Experiment #2: Parachute Shape
2
Problem Does the shape of a parachute affect the rate it falls?
3
Hypothesis: Hypothesis: If…Then…
4
Introduction: Facts about what you already know. Don’t forget to make connections here. (Should be about 5 sentences in length)
5
Materials Create a complete list of materials that you will need to conduct the experiment. Make sure you include the amount of each material.
6
Procedure You will write up your own procedure.
You must take into consideration the following information when writing your procedure: The size (square area) of each parachute must be the same.
7
You will test 3 different shapes.
You will draw a diagram of each of your parachutes (include dimensions of each). Circle-50cm area= pi r2 = cm2 Square-area=s2= cm2 s=44.3 cm Triangle-area=1/2bh=1962.5cm2 b=62.65cm h=62.65cm You will calculate the speed and average speed for each shape of parachute. You must drop each shape parachute 10 times.
8
All variables other than shape must be kept constant: Same weight, same drop height, same length, same # & type of shroud lines, etc.
9
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.
10
Results:(graph) Sketch a graph to best represent your data.
11
Conclusion: My hypothesis was…………. Restate hypothesis with results
12
· Analysis:. What did you learn that would help your design
· Analysis: What did you learn that would help your design? Unusual events? Further questions?
