__**Cover Page**__
Should Include: Title Name Due Date Partner(s) Name(s) Course Title Teacher’s Name Class Period

Staple in the upper left corner, no plastic or cardboard covers.

__**Purpose (5 points)**__
Use the purpose provided below:

Purpose: The purpose of this lab is to find the altitude of a model rocket theoretically using Newton’s Laws of motion and experimentally using trigonometric ratios.

__**Data Table (20 points)**__
Include the following headings:

Thrust Period of thrust Mass of Rocket Mass of Engine Acceleration due to gravity Baseline distance (between observation stations)

For each observation station: Elevation angle (vertical) Azimuth angle (horizontal)

__**Spreadsheet (30 points)**__
Answers should be rounded to two decimal places. Include the following (USE FORMULAS):

Hypothetical calculations:
 * Weight of rocket plus engine
 * Acceleration for thrust phase
 * Velocity at burnout
 * Distance during thrust phase
 * Coasting time
 * Coasting distance
 * Total distance to maximum height (hypothetical rocket altitude)

Experimental calculations:


 * Altitude (using Law of Sines - station #1)
 * Altitude (using Law of Sines - station #2)


 * Average Altitude of Law of Sines from both stations


 * Percent Error (compared to the hypothetical altitude):
 * Altitude (using average of Law of Sines)

__**Spreadsheet with formulas (10 points)**__
All calculations in the spreadsheet need to use formulas in the spreadsheet.

__**Sample Calculations (20 points)**__
Include calculations and brief explanations for each item in the spreadsheet

Show formulas, substitutions, and units Use Math Type

__**Introduction (10 points):**__
• What were you trying to do/prove? • How did you do this?

__**Essay (60 points):**__
• For each stage of the rocket’s flight path, discuss: • Discuss how a rocket is designed and constructed so that it is stable and can achieve a maximum altitude
 * How Newton’s Laws and Conservation of Momentum are involved
 * Any changes in thrust, weight, mass, acceleration, drag, and velocity (and why they occur)
 * Include diagrams to enhance your explanations

__**Conclusion (50 points):**__

 * What were your results?
 * 1) How did your experimental results, and your calculated prediction compare? Explain any differences that existed.
 * 2) Analyze your errors
 * What were your percent errors between the calculated prediction and your experimental results?
 * 1) What were your sources of error, how (specifically) did they affect your results and how could they be reduced?
 * What might be your next steps, if you continued your investigation of rockets?

__**Honors Challenge:**__
Develop an area of further study beyond the basics provided above. Submit and proposal in an abstract by __________________ that addresses:


 * Question of investigation
 * Experimental design
 * Plan for reporting your finding in your lab. For example, changes to data collection, calculations, analysis, etc.
