Observing in science

On Wednesday afternoon Reception began a scientific experiment to find out what happens to white flowers if you put them in coloured water.

First we looked at the flowers and talked about our knowledge of flowers. We could name some parts of the flowers, like petals and leaves, and we knew that flowers need to be put in water.

We had white roses and white chrysanthemums and we put them in separate bottles. Then we added either blue, red or green food colouring. For each flower we left one bottle with clear water in.

We talked a lot about what we thought might happen. Some of us thought the flowers would grow, some of us thought the stem might change colour and some of us thought the petals would change colour. We also talked about how we will know what has happened - we are going to have to use our sense of sight to observe the flowers over time to see what happens!

We drew a picture of our experiment - we'll use this on Friday to compare to our results so we can clearly see what has happened to our flowers!






By the end of the afternoon, the edges of the petals of the flowers in the blue water had started to turn blue!

This morning we were very excited to see that the flowers in the blue, red and green water have all started to change colour!



We're going to keep watching our flowers - check back on Friday to see what they look like!
