waves
Science used Boombox in the Gallery
CLUE #1
X-rays did not cause the injury.
Short wavelengths and low frequency
Mrs. Fink was doing jumping jacks in the Exploratorium.
Long wavelengths and low frequency
The injury was not committed using a slinky.
Long wavelengths and high frequency
Mrs. Unrath was adding baking soda to vingar in the Wing of Innovation.
Short wavelengths and high frequency
What are 2 characteristics of waves with low energy?
CLUE #2
Mr. Bogdan was reading Tolkien in the Discovery Center.
Medium
Ms. Heckman was solving algebra puzzles in the Gallery of Science.
Frequency
The victim did not have a gamma radiation.
Amplitude
A slinky was not found near the victim.
Wavelength
Which of the following does NOT describe the energy of waves?
CLUE #3
speeding up, or slowing down
Mrs. Unrath was making a volcano in the Gallery of Science.
It’s speed is constant if the source is stationary,
The victim did not have a gamma radiation.
It’s speed will speed up if the source is speeding up and slow down when the source slows
Ms. Benton was reenacting WWII in the Wing of Innovation.
It’s speed will slow down if the source is speeding up and go faster if the sources speeds up
stationary then it slows down.
A slinky was not used on the victim.
It speeds up steadily until the source becomes
Which is true about light?
CLUE #4
Mrs. Unrath was freezing marshmallows in the National Hall of STEM.
It would stop moving
The victim was not exposed to gamma rays.
It would decrease
The victim’s did not succumb to x-rays.
It would increase
Mr. Hinshaw was walking his snake in the Exploratorium.
It remains constant
If a wave is traveling at a constant speed, and the frequency increases, what would happen to the wavelength?
The victim had not been x-rayed.
Magnetic model
The victim was not near a lamp.
Wave model
Mrs. Unrath wasbuilding an atom the Institute of Enlightenment.
Electric model

Light can travel in a vacuum or in air
Mr. Hinshaw was singing to birds in the National Hall
The injury did not involve a lamp.
Light needs a solid medium to travel
The victim was not deafened by a boombox.
Light needs a liquid medium to travel

Innovation.
The frequency decreases, and the pitch increases.
Enlightenment. Ms. Heckman was counting cubes in the Wing of
The frequency decreases, and the pitch decreases
Mrs. Fink was doing laps in the Institute of
The victim was not knocked by a wave.
The frequency increases, and the pitch increases
The victim was not exposed to a boombox.
The frequency increases, and the pitch decreases
What happens to the frequency and pitch of a siren as it approaches you?

Wave Model
pitch of the horn increases. This is known as the
A car blows its horn as it travels towards you, and you recognize the
The Doppler effect is a change in the sound or light waves when the source of the waves is moving. It was discovered by a scientist named Christian Doppler in 1842. One example of the Doppler effect is when a vehicle with a siren approaches and then passes by. The sound of the siren sounds higher as it gets closer and lower as it moves away. When the source of the sound wave is moving towards you, the time between each wave is shorter, so the frequency is higher. But when the source is moving away from you, the time between each wave is longer, so the frequency is lower. This is because each wave is emitted from a position closer or farther from you than the previous wave. The Doppler effect is used in many different fields of science. Astronomers use it to detect planets outside of our solar system, called exoplanets. They can tell if a star is moving towards or away from us by looking at the changes in its spectrum, which is the colors of light it emits. By studying these changes, scientists can learn more about the planets and stars in our universe. So, the Doppler effect is a cool scientific discovery that helps us understand how sound and light waves change when the source is moving. It can be seen in everyday life, like when a siren gets louder and then quieter as a vehicle passes by. And it's also used by scientists to learn more about the stars and planets in our universe.
Light is a special kind of energy that travels in waves. It can travel through empty space, like in outer space. Light travels really, really fast - even faster than sound! In just one second, light can go around the Earth seven and a half times. That's super fast! When we see the Sun, we're actually seeing what it looked like over 8 minutes ago because that's how long it takes for light to reach us from the Sun. Light always moves in straight lines until it hits something. That's why shadows are formed when light is blocked by an object. Shadows don't look completely dark because some light still gets around the object. Light can also travel through different things, like air, glass, and even mirrors. When light passes through different materials, it can change direction, but it still moves in a straight line called a ray. Light can also behave like particles called photons. These particles are really tiny and they move really fast. Light can also spread out as it travels, which is called diffraction. This is why sometimes you see spikes of light attached to stars in pictures. Scientists are still learning a lot about light and how it works, but it's really amazing how it can travel so fast and in straight lines!
