Procedures
Creating
the Launcher:
1. Cut
out a (10.0 cm by 21.0 cm) plank.
2. Cut
out 2 (10.0 cm by 10.0 cm) planks to support the rubber bands
3. Tie
all 7 rubber bands together.
4. Loop
the 2 ends of the rubber band on each of the 10 by 10 planks
5. Cut
out and stick two (5.0 cm by 20.0 cm) planks to act as a guide rail for the
plane.
6. Mark
out a dash using permanent marker about 2cm from the back of the launcher. This
will act as a marker for reliable results, as the planes will be launched from
there.
7. Cut
out 2 (4.0 cm by 10.0 cm) plank and glue it at the bottom to angle the
launcher.
Creating
the Wings:
1. Create
5 different types of wings.
2. For
one, cut out an oval wing.
3. For
the second wing, create 2 triangles.
4. For
the third, create a trapezoidal wing.
5. For
the fourth, create a rectangular wing.
6. Finally,
for the last, create a combination of the rectangular and two trapezoid wings
7. Sand
them down to make more streamlined.
Creating
the Plane:
1. Cut
out the balsa wood to create the 2 pieces of the plane’s body.
2. Use
the glue gun to paste the 2 pieces together.
3. Cut
a hole to accommodate the wings of the plane.
4. Sand
down the body of the plane to make it more streamlined.
5. Repeat
this to make a total of five planes.
Gathering
of Data:
1. Put
the launcher on the table outside the Research Lab
2. Pull
back the plane to the indicator on the launcher.
3. Release
the plane
4. Measure
how far the plane has flown using a measuring tape
5. Repeat
to check for reliability
6. Check
if the planes had sustained damage when testing, and if it has, repair or make
a new glider and try again.
Data
Collation:
●
Measure distance travelled by aircraft.
●
Repeat to ensure results are reliable.
●
Put data collected onto a Google
Spreadsheet, then in table form.
●
If erroneous data is found, the error
will be identified and rectified as soon as possible.
Sorting
of Data:
●
Before collating data into a table, Each
experiment is repeated 3 times. If results are duplicable, the results will be
used. If results vary, the reason will be identified and the planes will be
remade for another trial.
●
Use a table and Graph for neater presentation
of work
●
Raw results from testing will be stored
in the logbook for future reference
2.4
Risk Assessment and Management
Identify and assess the risks involved:
●
When cutting out the wood
pieces with the help of the penknife, a finger might get cut.
●
When gluing the wood
together with the hot glue gun, the finger might touch the glue gun and get
burned and glued.
●
When bending the Balsa woods,
the finger is prone to splinters.
Describe the safety precautions and procedures that will
be used to reduce the risks:
●
We need teachers’/ lab managers’
supervision when creating the mechanism
●
Have alcohol-rubbing substance ready in
case we need to wash off the glue. Also, wear gloves to prevent burns and glue
stuck to our fingers.
●
Wear gloves when operating the Balsa wood
to reduce the chances of splinter pricking our fingers
2.5
Data Analysis
Analysis:
Analysis:
●
After experiment has been repeated three
times, the data will be reviewed to check for reliability.
●
If erroneous data is found, the error will be identified and rectified
as soon as possible.
Presentation:
●
Table and Graphs for neater presentation
of work
●
Raw results from testing will be stored
in the logbook for future reference
●
Line Graph will be used to represent the
data of the distance travelled by plane and different wing areas of gliders.
●
Also, a copy of the results will be kept
on our MacBooks in case results are lost.
