The energy of a moving object is called...
Kinetic Energy
100
This rapid back-and-forth motion is the primary source of all sound waves.
Vibration
100
These are the two ends of a magnet where the magnetic force is the strongest; opposite ones attract, while like ones repel.
Magnetic Poles (North and South)
100
A change in genetic material.
A Mutation
100
Which color in the spectrum bends the most?
What is violet (or purple)?
200
What two factors could be changed to impact the amount of force in a collision?
Mass and Speed
200
Sound waves travel fastest through this state of matter because the molecules are packed most tightly together.
A Solid
200
If a compass needle is a small magnet, what causes the needle to point North?
It is drawn Earth's magnetic field (towards the North Pole)
200
If a homozygous (ee) parent mates with a homozygous (EE) parents, what are the possible offspring?
100% heterozygous (Ee)
200
In June, how is the Northern Hemisphere tilted?
Towards the sun
300
According to Newton's 3rd Law, if a massive truck hits a small parked car, the force the car exerts on the truck is ________ to the force the truck exerts on the car.
Equal and Opposite
300
Increasing this specific wave property will make a sound louder without changing its pitch.
Amplitude
300
This invisible area around a magnet exerts a force on other magnets or certain metals.
The Magnetic Field
300
Where does an individual get its genetic material?
50% from each parents
300
In January, what kind of light is hitting Australia (Southern Hemisphere)?
Direct Light
400
This term describes the point where a material is stretched or compressed so far that it can no longer return to its original shape.
Elastic Limit
400
This property of a sound wave, measured in Hertz (Hz), determines the pitch of the sound; the faster the vibration, the higher this is.
Frequency
400
This continuous loop or path allows electricity to flow from a power source to a device and back again.
A Circuit.
400
What determines which organisms with different variations survive to reproduce?
Environmental Pressures
400
Descirbe the length of day in the arctic circle in this image.
24 hours
500
Features like airbags and crumple zones protect passengers by increasing the time of an impact, which results in a decrease of this.
Force
500
What is necessary to carry a sound wave from the sound source to the sound receiver?
A medium
500
In a speaker, this type of magnet is created when an electrical signal flows through a coil of wire, causing it to rapidly push and pull against a permanent magnet to create sound waves.
An electromagnet
500
Which set of fossils would be the oldest? How do you know?
The fossils in the brown section - they are the deepest/under the newer layers above.
500
What interactions (absorbing/reflecting) are happening with each color in the light spectrum so we can see the apple as red?
Red is reflected
All other colors are absorbed
