The Plan

* Q. What am I trying to find out?

* A. How the volume of water affects the time that it takes to boil.

* Q. What do I think will happen?

* A. The larger the volume the longer the time to boil.

* Q. Why do I think it will happen using scientific ideas?

* A. The larger the volume, the more atoms you need to heat.

* Q. What will I measure?

* A. Time versus volume.

* Q. What will I alter between observations?

* A. The volume of water.

* Q. What will I do to ensure a fair test?

* A. Keep everything the same except the input variable: volume.

* Q. How will I decide on the values of the variables that I will be using?

* A. Values will be chosen to enable the experiment to be carried out in a reasonable time, and to give a good range for trend analysis.

* Q. How many measurements will I take and how will they be spaced out?

* A. 50ml to 200ml in intervals of 50ml, i.e. four different measurements.

* Q. What equipment will I need and how will I use it?

* A. Timer; Beaker; Tripod; Bunsen Burner; Gauze; Heat Proof Mat (HPM); Goggles:

* Q. How will I take any safety situations into account?

* A. Wear your goggles at all working times to protect your eyes from boiling water; HPM to prevent ignition and overheating of the desktop.

* Q. How will I ensure that my experiment is reliable?

* A. I will repeat the investigation at least once.

* Q. How will I record the results?

* A. I will record times in whole seconds.

Obtaining And Presenting Evidence

Whilst me and my partner carried out this experiment we:

* Worked safely,

* Made as precise observations as possible,

* Took ...
