Testing the Effects of Sugar on Concentration




Measure how sugar intake affects concentration and attention.


  • Concentration tests (e.g., puzzles, memory tasks)
  • Sugary snacks
  • Non-sugary snacks
  • Participants
  • Notebook for recording data


  1. Divide participants into two groups: one consuming sugary snacks and the other consuming non-sugary snacks.
  2. Have participants perform concentration tests before and after eating the snacks.
  3. Record the test results in your notebook.
  4. Compare the pre- and post-test scores for each group.
  5. Analyze your findings to determine the impact of sugar on concentration.
  6. Present your results in a report, discussing how sugar intake might influence mental focus.
