What is fusion?

Two atoms coming together

100

What is a gas

a substance that has no fixed size or shape.

100

What is newton’s first law.

An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

100

Which element has 34 protons.

What is Selenium

100

What is the crest.

The top of the wave.

200

What is fission?

An atom separating to form two different atoms.

200

What is a liquid 

a substance where the particles are still close together, but not as tightly bonded or in a fixed structure like a solid.

200

What is newton’s second law.

acceleration (gaining speed) happens when a force acts on a mass (object).

200

 Which element has 3 protons 

What is Lithium

200

What can be a medium

A solid, liquid, or gas

300

What is radioactive decay?

The particles and energy that are released are a form of radiation.

300

What is a solid?

firm and stable in shape

300

What is newton’s third law.

forces always act in equal but opposite pairs.

300

What element has 10 electron.

What is neon

300

What is a longitudinal wave.

A wave where the oscillation is in the same direction (parallel) as the motion.



400

How do nuclear power-plants work?

What is fission

400

Does all matter have mass.

What is true

400

What is the sun

500

A solid turning into a gas is called?

what is sublimation

500

An ice skater at rest pushes against a sled at rest, causing both the skater and sled to move away from each other with different accelerations. This is an example best described by

What is group 15.

500

What is refraction 

The change in direction of a wave as it passes from one medium to another.
