Science

Task 1 - Where does the water go?

To take part in this task you'll need either some celery or a carnation and some food colouring. If this is tricky to get hold of you could skip this activity and move onto task 2. 

Start by watching the carnation science experiment:

Colour changing carnations

This video shows how water travels up the stems of the flowers. Although not all coloured carnations are this colour because of the water they take up, some are this colour naturally. 

 

Today I want you to investigate this question to see whether it is true or false:

Water goes up the left of the stem to the left-hand side of the plant and up the right of the stem to the right-hand side of the plant.

 

Follow the instructions on the sheet below. 

Task 2 - What does the stem do?

 

If you did task 1, have a look at the celery and the carnation. You were investigating if it's true that water goes up the left of the stem to the left-hand side of the plant and up the right of the stem to the right-hand side of the plant. What has happened to your experiment so far? Were your predictions correct? If you have an adult handy, ask them to carefully cut the celery above the split. What can you see? 

 

Now watch the video and then look at the power point.

Task 3: Where do you new plants come from? 

First look through the power point. Then watch the film in the link and then complete the two tasks.

Task 4 - What do flowers have in common?

In this task you will be dissecting three different flowers. This means you need a flower that you can pull apart. If this isn't possible you can skip this. If you can take part this in activity you need to find three different flowers you can study (I bought a bunch of flowers from Aldi and picked out a rose, a lily and a daisy).

 

First look at the power point, then watch film clip 1. After that, watch film clip 2.
