For starch, we carry out the iodine test.
For this test, it's just adding a few drops of iodine solution to the solid on a white tile. If it turns blue-black, starch is present.
For sugar, if you mean reducing sugar, we carry out the Benedict's test.
Firstly, add 2cm^3 of Benedict's solution to 2cm^3 of glucose solution in a test tube and shake the mixture. Leave the test tube in a beaker of boiling water for 5 mins.
As for the control experiment, repeat step 1 using 2cm^3 of distilled water in place of glucose solution.
