An iron screw rusting due to oxidation is a good example of this.
What is a chemical reaction?
This property allows an object to float on top of water.
What is a density less than water?
This formula is used for calculating speed.
What is Speed = Distance / Time?
This results when there is movement in a particular direction despite the forces being in opposite directions.

What is time?
Water flowing over a waterfall is an example of what kind of energy transfer.
What is Potential to Kinetic Energy?
On a position-time graph, this represents an object that is not moving.
What is a horizontal line?
This is a necessity for a scientific hypothesis.
What is a testable statement?
When adding a red liquid to a clear liquid, the temperature remains the same, the solution turns pink, and solid particles are seen forming at the bottom of the solution. This is the evidence of a chemical change. What is this evidence called?
What is solid particles formed?
Colorless, odorless gases are found here on the period table of elements.
What is the right/upper-right side of the P.T.O.E.?
An example of this type of heat transfer is feeling a door for heat during a house fire.
What is conduction?
This is what a student must do in order to test the force needed to propel a toy car with a balloon the same distance in repeated trials.
