Inspired by an illustration in our book 'One Plastic Bag' by Isatou Ceesay, we took on the challenge to design and make a new cup.
Our first stage was to collect ideas for what a cup could be made out of, investigate those materials and decide which would be best to make a prototype out of.
We didn't think a potato cup was a good idea, so we didn't take it any further.
The most popular material in the class was Lego because it's waterproof; but can you make a cup out of it?
Next we planned, made and tested our prototype.
Oh no! Lego bricks are plastic, which is waterproof, but when they make a cup...it leaks! There must be little gaps between the bricks. Back to the drawing board to re-think.
Our new cup was made of clay: there were no gaps and no leaks.
What could you make a cup out of?
