Biology Lab Tips for Photosynthesis

  1. Use grasses or other outdoor plants for chromatography.
  2. Set up numbered bank of tubes (0-10) using serial dilutions of DPIP if Spec 20 is not available. Students then match their tubes to color standards in tube bank.
  3. Place spinach in light prior to experiment to activate photosystems.
  4. Mix DPIP immediately prior to lab.
  5. Borrow Spec 20’s from other school or local college.

Borrowing equipment for classroom biology science fair projects is a great way to save money.
