Colour the flowers!

Our first lesson and I started with one which engaged both The Eldest and Imp. It was a really simple one to do to show the process of transpiration. When I asked them what they thought would happen, The Eldest was rather stumped while Imp came to the conclusion that "the water would make them pretty". I was very impressed that my four year old had deduced this.

Experiment: Changing the colour.


Place some humble tap water in three glasses:

Raid the pantry for some food dyes:

Place some colour in each glass and put your flowers in for a drink. Imp helped me pick some daisies from our garden:

Drink up Daisies!

And two hours later .....

In the meantime, The Eldest was writing up his hypothesis and procedure while he was waiting to collect, record and analyse the resulting data.

Final result! Imp thought it was very pretty!

Next Day.
