The Biology of Water Quality

Without water there is no life.  This makes water an extremely valuable resource.  Having the skills to monitor water quality is therefore becoming increasingly important particularly for industries such as aquaculture.  You could collect water samples from your local streams or rivers to see what is living in them.  Contact your local council to see if they would give you any help on which streams may be safe to access.

Dissections

How to dissect a green-lipped mussel

1. Buy your mussels!  You can easily buy these from the supermarket.  In fact you could buy enough for the entire class so they've got one each!

2. Put the mussels in the freezer overnight so that the shells open.

3. Use a pair of lab scissors to cut the adductor mussel which is about 1cm from the top of the fat end of the mussel shell. 

4. Carefully open the mussel without cutting yourself on the shell.

5. Draw the mussel.

6. See what you can identify using information from your teacher or from books.

 

 

Polychaete Dissection

 A polychaete is a marine worm.  You can easily find some at low tide hiding in or under the rocks.  You have to look really carefully as some species are very small.
