Fold your own balancing bird

This is the video we briefly saw in class today in 3H, for your own leisure watching.

You are advised not to use dollar notes. Please find some used recycled papers instead.

And here's the video which was shown in class today.

Please take note for your physics tests and exams

For the final answers for all calculations: 

• Do not leave in fractions
• At least 2 significant figures (add a .0 to single-digit number) 
• At most 3 significant figures (round off long numbers to 3 sf) 
• Correct units are always necessary in all final answers

This applies for all physics assessment papers.

Also take note:
You are required to know the SI units and prefixes.
