Dying to Test Plants

After viewing flowers that had been transformed using food colouring, students designed and conducted their own experiments about different plant parts and their functions.

They came up with really creative (and messy!) experiments. We discovered that some parts of the plant are better suited to transporting liquids than others. Stems works well but roots seem to have a coating around them that blocked the dye. Flowers and leaves are hard to colour directly from the outside, they only changed colour when the dye came through the stem. Cauliflower was the fastest to change colours in case you were wondering :)

  1. Our class was really dying to test plants! My group were so amazed at the parts that looked so ordinary but they turned out to be lots of amazing parts of a plant that each had their own functions. This experiment was very fun and helpful! ツ
