Experiment: Measuring abiotic features of the ecosystem

1. Y E A R 8 – E C O S Y S T E M S
MEASURING ABIOTIC FEATURES
OF AN ECOSYSTEM

2. AIM & HYPOTHESIS
• AIM: To measure the
different abiotic features
of an ecosystem.
• HYPOTHESIS: Write
your hypothesis here.

3. EQUIPMENT
• Pond water
• Tap water
• Test tube
• Measuring cylinder
• Universal indicator
• pH chart
• Thermometer
• Stopwatch

4. RISK ASSESSMENT
Risk Injury Prevention
Write down all the risks in your experiment.

5. METHOD
Part 1: Acidity of tap water and
pond water
1. Add about 3 mL of tap
water in a test tube. Add
about 3mL of pond water in
another test tube.
2. Add 2 drops of universal
indicator in your test tubes.
3. Using a pH chart, work out
the pH of your samples. The
smaller the number the more
acidic it is.

6. METHOD
Part 2: Measuring air
temperature
1. Using a thermometer
measure the temperature
of air at ground level.
2. Wait 2 minutes before
recording your results.
3. Repeat the measurement
but this time at bench
height. Wait 2 minutes
before recording your
results.

7. METHOD
Part 3: Measuring soil
temperature
1. Using a thermometer
measure the temperature of
soil at near the stage. You
can do this by inserting the
tip very gently into the
ground.
2. Wait 2 minutes before
recording your results.
3. Repeat the measurement but
this time in the oval. Wait 2
minutes before recording
your results.
