Science -Parts of a plant

During science this week, we used this game to help us learn what each part of the flower is for.

Who can name some of the parts and their function?

Water Transportation Experiment

Here is a similar version of the experiment we did in class today. Maybe you would like to carry your own experiment at home and let us know how it turned out. I wonder if a different colour of food colouring would have an effect. What about the size of the stalk?

Let me know your results.

  1. Celery Experiment

    Step 1

    Gather your materials.

  2. Celery Experiment

    Step 2

    Cut about one inch off the bottom of four celery stalks.

  3. Celery ExperimentStep 3

    Fill each jar about halfway with water. Then, drip a few drops of food colouring into each glass.

  4. Celery Experiment

    Step 4

    Stick the celery stalks in the coloured water and let them sit for about 20 minutes.

  5. Celery Experiment

    Tip!

    Rip open 1 or 2 of the celery stalks to better see how the color travels through the stalks.

  6. Celery ExperimentStep 5

    Come back to the celery after 20 minutes and check out the stalks! What do you see? Colour should start to appear in little dots on the ends of them!

This week we have learnt about the skeletal system in Science. We learnt the skeletons main jobs and some of the names of the bones. Can you remember the 3 main jobs of  the skeleton and can you remember any of the names of the bones?
