The who, where, and how

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. Smith 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

Ms. Ryder was reading Tolkien in the Discovery Center.

Medium

Ms. Young was solving algebra puzzles in the Gallery of Science.

Frequency

The victim did not have a gamma radiation.

Amplitude

Wavelength

Which of the following does NOT describe the energy of waves?

CLUE #3

speeding up, or slowing down

Mrs. Smith 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. Becker 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

CLUE #4

Mrs. Smith 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.

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

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?

CLUE #10

Ms. Young was graphing equations in the Institute of Enlightenment.

Dopper Effect

The injury was not from a boombox.

Law of Motion

Ms. Becker was drawing the state borders in the Wing of Innovation.

Photoelectric Effect

The victim was not knocked by a wave.

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!
