20.1.21 Rock experiment
As you watch the video ask yourself the following questions: Does the rock allow water to pass through? (permeable) Is the rock hard wearing? (durable) Do you think it would sink or float? (high or low density) Is the rock hard or soft? Is the rock igneous, sedimentary or metamorphic? Do you notice anything else about the rocks? How does the rock change when water is poured on to it? After, you may wish to go on a walk and see what kind of rocks you can find.
