My daughter was asked to prepare a model explaining the Pythagoras Theorem.
Teachers instruction was it has to be made from acrylic sheets and fill it with different colored liquid having different density.
Now making something using transparent acrylic sheet was not possible at home. Because we don’t have any such tools available at home.
After a lot of effort to convince my dear daughter that this is not going to work for us, we finally agreed that we will do it with old cardboard boxes and thermacoal balls.
So we cut three mountboard of size 3″ by 3″ , 4 ” by 4″ and 5″ by 5″ . We made these into boxes by covering the top of boxes with transparency sheets.
And filled 5″x 5″ box with colorful thermacoal balls.
We made a triangle of side 3″ x 4″ x 5″ using an old thermacoal sheet.
This fitted perfectly in the center.
When you tilt the assembly so that 5″ by 5″ box is on top, all the thermacoal balls from bigger box will fill the smaller boxes.
When you reverse it. The bigger box 5″ by 5″ will be down. And it will get filled by thermacoal balls from other two boxes.
This simple toy explained the functionality of Pythagoras Theorem beautifully and her teacher was very happy.
She literally forgot about her instruction about using acrylic sheets.
And asked all other students to build a similar kind model.
