When you water the soil of your plants, how does the water travel from the soil into the plant and out to the leaves? Tiny tubes (xylem) draw the water up from the roots like a straw. It works by a capillary action. The water molecules suck up inside the tiny tubes and move up and out to the leaves as if someone was sucking on the end of the tubes. The suction actually occurs as a result of water in the leaves evaporating very slowly.

Topic-Biology

Title- Colourful Celery!

Hypothesis- The coloured water will travel up the veins (xylem) of the celery with the leaves and not the celery that is left as a single stalk?

Equipment-Clear cups, Cold water, food colouring and celery, (with leaves and stalks)

Procedure– This morning a broke off two stalks of celery. Left the leaves on one and broke them off the other and placed both sticks of celery into water coloured with food colouring.

I took photos of the celery throughout the day to see to monitor what as happening to our celery.

This afternoon during science we witnessed …….because…….

What will happen to both pieces of celery if we leave them in the coloured water over night? Why?
