Year 2 have been looking at different types of materials and asked themselves the question...Can a material change it'shape?
First of all they made predictions as a group by looking at a range of different objects made from different materials. Could these materials change their shape if they were ....squashed...bent....twisted or .....stretched? They createda fair test by keeping the materials the same and the type of forces they were to use.
Then the fun began!!!!!
Metal cans needed some serious force to change their shape!
Results were recorded using a table
What can you do with a towel?
Shamir says you can twist it.
You can squash Blu tac.
Iusua says you can also squash a towel.
The results were building nicely.
Cor! You can definitely stretch a rubber band! Careful!!
Now what can i do with a paper straw?
The meatl pipe cleaner could really twista nd bend!
Sahrmake had great fun twisting and bending his metal paper clip.
"Nope!" says Ibrahim ...you cant stretch a ruler!
Year 2's conclusion... some materials can definitely change there shape but it often depended on how much more you had to apply.
