Top pan balance   
What level are you working at if you can explain why certain pieces of equipment are needed?

6. Self mark    Where am I…..
Equipment
Why is it needed
Different foods
 This is what will provide the heat energy
Bunsen burner
 This is to light the food
Forceps
 This is to carefully hold the food under the boiling tube of water
Clamp and stand
 This will hold the boiling tube
Boiling tube
 This will hold 50ml of water
Water
 This will absorb the heat energy from the burning food
Thermometer
 To measure the temperature of the water when it is heated by the food
50ml measuring cylinder
 This is to precisely measure out the amount of water
Top pan balance
 This is to measure the mass of food being used.   
What level are you working at if you can explain why certain pieces of equipment are needed?

7. Finding energy in food What you will be doing
When food burns, it releases chemical energy
If the food is burned under a test tube containing water, chemical energy in the water is transferred to heat energy and the water heats up
The hotter the water gets, the more energy there is in the food
