My Observation Report

In week 4, We received a piece of paper saying what we should do to our experimental plants. It was to cover the leaves in vaseline and write down how your leaf looks. So we tested it out.

We then put two cups on the table and filled it with soil, then dumped the plant onto the first layer of soil followed by one more top layer of soil. Then we smeared vaseline onto the leaves and then we put bamboo sticks next to the plants to keep them straight. Then we put the plants on the experimental desk for the weekend.

On Monday we noticed nothing, they just went a bit brown, the next day one of the plants started to go dark brown. Following that, was that the plant started to die and the other plant was dark brown. After two weeks we noticed that one of the plants was dead and the other one was nearly dead. The next week both of the plants were dead, with the leaves burned/suffocated and were hanging off the cup’s side.

I discovered that plants with vaseline on one or more of the leaves blocks the plant from producing oxygen or breathing in carbon dioxide and they started to suffocate, being choked by the vaseline which did not enable them to grow and killed them. This is how our science experiments ended. I felt excited about doing this with my friends and I learnt what vaseline does to plants.
