1. Use a measuring cylinder to measure 100 cm3 of cold water and put it in a metal can (record the temp of the water)
2. Then place 1 gram of sugar onto a tin lid and place this lid under the bunsen flame
3. Once the sugar starts to burn, move the tin lid under the metal can containing the water, so that the flames from the sugar touch the bottom of the tin can, and so warm the water
NOTE: If the sugar stops burning, move the tin lid back to the bunsen burner to set it alight again. Then move the tin lid back to the water
4. If the sugar has stopped burning and can no longer be ignited, record the new temperature of the water.
To work out the rise in temperature from the water, take away the 1st temperature from the 2nd (2nd temp - 1st temp = rise in temp of the water).
They get the food and light it on fire and put it under a test tube of water. How much energy is in the food depends on how much the water has heated up
food web, just took the test ;)
