Hello! We did our experiment last Friday! :D
We did changes to our experiment, below is the final one.

Aim: To test if the amount of light will affect the rate of photosynthesis (light intensity)
Materials / Apparatus: 1 Tracing paper. (translucent)
1 trashbag. (opaque)
3 beakers, 1 plant inside each beaker.


Steps : 1. Put 1 plant into 1 beaker each. Cover the first beaker with tracing paper.
2. Cover the second beaker with trashbag.
3. Leave the third beaker uncovered.
4. Shine light at the first & third beakers. Put the beaker covered by trashbag in a corner where there is no light.
5. Wait for 20-30 minutes and record the oxygen rate.
6. Study the graph. :)



Report 1 (TRACING PAPER)


The graph is prepared to record the changes in photosynthesis due to different light intensity. It was carried out using a beaker of water with a water plant inside it. The beaker was covered using a piece of tracing paper and light was shone at the beaker.

The experiment was carried out for around 20-30 minutes to see how much a plant can photosynthesize when it is covered with tracing paper.
A graph was recorded after the 20-30 minutes. The graph was recorded for 50seconds.

The graph that was recorded showed a quite smooth line but oxygen decreased from the start until around 20 seconds later. The oxygen then rose and fell again at the 30th second.
It continued decreasing slowly until the 50th second.

K bye! The other 2 reports will be up soon.
Be patient! :D
