Planning

        We are investigating heat loss from a container and how it is affected.

We could change:

        Room temperature

        Surface area

Amount of water

        Use a lid

        Insulate around it

        Colour of tin

We could measure / observe:

        Amount of time

        Temperature

We will change:

        Surface area

We will measure / observe:

        Temperature (every minute for 5 minutes)

Our question is:

        Does surface area effect the rate of heat loss?

We will keep these the same:

        Colour of tin

        Room temperature

Amount of water

        Use a lid

        Insulate around it

Preliminary investigation

Plan

  1. Collect 4 different sized beakers
  2. Boil some water in the kettle
  3. Pour 50ml into each beaker
  4. After 1 minute check temperature
  5. Repeat step 4 after another minute continue this for 5 minutes

Main Investigation

Aim

        To find out weather a beaker with a larger surface area cools quicker than one with a smaller surface area.

Fair test

        To make it a fair test we will keep the following the same:

                Colour of tin – we will use clear beakers

                Amount of water ...
