=**Variables**=
 * A Variable is a factor in an experiment that we are able to change.**
 * Eg in heating water we could change -**
 * **time we heat it,**
 * **how much water we use**
 * **the strength of the heat**
 * **what you heat water in**
 * **how far the water is from the heat.**
 * In the expt how long does it take to heat water**
 * Dependent** (or the measured) **variable is the time in seconds the water took to reach 100 degrees Celsius**


 * Independent variable** manipulated variable **is the strength of the heat used. In this case the Bunsen burner on a heating flame - but if we had used a candle we might expect it to take longer. We control all these other variables like how much water we are heating, the distance to the flame etc**


 * The dependent variable is the one we are measuring.**


 * Fair tests**
 * we control all the variables except the one we are testing. So in the bouncing ball experiment we want to know which type of ball bounces highest.**
 * We will control the height from which they are dropped the**
 * The surface on to which they are dropped**
 * how new the ball is**
 * how you drop the ball.**
 * the way you measure how high it bounces?**

Aim: To determine which ball bounces highest. Hypothesis: Method:
 * Bouncing Ball experiment**
 * 1) Equipment required is metre rule, 3 different balls, table top.
 * 2) Drop the first ball from 1 metre and measure how high the bottom of the ball bounces up.
 * 3) repeat this 3 times
 * 4) Record results in a table
 * 5) repeat steps 2, 3 and 4 with another ball and with all other balls.

Results: first trial ||  ||   ||   ||   ||   ||   || Discussion
 * Ball type ||  || Tennis ball ||   ||   || Rubber ball . || Ping pong ball . ||
 * Height it bounced
 * trial 2 ||  ||   ||   ||   ||   ||   ||
 * trial 3 ||  ||   ||   ||   ||   ||   ||
 * average ||  ||   ||   ||   ||   ||   ||
