Understanding Experiments

This week, we learnt about experimenting to identify how absorbent different materials are.

First we talked consistency, percision, careful measurement, repitition, and comparisons. Then we started to make an experiment with a measuring cup, water, food colouring, 50g material and tray.

Then we started to put water in 100ml in a measuring cup. Next we put 5 drops of food colouring. Then we had materials and we measured it on a scale to see if it was 50g. After I put the materiel in the tray and tip the water in it. Last we had to go on the recording sheet and see if the materiel absorbed all the water or not.
