Tetrahedral Kites

We just finished our unit on volume and surface area of prisms.  They wrote a test and then I wanted to do something fun as an end project.  I decided on two activities:

1.  The first one was to build a more complicated 3-D figure out of a given net.

2.  The second one was to build tetrahedral kites.  It has been a real success, the students are really into in and they just want to keep building them.  It has been a great way to help the students recognise how to build a 3-D object and learn about volume and surface area of them.  We are still working on them and planning on flying the bigger ones (photo #2) and then making one really big one and attempting to fly that.  We will be doing some calculations on surface area and volume of the different sized kites as well.  I will attach another video of flying the bigger kites next week.


Each student made 4 mini tetrahedrons and then built this kite



Out flying the kites

This is four students that put their tetraherdons together to make a bigger one.

We are currently working on putting 4 of these together to make an even bigger one.
