Set up the soils as you see in the picture below; in funnel A, the soil will hold some of the water you pour in. In funnel B, the other soil will also hold some of the water you pour in. But will they hold the same amounts? Setup the soils in two funnels like this. What will you do to make sure you are being fair? Teacher's Note The learners should realise that the amount of water and the amount of soil in each case should be the same to make it afair test. AIM (What you want to find out): PREDICTION/HYPOTHESIS (What you think will happen): MATERIALS AND APPARATUS (what you will need): Look at the pictures above to help you write a list in the space below. METHOD (What you must do): Write out the instructions for how to carry out this investigation below. Remember to number the steps. 118 Earth and Beyond
RESULTS AND OBSERVATIONS: What did you observe when doing this experiment? Use the space below to draw a bar graph to show your results from this experiment. Remember to label the axes of your graph and give it aheading. Teacher's Note A bar graph is used as we are comparing two dierent things (soil A and B) and they are not related to each other. The "Soil type" will go on the x-axis and the "Amount of water held by soil" will go on the y-axis, probably measured in millilitres. How you could do this investigation better? CONCLUSION (What you learnt): Write a sentence where you give a conclusion about what you learnt from this investigation. See if you can identify what types of Soil Aand Bwere. For example, I learned that the soil from the bottom of the hill holds more water than the soil from the top of the hill. Also ask learners to identify what type of soil they think Soil Aand B. Sandy soil does not hold much water. Clay soil holds too much water. Clay holds water because it has very small grains. The grains fit together tightly. Loam soil has a mixture of sand and clay, along with composted plant and animal substances. So, loam soil holds water well, but does not become waterlogged like clay soil. QUESTIONS Why does sand let the water run through quickly? You are asking the children to make a hypothesis based on the information about the size of the grains. Sand grains are much larger than clay grains, and so they don't fit together so tightly and so there is more space for the water to run through. Chapter 2. Surface of the Earth 119
