Introduction

This is probably one of the most interesting things to for the kids out there. This is one of the best ways to see the water flowing through the stem of the flowers.


           


This is a classic and fun thing to do with friends and folks and experimenting this is even more fun than the usual. It is sure to give you a “WOW" reaction every time you see it or do it. The experiment explains how water travels all the way through the stem with the help of the xylem to get to the levels of the xylem.

Apparatus

  1. Stems of white flowers that are bright like gerberas or daisies.
  2. A jar that is filled up with water and different colours/shades of food colouring.

Procedure

Step 1

Take a different jar and colour each jar with a different colour of food colouring. Simply put the flowers in the respective jar.

Step 2

Give the flowers some time to settle in. Almost in an hour or so, you can see the petals of the flowers changing their colour. The blue and green dyes are considered to be the strongest and the flowers dipped in them are the ones that will convert in the beginning.

Step 3

For having a good learning experience, you can sit down to analyse the whole thing and to have a better understanding of how the colours actually reached out to the petals. It would be really fun to discover it out and more so, the knowledge you gain from the understanding would be something you can cherish always.

Step 4

In a day or two, you can see the petals changing their colours. The food colours reach the petals completely and the look of these flowers are really beautiful and pretty. Also, one thing to notice is the fact that the purple food colouring will turn the petals of the flowers to blue and not purple. From this, you can have an understanding of the combined dyes and splitting of colours.

Result

Well, the kids conducted these experiments and they were really curious to find out on how the experiment actually happened.

So, before the experiment started, the kids drew this on their paper.

After waiting for as long as the experiments were on, the deduction was quite clear. The students saw the conclusion and this is what they came up with.

Conclusion

However, things were different with older children as they had other predictions and experimental results. They could validly name the part of the plants and also wrote the way the water moves through the xylem to the stems and finally to the petals.
