What is Potential Energy?
A variable that may be affected by the change of the independent variable.
What is the dependent variable?
52 + 43 =

Give an example that Mr. Yusuf used to explain convection:
air coming over the ocean at night toward the beach; the heating source of a kettle being at the bottom of the kettle; the air conditioner being at the top of the room; a heater being near the floor.

What is conduction?
The variable that is changed or manipulated by the scientist.
If you have a remainder from a division problem, does it go on top of the quotient? the dividend? or the divisor? Explain why this is so.
It goes on top of the divisor to create a fraction because that is how many parts are leftover from trying to make equal groups from the divisor.
For example: dividing 50 by 8, the quotient would be 6 groups of 8 with 2 leftover; that 2 goes over the 8 and needs to be simplified to 1/4. (because 2/8 = 1/4)
The result of a chemical change when there is a new substance that is formed.
What is a precipitate?
