Fieldwork activity 1:

Physical and chemical

water testing

Test 1: Water temperature

Use the Youtube clips below to see how and why we do physical and chemical testing of the water at Blacktown Showground. At the very end or below each clip you will see the results. Record these in your workbook on Page 5.

Test 2: Dissolved Oxygen

Look at the photos below to see what you think the result is. You can work this out by seeing which colour on the indicator tubes matches the colour in our test tube. Record the number under the tube that it most closely matches in your workbook.

Test 3: Salinity (salt levels)

Make sure you watch the clip until the very end to see the result!

Test 4: Heavy Metals

Look at the photos below to see the result. Were there heavy metals in the water?
