Answer:
PAPER CLIPS ON NOSE OF A PAPER AIRPLANE
Purpose: To determine if the number of paperclips on the nose of a paper airplane affects the velocity and speed, measured in meters per seconds.
Make a Hypothesis Based on the Learning Thus Far: If the number of paperclips on the nose of a paper airplane increases, then the speed will _increase______ (increase, decrease, stay the same) in a __linear_______ (linear, exponential, logarithmic) mathematical relationship, and the velocity will (increase, decrease, stay the same) in a __exponential____ (linear, exponential, logarithmic) mathematical relationship. (Fill in the appropriate words for your hypothesis.)
Pictures: Insert at least 3 pictures of yourself conducting the experiment into this lab report. At least 2 pictures must show your face as you conduct the investigation. You may need to ask someone to help take these photos.

Graph: Make a line graph of average Speed and Velocity (as two different lines) on the y-axis and the number of paper clips on the x-axis. Do NOT connect the dots. Instead, make a line/curve of best fit for the speed and velocity to help determine if there is a relationship between the number of paperclips and speed/velocity.
Data Analysis: This section is also known as “Show Your Work”. Here is where you show how you performed the mathematics of the experiment. Be sure to include units in your measurements. This is also where you will find the slope of the line for your graph (in decimal form including units) as well as the equation of the line IF the relationship between the dots is in fact a line.
Based on your current understanding of physics, hypothesize what forces acted on the airplane and how did the addition of paperclips change those forces? How did those forces change from when the airplane was released to when it came to rest on the floor? Draw a FBD.
Conclusion: This is a series of several paragraphs written with correct grammar using a formal academic author voice that answers the following questions:
What was the independent variable? What was the dependent
variable? What were the controlled variables? How well was the purpose achieved? What was the relationship between variables? How accurate was the hypothesis?
Why was the hypothesis correct/incorrect? What events in the experiment were expected? What events in the experiment were not expected? What human error occurred (i.e. measurement errors, significant digit errors, mathematical errors, etc)? What equipment error occurred (i.e. friction, air resistance, improper calibration, broken equipment, etc)? How could the lab be improved? How could this lab apply to physics in the real world?
What similar experiment could be done next to further study this phenomenon? What would be the independent, dependent and control variables? What would the purpose be? What is the hypothesis concerning the relationship between the dependent and independent variables in this experiment?
