Experiment 2 Parachute Shape Problem Does the shape

Experiment #2: Parachute Shape

Problem Does the shape of a parachute affect the rate it falls?

Hypothesis: l Hypothesis: If…Then…

Introduction: l Facts about what you already know. Don’t forget to make connections here. (Should be about 5 sentences in length)

Materials l Create a complete list of materials that you will need to conduct the experiment. Make sure you include the amount of each material.

Procedure o You will write up your own procedure. o You must take into consideration the following information when writing your procedure: o The size (square area) of each parachute must be the same.

o You will test 3 different shapes. o You will draw a diagram of each of your parachutes (include dimensions of each). Circle-50 cm area= pi r 2 =1962. 5 cm 2 Square-area=s 2=1962. 5 cm 2 s=44. 3 cm Triangle-area=1/2 bh=1962. 5 cm 2 b=62. 65 cm h=62. 65 cm o You will calculate the speed and average speed for each shape of parachute. o You must drop each shape parachute 10 times.

o All variables other than shape must be kept constant: Same weight, same drop height, same length, same # & type of shroud lines, etc.

l Data: You develop your own data table that suits the needs of the data you plan to collect. Look at the last 3 experiments if you need some ideas.

Results: (graph) o Sketch a graph to best represent your data. •

l Conclusion: My hypothesis was…………. Restate hypothesis with results

l· Analysis: What did you learn that would help your design? Unusual events? Further questions? l
