What are Atoms?

Atoms are the smallest practicals.

100

What is convection?

Convection is a type of air.

100

What is evaporation?

It is when water heats up and turns into steam.

100

What does the Engineering design process do?

It is a way to design a invention to solve a problem.

200

What are Atoms made of?

Atoms are made up of neutrons, protons, and electrons.

200

What does Convection do?

Convection is when cool air sinks into the ground and warm air comes out.

200

What is the Water Cycle?

The water cycle is when water evaporates and goes up into the clouds and then rains and does it constantly. 

200

How many phases are there?

There are four phases.

300

What do Atoms do?

They make up everything in the world.

300

Which warm or cool air is denser?

Warm air is denser.

300

What is the heart of the water cycle?

The sun is the heart of the water cycle.

300

What is the first phase of the engineering design process?

The first phase is to research.

400

Where are the Atoms parts?

The neutron is in the middle, the proton is surrounding the neutron, The nucleus contains protons and neutrons, and electrons circle around the other parts of the Atom.

400

Which direction does the warm air go?

Warm air goes up.

400

What is infiltration?

Infiltration is when water soaks into the dirt.

400

What number of the part is sensitivity analysis?

It is number 3.

500

What do the parts of Atoms do?

Electrons have a negative charge, neutrons have no electric charge, nucleus contains protons and neutrons, and protons have a positive charge.

500

Why does cool air sink?

It does because it is less dense.

500

Can the water cycle stop?

It can not unless the world stopped turning.

500

What are all of the parts of the engineering design process?

They are research, build, sensitivity analysis, and final build.
