2. How does launch angle affect travel distance of a rocket?
Question:
How does launch angle affect travel distance of a rocket?

3. Hypothesis:
If the launch angle (increases, decreases), the distance the rocket travels(increases, decreases)

4. How the rocket works
These rockets are air powered. Parts include: -nose cone -rocket -launch pad -angle wedges\ -cap -air pump

5. SHOULD be specific-anyone can follow it SHOULD contain ALL directions
Procedure
SHOULD be step-by step
SHOULD be specific-anyone can follow it
SHOULD contain ALL directions

6. Sample Procedure
Set up rocket as demonstrated by teacher-make sure cap is on launch tube.
Place a wedge in launch pad to set launch angle.
Make sure that your launch pad is in correct location and position (constant).
Wait for launch countdown.
Use bicycle pump to add air to rocket until it launches.
Wait for “all clear” and measure distance with trundle wheel.
Record distance in data table.
Reset rocket for trial 2.
Repeat steps 1-8 for all trials.
Test 3 different launch angles using steps 1-9.

7. Data Table Launch Angle Distance (ft) Trial 1 Trial 2 Trial 3
Average (ft)

8. Graphs What makes a graph different than a data table?
Graphs should include both the independent variable (on X axis) and dependent
variable (on y axis)
Graphs also need to include: (see rubric)
-a title
-both x and y axes labeled
-units for measurements
How do we know when to use a line graph versus a bar graph?

9. Sharing of Data Whiteboard should contain: Question
Claim (answer to your question)
Evidence (Data)
Justification (information in text to support your evidence)

10. Lab Report
Should Contain: Paragraph 1: Describe what you were trying to find out: include your question and hypothesis Paragraph 2: Overview of procedure-what you did to test your hypothesis, include your constants Paragraph 3: Data Analysis-what does your data tell you? Are there any trends? Conclusion-was hypothesis correct? What did you learn (use evidence from the experiment)? What are some other experiments you could do to learn more? Any sources of error?

11. Sample Lab Report-Paragraph 1
In science class, we were investigating the question: How does launch angle affect the travel distance of a rocket? Using my prior knowledge about how objects move through the air, I expect to see that the rocket will travel the furthest with the smallest launch angle.

12. Sample Lab Report-2nd Paragraph
To test my hypothesis, I tested three different launch angles. Each launch, I set the angle and used the tire pump to launch the rockets once the "All clear" was given. Our team sent a tracker to locate the rocket and then measured, using a trundle wheel, the distance that the rocket traveled. After three launches I switched the angle and repeated three more trials using the same procedure. Then I tested my last angle in the same way. I kept my equipment, the testing location, testing conditions and the launch site the same to produce valid results.

13. Sample Lab Report-3rd paragraph
After testing, I found the average of the distance traveled by the rocket for each launch angle. I used the average to create a bar graph showing my data. I found that my hypothesis was incorrect. The launch angle of 30 degrees did not launch the rocket as far as the launch angle of 45 degrees. The average distances that the rocket traveled are 30: 24 feet, 45°: 53 feet, 55°: 33 feet. From my discussion with other groups about their data, I found that they also observed the rocket traveling the furthest with a 45 degree launch angle which confirms my data.
