EMS Identification
Which EMS wave can be used in meteorology?
Infrared
Refer to the chart on the board. Which magnet picked up the most paperclips?
Magnet U
Light waves travel fastest in _____________.
Empty space / vacuum
Which type of EMS wave do we use if we need to see a broken bone?
X-ray
How many inches long is a baby kangaroo at birth?
one inch
Which EMS wave can be used to both treat and cause cancer?
Gamma
Refer to the chart on the board. Why did magnet T pick up less paperclips?
It was held farther away from the paperclips.
When an ultraviolet wave travels from empty space to the air in the Earth's atmosphere, what happens to it's speed?
It slows down
Which type of EMS wave do we use for listening to music on a station?
Radio wave
Even a small amount of this liquid placed on a scorpion will make it go crazy and sting itself to death.
Alcohol
Which EMS wave has the highest energy?
Gamma
Magnet X is held 1 inch away from a pile of paperclips, and picks up 5 paperclips. Magnet Y is held 1/2 inch away from a pile of paperclips, and picks up 10 paperclips. What conclusion can you make about the relationship between distance and magnet strength?
The closer the magnet is to an object, the stronger the magnetic pull.
Why do you lose certain radio stations (especially FM) the farther you move away from it?
Which type or types of EMS wave(s) do we use to disinfect equipment?
Gamma and Ultraviolet
Which animal has a fingerprint so similar to humans that it could ruin a crime scene?
Koala
Which EMS waves carry the sun's energy?
Ultraviolet, light, infrared
The number of coils around the nail of an electromagnet, and the number of paperclips that electromagnet picks up are listed below:
10 coils = 9 paperclips
20 coils = 18 paperclips
30 coils = 24 paperclips
Estimate how many paperclips an electromagnet with 40 coils would pick up.
Any number larger than 24
What property does a light wave have that makes it able to travel through empty space?
It travels like a particle, meaning nothing needs to carry it along.
The walls in our classroom appear blue to our eyes. Why?
The blue light wave reflects off of the wall, while all other colors are absorbed.
Which aquatic animal has the fastest punch, clocking in at about 50 mph?
Mantis shrimp
Which three types of EMS waves carry energy from the sun to the earth?
1. UV (ultraviolet)
2. Infrared
3. Visible Light
Voltage -- Paperclips attracted
4 1
5 2
6 3
7 4
Which current attracted twice the number of paperclips as a current of 5? What conclusion can be drawn about the voltage and strength of the magnet?
7 Ohms; The higher the voltage, the stronger the magnet.
Only 7% of the radiant energy from the sun reaches Earth as UV waves. Why can ultraviolet radiation still be a problem when such a small percentage reaches Earth?
The sun emits a lot of UV waves, so even 7% of that large number is still a significant number.
Give three uses of microwaves.
1. Heating up water molecules in food
2. Wi-Fi
3. Cell phones
This animal, commonly seen as a 'small' animal, can grow as large as an adult male polar bear.
Pig
