This organelle is known as the cell's "powerhouse", providing energy to the cell.

What is the mitochondria?

200

Double points: This simple machine is the main one found in the blade of an axe.

What is a wedge?

200
We can calculate this property of a substance by dividing its mass by its volume.
What is density?
200

Double points: This is a popular chemical used to disinfect water to kill bacteria and other harmful microorganisms.

What is chlorine?

300

Double points: This is the process whereby plants turn sunlight, along with carbon dioxide and water, into food (sugar) for the cell and oxygen

What is photosynthesis?

300

This class of lever finds the effort located in between the fulcrum and load.

Where is the effort, load, and fulcrum located in a third class lever?

It is the choppy airflow that causes people to feel queasy on an airplane ride.
What is turbulence?
300

The sun shinning on ice and turning the solid water particles into water vapour

What is sublimation?

The equation to calculate work done on an object involves multiplying these two things.

What is force and distance?

400
This branch of engineering makes use of compressed gas or pressurized air to provide fluid power to various systems, including air brakes.
What is pneumatics?
400

Double points: Desalinating water by changing its state from liquid to gas, and then back to liquid (evaporation and condensation).

What is distillation?
