A student investigates the rate at which the temperature of water inside a beaker increases when the water is heated.
Plan an experiment to investigate how one variable affects the rate at which the temperature of the water increases.
The apparatus available includes:
- a selection of beakers
- an electrical water heater
- a supply of water.
In your plan:
- state the one variable you have chosen to investigate
- name any other apparatus needed
- give a brief description of the method, including what you will measure
- state the key variables to be kept constant
- draw a table, with column headings, to show how to display the readings (you are not required to enter any readings in the table)
- explain how to use the readings to reach a conclusion.
