ONE USEFUL TIP TO PRODUCE & COUNT BUBBLES from HYDRILLA PHOTOSYNTHESIS experiment

HERE IS A USEFUL TIP to help Hydrilla sp. or other aquatic plants produce noticeable oxygen bubbles that can be counted as the Responding Variable. HOWEVER, ONLY USE THIS TECHNIQUE IF THE Responding Variable in the Test Paper IS TO COUNT AND RECORD THE NUMBER OF AIR BUBBLES RELEASED IN A CERTAIN TIME PERIOD. JUST a gentle warning: Use this technique only if it's suitable and revelant, if it does not clash with procedures in the TEST PAPER. DO NOT SIMPLY USE THIS TECHNIQUE if it is NOT what the test requires you to do, or if it affects your results negatively. So please use your better judgement, ya.. cos teacher doesn''t know the question haha. Hopefully, the test paper also suggests this same technique😊 DO CHECK OUT THIS EXCELLENT PRACTICAL VIDEO WHICH IS SIMILAR TO WHAT WE ARE DISCUSSING HERE. Here is the link :    • Rates Of Photosynthesis - GCSE Scienc...   by Malmesbury Education. At 1:30 IN THAT VIDEO, the teacher shows the technique of cutting the stem in the solution. Use this technique only if suitable & if it does NOT clash with the procedure in the test Another video also shows the same technique .. at    • Photosynthesis with bubbling pondweed...   By Science and Plants for Schools. THE TECHNIQUE OF CUTTING THE STEM IS AT 5:40 min IN THIS SECOND VIDEO. For this second video, just view the section 5:40 to 8:00 minutes to save time.
