The Project:
We are to make a structure at home with some or all of the equipment listed below that will be a platform on which the weight of one full of water 2 litre plastic milk bottle will be placed ( which equals 2 kg) supported 5-10 centimetres off the table without it collapsing. The picture of the tetrahedron shape on the back of this sheet is to remind them of ideas discussed and demonstrated in the classroom about the strength and rigidity of the triangle as a basic supporting shape to base their structure on.
Equipment
12 Plastic drinking straws,
1 metre of cellotape or masking tape.
1 of the 3 strips found in a fresh packet of Blutac,
1 empty clean 2 litre plastic milk bottle cut up so as to provide sheets of plastic of various sizes.
The structures are not to be brought to school until Friday May 25 where each will be tested to see if they meet the specifications and equipment limitations outlined above and does indeed support 2 kg of weight in the form of a full of water2L plastic milk bottle. The equipment allowed does not all have to be used but no more than the total equipment will be allowed.
I decided to work with Sabre on the project so she came to my house on Saturday. When it was done we put a 2L milk bottle on top and it worked! YAY!
