Hi All,
one of the mandatory pracs for HSC Senior Science requires testing of silicon. Our teacher requested silicon tubing which is quite expensive & out of our budget. What do other schoole do for this prac?
Thanks.

Hi Hel
We use a silicon putty that comes in a tube and is used as a sealant (eg silastic). I extrude lengths of the putty and leave them to dry and cure. Then the students hang various masses from the ends until the lengths break. I also make balls out of the putty so they can see that it bounces and deforms. The teachers are quite happy with this.
Hope this helps.
