We had fun seeing which material would make a good strong seat for Ronnie. Some materials were ok , but not so good when Ronnie had his heavy shopping with him!

We discovered that some materials have tiny holes in them when seen through the magnifying glass. These materials weren’t very strong.

We tried to watch the dvd clip where Dr Brain also tries a similar experiment but it wouldn’t work in class; so if you’d like to enjoy it at home, just click on the link.http://www.bbc.co.uk/education/clips/zxj9tyc
