Slowly pour the water onto the soil,<br />
<strong>and</strong> wait 5 minutes.<br />
Has all the water run through the<br />
soil?<br />
Let's do an investigation to see how much water the dierent soil<br />
types can hold. For this investigation activity you need two<br />
dierent kinds of soil, from two dierent places. Let us call them<br />
Soil A<strong>and</strong> Soil B.<br />
Teacher's Note<br />
Try <strong>and</strong> get soils of dierent soil types –ie. s<strong>and</strong>, clay <strong>and</strong> loam<br />
soil. For the following investigation, the learners will have to plan<br />
some of it themselves <strong>and</strong> will not be told step-by step what to do.<br />
If you want to, you can make the investigation include all three<br />
dierent soil types if you manage to get samples from each, <strong>and</strong><br />
then you will have Soil A, B<strong>and</strong> C.<br />
Plan an investigation to compare Soil A, Soil B<strong>and</strong> Soil C, <strong>and</strong> then<br />
do the investigation. The main question you must answer is the<br />
question, which soil holds more water?<br />
INVESTIGATION: Which soil holds more water, Soil Aor<br />
Soil B?<br />
When you compare things, you must be fair. For example, if we<br />
want to compare runners in <strong>Grade</strong> 5athletics, we must let them run<br />
on the same track. It is not fair if we let some of them run through<br />
bushes but the others can run on asmooth track! We must treat all<br />
the runners in the same way, to be fair when we compare them.<br />
