Investigating How the Volume of Water Affects the Time It Takes to Boil

Investigating How the Volume of Water Affects the Time It Takes to Boil

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.
