Flight Test Data 试飞数据
How you throw your glider will greatly affect how it will fly. Therefore, before you start conducting your experiment and recording data you should first determine how you will throw your glider.
你投掷滑翔机的方式将极大地影响它的飞行情况。因此，在你开始进行你的实验和记录数据之前，你应该先确定你将如何投掷你的滑翔机。
Before you conduct your formal experiment you will need to experiment with different ways to throw your plane and observe how the plane flies each time. At this stage of the experiment we are not concerned about recording quantitative data about the gliders flight. Instead we are looking at making qualitative observations (specifically observations about what we can see) during our practice flights.
在你进行正式的实验之前，你需要用不同的方法来投掷你的飞机，并观察每次飞机是如何飞行的。在实验的这个阶段，我们不关心记录滑翔机飞行的定量数据。相反，我们将在飞行练习中进行定性观察(特别是注意观察我们能看到的东西)。
Qualitative Data 定性数据
With your partners you must determine a minimum of 2 ways to throw your glider and then conduct test flights to determine which method will result in the best results.
你和你的小伙伴们必须确定至少2种方式来投掷你们的滑翔机，然后进行试飞，以确定哪种投掷方式最好。
Draw a diagram to illustrate how you threw your glider. Your diagram should focus on illustrating how to throw the glider properly and is not meant to be an artistic illustration. The use of labels and arrows to illustrate force and flight vectors is highly recommended.
画一张图来说明你是如何投掷滑翔机的。你的示意图应着重说明如何正确地投掷滑翔机，而不是一个艺术性的说明。强烈建议使用标签和箭头辅助说明力和飞行矢量。
Student Samples 学生作品
Describe both methods of throwing the plane that you and your group tried during the pre-testing of your glider.
请描述在滑翔机试飞期间你和你的小伙伴尝试的两种投掷飞机的方法。
Approach 1 | 方法1
Approach 2 | 方法2
Which approach to throwing your plane was the most successful? Why do you think this?
哪种投掷飞机的方法是最成功的?为什么?
Now that you have determined the most effective way of throwing your glider you are now ready to conduct your experiment and record data. It is very important that you throw your glider the exact same way each time your test your plane so that the method of launching your plane does not affect your results.
现在，既然你已经确定了最有效的投掷滑翔机的方式，所以你可以开始准备进行实验和记录数据。请记住，非常重要的一点是：每次测试飞机时，你都要以完全相同的方式投掷滑翔机，这样“飞机的发射方式”这个因素就不会影响你的测试结果。
Record all of your data from your test flights. Make sure that you include all relevant units, and maintain an appropriate number of significant figures for all measurements.
记录所有的测试数据。确保你的记录包括了所有相关的信息，并为所有的测量数据保留适当的有效数字。
| Distance / 距离 | Time / 时间 | Speed / 速度 | |
| Test 1 | |||
| Test 2 | |||
| Test 3 | |||
| Test 4 | |||
| Test 5 |
Briefly describe each test flight. Make sure your record any anomalies (i.e. glide collided with another object during flight, the tester tripped while throwing the plane).
简要描述每一次的试飞情况。确保你的记录中没有任何异常(例如，飞行时滑翔机与另一个物体相撞、测试者在投掷飞机时绊倒)。
Once you have complete your test flight calculate the “Minimum”, “Maximum”, and Averages for all of your test flights.
完成测试飞行后，计算所有测试实验中的“最小值”、“最大值”和平均值。
| Distance / 距离 | Time / 时间 | Speed / 速度 | |
| Minimum/最小值 | |||
| Maximum/最大值 | |||
| Average/平均值 |
Technical Specifications 技术规格
Draw a sketch of your airplane. The scale does not need to be perfectly accurate but your drawing should be competed using a ruler. However, your drawings must include relevant measurements (i.e. the location and position of the wing) so that future engineers can reproduce your glider’s measurements and proportions so that your experiment can be validated by future scientist.
给你的飞机画一张草图。比例尺不需要非常精确，但是你应该用直尺作图。然而，你的图纸必须包括相关的测量数据(即机翼在机身的上下位置和靠前还是靠后的位置)，这样未来的工程师才能复制你的滑翔机的测量数据和比例，这样你的实验才能被未来的科学家验证。
