These are known as the building blocks of life
What are cells?

This simple machine can be described as a rigid bar that pivots about a fulcrum.
What is a lever?
100

We can calculate this property of a substance by dividing its mass by its volume.

What is density?

100

This is the term given to a mountain peak which has been carved out due to glacial movement

What is a horn?

100

When light bounces off another object, it is said to do this

What is reflect?

200
This organelle is known as the cell's "powerhouse", breaking down sugars and providing energy to the cell.
What is the mitochondria?
200

This simple machine provides mechanical advantage by providing a gradual slope for an object to be pushed up

What is an inclined plane

200

This property of fluids describes how "thick" or "thin" a fluid is.

What is viscosity?

200

This is a body of water which is shallow enough that sunlight can still reach the bottom throughout

What is a pond?

200

Why does a red apple appear red

Red is the only colour that is being reflected (all other colours are being absorbed)

300

What are the two types of lenses on a Compound microscope

What is an Objective lens, and an ocular lens (Will also accept eyepiece)

300

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

What is distance x force

300

This is a type of heterogeneous mixture where solid particles do not dissolve in a liquid solution 

What is a suspension?

300

Of all the water on the Earth, how much is freshwater that is currently in the oceans as ice

What is 3%

300
This form of light is produced from chemical reactions

What is chemiluminescence?

400
This organ system has the kidneys as its main organ, and allows the body to filter out toxins and release them from the body.
What is the excretory system?
400

In terms of Mechanical systems, what is energy?

What is the ability to do work

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

A build up of too much nitrates and phosphates in the water can lead to eutrophication and you may see these

What are algal blooms

400

These types of cells are found in the retina and are help us detect colour

What are cones

500

These are two structures found in plant cells, one is to help transport water, and the other is to help transport sugars.

What is Xylem and Phloem

500

Why can the efficiency of a machine never be equal to or more than 100%

Because energy is always lost through heat, light, or sound (Waste energy)

500
This scientific principle describes the fact that the buoyant force on an object is equal to the weight of the fluid it displaces.
What is Archimedes' Principle?
500

This is the term for small creatures in fresh and saltwater systems whose presence may help determine how healthy the ecosystem is

What are bioindicators

500

This is the most powerful type of electromagnetic radiation

What are gamma rays (or waves)
