100

This type of wave allows us to see the world around us. 

Light

100

This type of energy is transferred from a warmer to a cooler object.

Heat

100

This describes the day to day conditions of the atmosphere.

Weather

100

A natural event that can cause damage to people, property, or the environment is called: 

Natural Hazard 
100

This is the basic unit of life.

Cell

200

This occurs when light bounces off a surface such as a mirror. 

Reflection 

200

In this state of matter, particles move the fastest.

Gas

200

This process changes liquid water into water vapor.

Evaporation

200

This weather hazard is measured using the EF scale.

Tornado

200

This scientist first observed and named cells.

Robert Hooke

300

A material that allows most light to pass through clearly is called: 

Transparent

300

This type of heat transfer occurs when heat moves through direct contact. 

Conduction

300

This process forms clouds when water vapor cools. 

Condensation

300

Scientists use this tool to detect and measure earthquakes

Seismograph 

300

An organism made of only one cell is described by this term.

Unicellular
400

This happens when light bends as it passes from one material to another. 

Refraction

400

This type of heat transfer occurs when warm fluids rise and cool fluids sink. 

Convection

400

The instrument used to measure air pressure. 

Barometer 

400

People cannot stop natural hazards but they can do this to reduce their effects. 

Prepare or mitigate 

400

This organelle is known as the control center of the cell.

Nucleus

500

A student shines a flashlight through a clear window. Most of the light passes through the glass. This property of the glass is called this. 

Transmission

500

This type of heat transfer allows energy from the Sun to reach Earth. 

Radiation

500

These two forces drive the movement of water through Earth's water cycle.

Sun's energy and gravity 

500

Knowing a hazard may happen in the future is called:

Prediction

500

Cell, tissue, organ, organ system, and organism are examples of this biological hierarchy.
