Session 5: Making Machines

  • Understanding the session: Exploration of the mechanics of simple machines, this is achieved through a practical based lesson where the student will build different types of “toys” using basic mechanics.
  • The session is broken down into 3 manageable sections
  • Section A:Design, Build, & Make it go
  • Section B: Gears, Cranks, crankshafts and belts
  • Section C: Using Motors to produce motion
slide70

Activity 5A: Rolling Kit

  • Goal: To allow students to become more familiar with the ideas behind basic mechanics, how energy can be stored, transferred and transformed.
  • Outcome: Make a “Rolling toy which can travel 1-1.5 metres as an introduction to mechanical engineering.
  • Preparation: To do this you will need “One Rolling Kit” per student
  • Materials required:
  • 1 film canister with lid, with holes(8mm – 10mm Ø) drilled in both ends (this is the part where your “nice” to the technology teachers and ask to borrow a cordless drill)
  • 2 Rubber bands 6.5cm
  • 2 small washers
  • 1 piece of thick drinking straw (try Macdonalds or Burger King)
  • (note: The film canisters can usually be obtained from any photo processing agent, just ask they have loads (and they don’t want them)
slide71

Note: If you can’t

get the film

Canisters,

empty cans of coke

Fanta etc

work just as well

slide72

Now for the good news..

Its YOUR turn to make

the Rolling Kit!

slide73

Activity 5B: Gears, Cranks, Crankshafts & Belts

Goal: Familiarise students with mechanical engineering concepts so that they can try to apply them in various projects or designs. Encourage students to find out where they can get more information on mechanisms and mechanical devices, e.g. web sites, this would also be an ideal time for you (the teacher) to invite a “guest speaker” to talk to the class

Outcome: to design & build a “crankshaft” which could then be transformed into a small toy.

Activity 11A: Build a Prototype

Goal: What is a prototype? What is the point of building one? Understand what a prototype teaches.

Mentors may be involved at this stage. Prototypes are still part of the experimental stage, but provide opportunities for testing critical aspects of an idea.

slide100

Choose a realistic & achievable project

  • At this stage it is important to remind the students that they will have to actually design and build their idea
  • Many students may come up with “fantastic ideas” e.g.
  • To design self ironing clothes,
  • To design a robot to make their bed.
  • But do they really have the skills or equipment available to this this?
slide101

11A: Prototype planning

  • As a general rule, it is recommended that three basic concepts be followed:
  • investigation to see whether the right approach is being taken;
  • refinement to build on the comments and feedback after the investigative prototype;
  • consolidation to fully satisfy the objectives of the prototype
slide103

Basic Concept

  • We are going to build a prototype of a “thing” to meet specifications.
  • What are the requirements of a “thing” that will allow you to eat ice cream? List.
  • It must …
  • It should…
  • It will have to…
  • Let’s look at some examples 
slide104

Review examples and models

What design additions are NOT linked to the spoon itself but add value? Is the colour or material relevant?

What kind of spoons are these? What are they designed to do?

slide106

What is going on here?

Novelty or brilliance? Ideas that catch on or fade away to antique shelves? Are these ideas still around?

slide107

Review objects as they change over time, how materials are used, how they meet special needs, and where ethnicity plays a part in design. What other objects could be used to help students understand this?

slide108

Prototype Materials

Goal: Students try to decide what types of materials will be best suited to their project design e.g. durable, light weight, water proof etc

Outcome: By becoming familiar with a variety of different materials and their properties students can make more informed decisions as to which materials to use

Preparation: Basically this will consist of a “scavenger Hunt” ask students to bring in examples of various materials also try to encourage cross curricular links between different depts in your school.. Eg wood work, metal work , art etc…

Points to keep in mind when selecting the material for a prototype

  • Will it serve the required purpose
  • Is it cost effective
  • Is it readily available
  • Is it environmentally friendly/ recyclable
  • Is it easy to work with(shape/form)
slide110

Session 11C: Prototype,

Develop it!

  • Review our Requirements for SPOON prototype
  • Define the specifications
    • Must hold liquid
    • Must have a handle
    • Must get ice cream to your mouth five times
    • Must hold together – stay secure
    • No noticeable fatigue or decomposition
    • Must use more than two different materials

Build your prototype!

slide111

Section 11 Summary

  • By calling on previous sections of the D&D course try to
  • come up with a design idea
  • Give your design some basic specifications which must be
  • met
  • Make some rough sketches of your project
  • Decide on suitable materials
  • Test prototype to see if it meets design requirements,
  • if not.. Why not?
  • Remember,at this stage, you are only building a basic
  • prototype .. NOT a finished product
slide112

Section 12: Develop & Test

12A: Evaluate prototype suitability to specifications

12B: Test It

12C: Final Evaluation & Revisions

slide113

Session 12A: Develop it!

  • Goal: Continue to work on and develop your prototype.Ask the following questions
  • Are there anyways to improve it? e.g.do you think the materials you selected are effective,
  • what about the colour,
  • Does it look/feel “User Friendly”
  • Is there any aspect which could be improved?
slide114

12 B: Test it!

Goal: Develop your prototype, now that you see it built, is there room for improvement? Could it be bigger, smaller lighter etc

Outcome: By continuing to test and modify your final design you should end up with a fully function prototype, which meets the design specifications

slide115

Procedure:

Ask the students to evaluate each others projects

Students must try to point out 3 positive aspects & 3 negative aspects of the project they are evaluating

Allow “original designers” to take this information on board

Investigate if any of the negative aspects can be remedied

slide116

12C: Evaluation & Revision

Goal: Using the information obtained from positive & negative feedback, students revisit the prototype and try to solve any design faults

Outcome: Students should now reach the stage whereby they have developed a fully functioning prototype

Procedure: Students should continually refer to their design specifications & feed back to try and improve on any inconsistencies where possible (use worksheet on session 12C)

slide117

Session 13: Final Presentation

  • Goal: Understand the importance of presenting projects and presentation choices. Be able to determine what type of fair your students will host.
  • Transition Year Showcase
    • Parents and community members
    • Students present projects
    • Guest provide feedback
  • Mini-Engineering Display
    • Younger students and peers
    • Projects displayed
    • Engineering activities
  • Young Scientist/SciFest (I.T. Tallaght)
    • Science competition in R.D.S.
    • N.B. Closing date for entries is TBA
    • SciFest I.T.Tallaght 28th April
slide119

Sharing Expertise

  • The purpose of Solutions Showcase and the Mini-Engineering Display:
  • To recognize students\' hard work and celebrate their accomplishments
  • To share engineering expertise with others (peers, family, community, younger students)
  • To get feedback on their projects: display boards, prototypes, and presentations
slide120

Final Thoughts – The Curriculum

  • Nurtures students’ interests – allowing them to take ownership of the challenge and solution.
  • Provides a continuous and coherent path of learning,
  • that builds onto each session
  • Connects experiences like field trips and guest speakers
  • together, making sense of them in a larger framework of
  • learning.
  • Tries to encourage students to develop an intrinsic interest
  • in the subject
slide121

Final Thoughts – The Training

  • Training is always a compressed version of what you need to take back and implement. Your compressed experience will expand and grow with your students!
  • You can’t always be the expert in this day and age. Your strength lies in the ability to have faith in their ability to learn, and your willingness to learn alongside them.
