Students will investigate the following question
‘How much soil is blown away when we use a straw to blow consistently on a landscape for 20 seconds?’
Students will take two containers and using a spoon fill each container to the top with soil from the garden. Then leave one container ‘dry’ and use a spray bottle to ‘dampen’ the soil in the second container so that it is moist. Students will weigh the dry soil and record the weight.
To conduct the investigation one student places the dry container at the end of an A3 piece of paper and sets the timer to 20 seconds.
The student places the tip of the straw at one end of the container and blows across the soil landscape for 20 seconds. They are modelling the effect of a strong wind.
The student weighs the container a second time (after blowing) and records the weight
Now repeat for the second (moist) container.
