Games for 3 - 5yrs Preschool Science Fun - Blue flowers

Blue flowers / celery.

To help your children learn how plants / flowers need water and how it travels up the tem put aome blue food colouring in a jar with some water and put some celery sticks in. You will find that the blue colouring travels up the stalk so that if you cut it in the middle you can clearly see the blue colouring.

 

This also works really well with white flowers - if you put them in the blue colouring after a couple of days the petals on the flower goe slightly blue.

Once you get a bit more advanced you can split the stalk lengthways and put one in some blue food dye and one in some red food dye and see the different colous in the flower.
