For this experiment, we want to determine which colour of light can help plant to grow the best. We use paper filters to built a cone with the top closed, this can make the plant only shine with one same colour, this can make our test more specific. As the result, we can see what the plant light with purple light grow highest at the first week, however, after the first week plants light with red, blue and green light all catch up with a very fast speed. If we can do our experiment one more time, we can improve it by, using more colour of paper filters to cover…
