PRESENTATION OUTLINE
I decided to go to Mars because it is the closest planet to the earth, out of all the planets Mars has the closest temperature to Earth's, and it does not have gases or any chemicals on its surface. Therefore making it the most suitable planet for humans.

The 3 parts of my team's parachute are the canopy,the suspension line,and the load (a bulldog clip). The canopy catches air which causes drag which makes it have a slower drop time. The suspension lines create more room for air to catch in the canopy. The load weighs down the parachute which causes more air resistance.
My team and I decided that a supply room, control room, hatch engine room, boosters, fuel canisters,crew's quarters, a food storage, and a emergency parachute were all key components our space craft requires.
FIRST TEST: SIZE OF CANOPY
OUR GROUP TESTED THE MIDIUM AND LARGE CANOPY AND THE LARGEST CANOPY HAD THE SLOWEST TIME
SECOND TEST:LENGTH OF STRING
OUR GROUP TESTED THE MIDIUM STRING (13 IN.)BUT WE FOUND OUT THAT THE BIGGEST STRING HAD THE SLOWEST TIME (AVERAGE OF 2:10
THIRD TEST:MATERIAL OF PARACHUTE
OUR GROUP USED A PLASTIC BAG WHICH WAS THE SLOWEST DROP TIME (PLASIC BAG AVERAGE 3.01)
Our final parachute had a large plastic bag as a canopy, 7in. Suspension lines. Dropping results: Trial one:3.30 trial two:2.38 trial three:3.03 average 2.90. Average drop speed 3.44 ft per sec.
IF I MADE ANOTHER PARACHUTE I WOULD USE...
- A extra large plastic bag as my canopy
- 28 in. Suspension lines
- A little bit heavier load
- A higher drop

Throughout the last two months our class learned about air resistance and all about how air effects items dropping. We first created a rocket to get to Mars. All of the students put key components into there rocket like engines and boosters. I learned to think like a designer and think of necessary items for certain tasks. We next learned about how air takes up space which led to the class creating 3 test parachutes then 1 mission parachute. I figured that size of the canopy of a parachute and the suspension lines of a parachute matter. If the canopy is large it catches more air which causes the parachute to have a slower drop time. The length of the suspension lines matters because if it's bigger it causes it to open wider causing the canopy to catch more air which causes it to have a slower drop time. Over all, I've learned a lot from this science unit and can't wait until our next unit.
