okay, so i'm supposed to be writing your reports but this is more interesting....
think about parachute design.
post links to interesting sites about parachutes.
add links to sites with good templates for making parachutes.
think about today's lesson on calculating the area of a circle using pi. can you find similarities between some of the diagrams here and what we covered??? see the image above. do you see what i meant about a square or circle cut out might not make a very effective parachute canopy?we can use the big white plastic rubbish bags as a source of material to make parachute canopies.
