In this lesson, we will be learning about absorbency. We will test and compare the absorbency of a variety of household materials. You will need a piece of paper and a pencil to complete today's lesson. For the experiment, if you would like to take part, you will need: a sponge or cloth, plastic bag or cup, foil, cardboard or paper, cotton wool or tissue. If you do not have these materials, you can watch me complete the experiment while observing the outcomes.
