Starburst Symmetry

Starburst SYmmetry (10)

This quick project was a fantastic way to show Travis circular symmetry, slightly different from symmetry with two halves as we’ve explored late in symmetrical socks and paper doll projects. There was a lot of need for precision with this activity, so I was proud of Travis’s concentration level.

To start, fold a coffee filter in half. Then in half again, then in half again! Travis took the task of folding and making a good crease each time quite seriously. At the end, your filter will be the shape of an ice cream cone.

Next he spritzed the filters with water until damp on each side, but not soaking.

Use marker to make dots all over the filter, counting to three for each dot. This was a great little lesson in patience and also not scribbling (as he’d done recently for a different type of coffee filter project).

Flip the filter over – wow! His pattern was waiting there on the other side.

I showed him how to go over his dots again – slowly and carefully – to make the final result a little more clear.

Now he opened it up for a big reveal. “Wow!”

He wanted to know how the pattern had gotten there, but understood once I explained that the marker went through all 6 layers of the filter, resulting in perfect symmetry in all 6 segments.

I loved how his pattern made a purple diamond, unintentinoally.

These are beautiful hung on the wall or fridge once they dry!
