Teachers Information
First attempt to document what kids in boats could do in marine science with low cost equipment
Many activities came from a workshop run by Drs Jack Marsh and David Tulip from the Mt Gravatt College of Advanced Education, who ran a teachers workshop at the Boyne Island Field Study Centre in 1980.
Here we were introduced to low cost field equipment and how plankton could be collected and identified. The workshop was funded from the GOSP schools commission grant and lit the spark from which many of todays marine science experiments came from.
We also tried out the hatch meters that were supposed to meaure salinity and dissolved oxygen.
The DO was a nightmare and it relied on osmosis and to get the correct seals, just did not work. Maybe some trainign would have been useful, but in those days all equipment arrived with a poorly written manual and it was really hard to figure things out.
I don't think you can make Chromic Acid today and many of the chemical techniques have been repalced with meters and probes.
BUT
The benefits of using chemicals are
- Every student gets a go at taking measurements
- Students learn the importance of wearing personal protection
- There is an element of danger
- There is a greater skill in being careful
- Disposal of waste can be taught
