2. Methods

2.1 Materials 

Balsa wood (30 pieces)
Bungee Cord (1 piece, 1.4 meters)
Cyanoacrylate Glue (4 tubes)
PVC pipes (5   30cm, 4   23cm, 4   20cm, 2   55cm, 2   10cm)
PVC pipe joints (5 “T” joints and 6 “L” joints)



2.2 Diagrams of the experimental setup

2.3 Procedures: Detail all procedures and experimental design to be used for data collection

1.    Make the glider launcher with the PVC pipe
2.    Attach Bungee cord
3.    Use a spring balance to measure 4kg of weight
4.    Mark the 4kg mark
5.    Make 6 different gliders all with different wing designs (Figure 2)
6.    Make a fuselage that is the same dimensions and shape
7.    Launch it with a launcher at 1 meter above the field at a 5-degree angle towards the field
8.    Measure distance with a measuring tape
9.    Repeat steps 2-3 three times
10.  Repeat steps 2,3,4 with 5 different gliders




2.4 Data Analysis: Describe the procedures you will use to analyze the data/results. 

11.    Tabulate the data and calculate the average distance for all 6 gliders
12.    Plot a histogram of the average distance the glider flew against the type of wing design
13.    From the histogram, we can find out which wing design gives the furthest range.

2.5 Risk Assessment and Management table 

Problems: Someone may get hit by the glider while we are testing it.  (High)
Solution:  We should allocate an area where people are not allowed to enter it to keep them from                         getting hit.

Problem: We may hurt ourselves when we are making our glider as we are making it out of wood                        which may cause us to get a splinter. (Medium)
Solution: We should use sandpaper to smoothen the cut edges when we are handling the wood or                        when we are making the glider.

Problem: When we use a pen knife to cut the wood, we may cut ourselves while handing the                                penknife. (Medium)
Solution: We should cut the balsa wood with a proper penknife and cut the balsa wood on a cutting                    mat.

Problem: The rubber cord may hit someone when we are arming the launchpad (Low)
Solution: Make sure no one hand is on the launchpad in front of the launchpad when we are arming                    it.
