Question 1
Part A
Investigation 1: Investigating different soil types – measuring how much water different
soils can hold (Grade 5 – term 4)
Step 1: Identify a problem and develop a question. What is it you want to find out?
- Problem/Question: How does the type of soil affect its water-holding capacity?
Step 2: Form a hypothesis. A hypothesis is your idea, answer, or prediction about what
will happen and why.
- Hypothesis: I hypothesize that different types of soil will have varying water-holding
capacities, with sandy soil holding less water compared to loamy soil.
Step 3: Design an activity or experiment. Do something that will help you test your idea
or prediction to see if you were right.
- Activity:
- Collect samples of different soil types, such as sandy soil and loamy soil.
- Set up containers of equal size and weight for each soil sample.
- Add a measured amount of water to each container, ensuring the same volume for
each.
- Place the soil samples in the containers and allow them to absorb the water for a
specific time.
- Drain any excess water from the containers and weigh them again to determine the
amount of water retained by each soil type.
Step 4: Observe/note changes/reactions (e.g., through measuring) and record your
observations (e.g., onto a table). What were the results of your activity or experiment?
Write about what happened.
- Observations/Results:
