VII .Experimentation

• The students in grade 6 conducted an
  investigation on the sugar content of their
  favorite food. In the experiment used 1 bottle of
  Benedict's solution, assorted small pieces of
  food such as cookies, crackers, bread, fruit,
  several glass test tubes, 1 alcohol lamp and
  tongs. They placed a piece of food in each test
  tube and then poured 30 - 40 ml of Benedict's
  solution over the food. They heated the test
  tubes one at a time over the burner, using the
  tongs to hold the test tubes. According to their
  research Benedict's solution is blue. The
  presence of sugar will turn the solution to orange
