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?


Bouncing Ball experiment
Aim: To determine which ball bounces highest.
Hypothesis:
Method:
  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:
Ball type

Tennis ball


Rubber ball .
Ping pong ball .
