Our Science topic this term is called Plants in Action.
Several weeks ago everyone placed two seeds in a plastic bag with a damp cloth. The plastic bags were then hung against the window so they could receive sunlight.
This task helped us see what the first stage of plant growth is which is called germination. We have learnt that in order for germination to occur a seed must have water, sunlight, oxygen and the right temperature. Every few days we have been recording our seeds growth.
We now know that the plant seed contains a dormant plant embryo. When the seed soaks up water, the seed coat loosens and the embryo is activated by the moisture. If there is enough warmth and air it will start to grow. Some students have been more successful than others with their seeds, however it has been really fascinating watching them grow daily.
By watching the seeds grow we can see that the first root which is called the radicle pushes out from the seed first. This is then followed by the first shoot which is called the plumule.
We watched this video in class which helped explain the stages of plant growth.
This term we are also learning about the reading strategy called ‘activating prior knowledge’. This involves us using the knowledge we already know about a subject when reading a text to help us make sense of what we a reading. It also helps us to connect what we already know and to build further knowledge for the future. We used our prior knowledge about plants to complete a ‘before and after web’ in partners. In our partners we had to write up to 4 facts that we already knew about plants. We were then given books and ipads to find some more facts to build upon our knowledge.
