What is friction?
Lisa uses a metal, disposable straw. Her straw gets hot in her coffee because of this.
What is heat conduction from the coffee to the metal straw?
The system that transports blood and gases throughout the body.

This front causes severe storms because warmer air is forced up by a mass of fast moving cold air.
What is a cold front?
The reason the soil is not very good in a rain forest.

What is the respiratory system?
Part of the water cycle that causes cooling and clouds.
What is condensation.
The type of organism responsible for returning nutrients to the soil.
What are decomposers?
The way speed is calculated.
What is speed = distance / time?
The Earth gets energy from the sun through this type of heat transfer.
What is radiation?
The type of trait that caused Mia to have blue eyes?
What is an inherited trait?

One object has a mass of 10 kg. Another has a mass of 20 kg. They are traveling at the same speed for the same distance. This is possible when...
The 20kg object is pushed with a greater force.
A penny rusting, or a log burning in the fireplace are examples of this type of change.
What is a chemical change?
How Daniel is able to play the piano well.
What is a learned behavior, or an acquired trait.
The front that causes long periods of light rain because warmer air piles on top of cooler, denser air.
What is a warm front?
The reason it rains more at the equator than at the poles?
What is the sun's energy is more direct at the equator causing evaporation, which leads to precipitation.
