|
Objectives |
| Children should learn: |
- how to use a Bunsen burner and heating apparatus safely
- how to use and read a Celsius-scale thermometer with care
- to decide which factors need to be controlled to make a fair comparison
|
Activities |
|
Outcomes |
|
Children: |
- Demonstrate and then instruct pupils in the safe use of the Bunsen burner and associated heating equipment. Tell pupils they are going to explore the output from natural gas fuel with the Bunsen burner set at different flames by measuring the temperature rise of a fixed volume of water in a beaker. Ask pupils to decide which factors they should keep the same in order to make a fair comparison.
|
|
- use a Bunsen burner safely and recognise the need for eye protection and other safety precautions
- use a thermometer accurately
- make a fair comparison of the output of different flames
|
|
Points to note |
- Pupils could be issued with a 'licence' to use a Bunsen burner, which could be revoked for rule infringements.
- The concept of temperature is developed in unit 8I 'Heating and cooling'.
