Introduction to Year 12 Biology
Aims:
To improve your understanding of the topics studied in AS Biology;
To be able to describe the structure & function of water.
To set a ‘summer Biology assignment’
1
WATER, WATER EVERYWHERE.
Complete the spider diagram below to describe all the things you know about water,
structure, bonding and function (uses) in plants & animals.
Water:
2
Work in groups of two or three.
Use the resources provided to carry out the following tasks:

Use the molymods to make a water molecule. Draw this in 3D:

Turn on the tap slowly. Why do the water molecules stick together? This explanation can be linked to
the molecular structure of water.

Take two microscope slides, put a thin layer of water between them, and choose one in your group to
pull them apart. Explain your observation.

Put one of each size of the glass tubes into the coloured water. Write down the results for each one.
Explain your results.

Look at the ice on the water.
Why does the ice form on the surface first?
What is the significance of this to living things?
