Today we looked at space materials. We were much more confident, this time, coming up with properties of materials, like opaque, brittle and transparent. We used this information to look at composite materials and to describe how their properties change.
We made our own composite material from paper. We found that adding the different shapes in our material made it much stronger.
We then did an experiment to see what shape would make he strongest material. Our predictions included:
The triangular shape will be strongest because triangles are the strongest shape. – Adam
The small circles will be best because there is more material for the weight to sit on. – Violet
The small circles will be better than the big ones because the weight will fall through. – Daniel
We found Violet’s prediction was correct because the small circles held the most weight.
