Today we played a game to show how important plants are for humans. We learned that plants release oxygen when they are busy making food. Half the class had to represent trees and stand spaced out. The others could walk around and imagine that they had to hold their breath until they reached a tree. Some pupils had the jobs of cutting down the trees to make things. The more trees that disappeared, the harder it was to get oxygen.
We have worked in groups to plan a fair test to investigate basil plants. We all decided in our groups what our investigation question would be. We made sure we only changed one factor and kept all the rest the same. We observed our plants over a few weeks and used our results to reach conclusions about what plants need to be healthy.
A lot of water
Class 7 have been investigating the functions of different parts of a plant. We have set up an investigation, which will help us to understand the job of the stem. We added some food colouring to a little water and then added a celery stem into our cups. We also added a flower to the cup. We are going to observe what happens over the next couple of days. We have made some interesting predictions about what we think will happen. Quite a few of us think that the celery stem and the flower will change colour, some of us thought only the leaves will change colour. Some people suggested that the water will go green because the celery is green. We can't wait to see if our predictions are right!
Looking closely at our celery stems.
What do we predict will happen?
We wonder if our predictions will be correct?
