AMAZING SCIENCE NO 4 – BIOLIGICAL SCIENCE – TRANSPIRATION

OUR LAST INVESTIGATION WAS LOOKING AT HOW PLANTS TRANSPIRE  WATER.

As you can see it is a fairly simple procedure. We place a plastic bag over a potted plant {chrysanthemum} and secured it with tape around the base of the pot .

We left the plant overnight and next morning eagerly  removed the plastic for inspection.

Predictions

  • the plant will with die
  • it will be very droopy
  • it will need of some water

What we found

Zac – It’s wet {on the inside of the plastic}

 

Transpiration investigation.  You will need – a clear plastic bag and an elastic band.                                                                                   This experiment will show you how much water is transpired through the leaves of plants.                                                                         Try this with a few different plants to see if the results are different.                                                                                                                  Many plants take water in through their roots and pass it out through their leaves through tiny holes called stomata                                                                                                                                                                                                                      Step 1 Tie a clear, clean plastic bag firmly around some leaves on a bush, taking care not to harm it. Make sure the bag has no holes in it.                                                                                                                                                                                                                       Step 2Check the bag daily to see what happens. Are all bushes the same?

  1. I think its amazing how the plant takes the water through the roots and it spits it out through the leaves as it grows.
