Hexaflexagon Fun

Thanks to Twitter and YouTube, I recently came to watch Vi Hart’s videos on hexaflexagons¬†(her YouTube channel¬†has some fascinating maths in it wrapped up in some very engaging and creative videos!).

A great idea for my Year 10 Maths class. Hence the essential question for the next lesson…


And some flexagation fun ensued!

If you haven’t made one, give it a try! I found this tutorial helpful as it didn’t rely on any templates, just some logical folds.

Now I just need to get some burritos and make a hex flex mex for lunch!

Newton’s Third Law

Watch this video from ESA on Newton’s 3rd Law.

Answer the following questions in the comments (and/or your workbook):

  • Name one of the action-reaction pairs from when the astronauts push against each other
  • If they both experienced the same force, why does the astronaut carrying the heavy battery not move as fast as his colleague?
  • Why did only one student move from the end of the Newton’s Cradle?
  • What is the action-reaction pair for a rocket?

Use this quiz to check your understanding.
