Experiment: Changing colour of flowers

Dear 5th grade students,
This week we are going to do the following experiment:
Where does the water go when a plant is watered?
You can have a look before we start...

This time we'll need white flowers, food colouring, water and some glasses or plastic bottles

Experiment: Extract chlorophyll from plants.

In this experiment we extract chlorophyll from lemon tree leaves.
We need green leaves, some alcohol, some sugar, a mortar, filter paper, a funnel and a glass.

Beans like the water in Sant Jordi. Peas don't like it.

We look how our seeds grow...
We observe that beans grow, but peas don't grow.
We take out the grass and leaves, and we put it in the compost bin.

Experiment: Onion cells under the microscope

In this experiment we see onion cells under the microscope.
We cut a little onion peel. We put some iodine on it. We use tweezers, we put it on the slide and we cover it.
Now we can look at the onion cells under the microscope.
