travel the fastest through:
solids
Which color would have the shortest wavelength and highest energy?
Violet
What property of light causes waves to bend? (Hint: think of how a pencil looks in a glass of water)
Refraction
Waves that do not require a medium are called:
Electromagnetic waves
You conduct an experiment five times. What best describes this?
Repetition
When light is refracted, the light:
A. Speeds up
B. Slows down
B. Slows down
You look at an apple and see that its color is red. Why does the apple appear red?
The apple absorbs all colors and reflects red.
Light from the sun travels the fastest in:
Space (vacuum)
The number of waves in given time is:
Frequency
You conduct an experiment and record your data. Another student copies your experiment exactly and gets the same data. What best describes this?
Replication
Kevin is testing to find out if the color of a shirt affects the how hot you feel outside in the sun. He thinks he feels warmer when he wears blue than when he wears white. Before he tests his idea, Kevin makes an inference. Which of the following is the best example of an inference?
A. Blue shirts can be light or dark
B. All darker colors feel warmer than lighter colors
B. All darker colors feel warmer than lighter colors
Which electromagnetic waves are invisible? Name two!
Radio, microwaves, infrared, ultraviolet, x-rays, gamma rays
Light from the sun cannot reach the bottom of the deep ocean. Why does this happen?
The light slows down in the water and is absorbed.
Which wave property is a measure of the distance between two identical points on a wave? (Hint - crest to crest)
Wavelength
Why do scientists repeat experiments many times?
To improve the reliability of their results.
