Absorbent Materials

This week, 3C have continued to explore the characteristics of materials. Yesterday, we learnt all about absorbency (the ability to soak up liquid). As always, our week began with a practical experiment. Miss Campbell decided to use this opportunity to find out which teacher buys the most absorbent kitchen towels. Miss Prest and Miss Bialek were very kind and each brought in a sample for us to test. Here are the results of what we found...

Miss Bialek uses 'Tesco Value' kitchen roll , we found this to be the least absorbent. Perhaps that is why is it the cheapest. 

Miss Prest uses 'Thirst Pockets', we found this to be the second most absorbent kitchen roll. 

Miss Campbell uses 'Plenty', our results showed that her kitchen roll was the most absorbent. It was, however, the most expensive one too!

Here we are, testing the different paper towels...

When we had finished testing the paper towels we had a chance to observe how quickly the water was absorbed. We did this by dipping the towels into a beaker of water and food colouring. Not only were we able to watch the magical absorption taking place but were also left with beautifully coloured paper towels with a difference! 

So next time mums and dads need help cleaning up a spillage, just call on us!
