TECHNOLOGY UNIT PLANNER Group Name: The Always Better Than You
Project Title: Move It!  Group Members: Nicholas T, Jacob Hill, Sam Carrodus
Group Roles:   Designer: Jacob Prototype Builder: Sam Google Docs Guru: Nick
DESCRIPTION OF CONTEXT:  Investigating ways of transferring energy to cause movement in vehicles
BRIEF:
Mangonel
To build a device to shoot a table­ tennis ball over a barrier, the height being increased after each round. You are only allowed to hold the ball before ‘firing’, you must not hold the frame of the device and neither may it be taped to the floor. Only one person from a team is permitted to hold and fire the mangonel. You will be allowed one attempt at each barrier height, so your device must be reliable and also sufficiently robust to last several rounds.

Assessment – SOLO Rubric  (see below)
Prior Knowledge needed:
How are forces used in the real world to create this type of movement? (provide examples and/or drawings from what you already know)
  • Gravity eg. When the table tennis ball is thrown up in the air, gravity will bring the tennis ball back down
  • Momentum eg. When launching the ball, it needs enough momentum to fly past the barrier
  • Air resistance eg. If it’s Head wind the air might push the table tennis ball back
  • Thrust eg. When launching the table tennis ball, it needs to be thrusted hard enough to go past the barrier




Resources required: Date completed 9.9.15

  • 4 Rubber Bands | Nicholas
  • 10 Plastic Drinking Straws | Nicholas
  • 10 Ice-block / Popsicle Sticks | Sam?
  • 2 A4 Pieces Of Card | Supplied?
  • 2 Skewers | Supplied?
  • 1 10m roll of 15mm Sticky Tape | Supplied
  • Scissors | Supplied





KEY FOCUS:      Follow the Technological Process
  1. Ask
    1. What is the goal?
    2. Why must we create this technology?
  2. Imagine
    1. What will the technology look like?
    2. What kind of research should we do?
  3. Plan
    1. How can we achieve the goal?
  4. Create
    1. Build a prototype(first design) and observe if problems occur.
  5. Improve
    1. Generate  solutions/fixes to the original prototype
    2. Evaluate how successful your design was.

First Trial Notes

We created but it broke immediately



Refinements Needed

Needs to be more stable
Date completed

7.9.15
Second Trial Notes



We had built it but it broke when we
launched it.





Refinements Needed



Date Completed

14.9.15
Final Trial Notes

We had built it but it broke when we
launched it.


How successful was our design?

Not successful because we didn't launch

Date Completed
How well did the members of our team work?
You have $300 to award to the members of your team according to:
  • the effort they put in to making your team work well
  • the effort they put in to helping your challenge to be successful.
Allocate the $300 amongst your team according to this criteria.

Name
$$ earned
Reason
1. Sam
$100
Because Sam helped his team mates (Gonna build it)
2.Nick
$100
He made the doc and did the presentation
3.Jacob
$100
Because he made the Plans

Apply the technological design process to solve our technology challenge.
SOLO Functional Rubric




Apply the technological design process to solve our technology challenge.

Effective Strategies to use:
1. Ask
What is the goal?
Why must we create this technology?
2. Imagine
What will the technology look like?
What kind of research should we do?
3. Plan
How can we achieve the goal? Design your prototype
4. Create
Build a prototype(first design) and observe if problems occur.
5. Improve
Generate solutions/fixes to the original prototype
Evaluate how successful your design was.
I need help to apply the technological design process to solve our technology challenge.
I can apply the technological design process to solve our technology challenge if I am prompted or directed.
I use several strategies to apply the technological design process to solve our technology challenge but I am not sure when and or why to use them.
(trial and error – aware of strategies but not sure why or when to use them so makes mistakes)

I use several strategies to apply the technological design process to solve our technology challenge and I know when and why to use them.
(strategic or purposeful use of strategies – knows why and when ).
I use several strategies to apply the technological design process to solve our technology challenge and I know when and why to use them.
I act as a role model for others to help them apply the technological design process to solve our technology challenge

I seek feedback on how to improve how I can apply the technological design process to solve our technology challenge.

                   How jet engines work
Jet engines belong on planes and it would be dangerous putting them on other things as they are so powerful that you would hurt yourself  now lets learn how they work.


                                                                                                                                                                      Jet engines use more fuel than a propeller power engine.
the air is compressed and sprayed with fuel  and then lit with an electric spark.
The gasses (the compressed and fuel)expand and blast out of nozzle at the back of the engine blasting it forward That creates thrust.


Jet engines have developed over time and are used in travelling planes and the jet engines is faster then a propeller power plane

Jet engines are like gas turbines.                                                                                                         Like piston engines their power comes from burning fuel.                                                                     The difference is that they burn fuel continuously to spin the blades.

Jets are probably the best engine for a plane because small,fast and quiet
