Science: All About Plants

This term in Year 3 we have been learning all about plants.  This week, we learnt how plants transport water from their roots to their leaves via transpiration.  

We wanted to prove that plants move water all the way up to their leaves, using special tubes called xylem, so we designed an experiment to check.

First, we mixed some food colouring with plain water in a beaker.  Then, we added a lettuce leaf, making sure that the bottom of the leaf was under the coloured water.  We talked about making the test fair, and decided to keep one leaf in plain water as a control.

We are hoping that the leaves will change colour as the food dye is transported through the plant, and we are excitedly awaiting the results!
