1. To start of with, make a chart to record all your data in
2. For each food sample, you will need to take two readings, one before adding the invertase and one after
3. Label 7 cups with the name of your drink you want to put in it (e.g. Coke)
4. Take 15 ml of each drink and put it in the right cup. (Make sure all the drinks are at room temperature)
5. Use a glucose urine test strip to measure the glucose concentration level in each of the 7 food sample before you add the invertase
6. To do this, dip a test strip into each of the sample cups, one at a time
7. Watch the test strip for 5 seconds before you take it out
8. Once you take it out wait for 30 seconds before recording the colour
9. Record your results based on the colour of the test
