Blogg II

Climograph~

Here is the climate graph I completed... yes I know, I just love to state the obvious.

Method~
Materials:
For Launcher
Wooden base
Pair of nails (could change.. depending on what I get at Bunnings)
Elastic band/material
Plastic hook

Equipment:
Measuring Tape (measure distance travelled)
1m Ruler
stopwatch (if I am going to measure length of flight)

Method:
Plane Launcher
1. Drill pair of nails into plank of wood 15cm apart
2. Attach on end of elastic band to each nail
3. Cut a hook out of plastic (this will be used to launch plane)
[further info: designing plane launcher entry]

Airplanes
1. Follow the instructions to build the models of airplane required:
- The Arrow
- The Dart
- The Stealth
(detailed instructions on 10paperairplanes.com)

Experiment
1. Construct plane launcher using method above
2. Cut out of an A4 sheet of paper a sheet 20cm x 28cm
3. Construct the first model (The Arrow)
4. Launch the airplane, 1m from the ground and pull back to full length of board each time
5. Simultaneously, time the length of flight (from take off til landing)
6. Observe and record details of flight:
- distance travelled
- length of time travelled
7. Repeat steps 1-6 with a sheet of paper that is 1cm smaller in length and width
(ie. 19cm x 27cm, 18cm x 26cm)
8. Repeat steps 1-7 until the size of paper reaches 12cm x 20cm
9. Repeat steps 1-8 using the other two models (The Dart and The Stealth)
10. Repeat stepts 1-9 three times.

yay! finally finished for the second blog submission!
