Grade 4

My own pop-up card

Module 15

Sam’s pop-up card

Activity 1

To apply the technological process completely [lo 1.1]

In this learning unit you are going to research pop-up cards (1.1), design (1.2), make (1.3) and evaluate (1.4) them.

  • Research

A What is The Need?

First you have to determine the need, submit a design proposal and analyse the problem further, and then compile the final specifications.

B Make a proposal that you will design

I’m going to design a ……………………………………….. (type of card) for

…………………………………………………………..(user) to use in or at the

………………………………………… (place) for ……………………………….

……………………………………………………………………………..(use of).

C Analyse the problem further

The following W-questions will help a lot. Ask your own questions as well.

D Compile a list of specifications

Consider the following:

  • How big must the card be?
  • What materials am I going to use?
  • Which will be the cheapest ?
  • How will I manage to make it within the allocated time?
  • What will it look like?
  • Will I make something creative/unique ?
  • Durability : Will the card be strong enough?
  • I must be able to make it myself .
  • What shape will it be?
  • What finishing touches will I use?
  • Will my card comply with the purpose that it was designed for?
  • Will I be able to market or sell my card?

Now you can begin to design the card!

  • Design

A Discuss your ideas again.

  • Think on paper. More possibilities will give you a better chance of finding a good solution.
  • It is unlikely that your very first idea will be the best. Try to draw at least THREE possible solutions (ideas).

B Decide on your best idea!

Hints

  • Communicate your ideas. Ensure that it complies with your design proposal.
  • Make free-hand sketches with annotations. Change constantly.

Ask critical questions while you draw:

  • Can it be simpler ?
  • Which moving parts will there be?
  • How will I connect the different parts?
  • Am I using the best materials ?
  • Is it affordable ?
  • What does it look like?
  • Can I make it myself ? (In time?)

Make neat final drawings and decorate them in colour. You may use drawing tools.

  • Make

How to make a pop-up mechanism

  • Fold a white, blank A4 paper in half.
  • Make two parallel cuts in the paper.
  • Open the paper with the cut out strip forming/making a 90º angle to the inside.
  • Paste a face or any other picture on the front of the strip.

Ahow to plan

  • When you fail to plan, you plan to fail!

TIME is very important - therefore we must plan properly.

So many things need to be done at the same time, therefore you will have to organise your work in such a way that you won't waste any time and energy. We will set up a scheme so that you will utilise your time effectively. It makes your work easier. Good planning saves time and ensures a better product.

Actions Materials Tools

(i)which actions must i complete?

Tick off as soon as it is completed.

make certain parts glue
finishing touches round off
paint test
  1. Which materials will I use?

Evaluate and compare the different materials that you will use with regard to:

  • availability;
  • costs;
  • manageable or not?
  • durability;
  • colours.

(iii) Which tools will I use?

B Work safely!

Safety knife

Be very careful when you cut paper or cardboard. Use a safety ruler with the safety knife.

1.4 Evaluate your products and work

Be honest about your mistakes. Learn through it.

A First discuss the questionnaire with your partner:

Did I do good research and planning ?

……………………………………………………………………..

  • Can I handle and solve the problems that arose during the manufacturing process , easily?

…………………………………………………………………….

  • Does my card comply with its specifications ?

…………………………………………………………………….

  • What are the strong and weak points of my card?

…………………………………………………………………….

  • Will I do the same next time if I have to repeat the project?

…………………………………………………………………….

  • How can I improve my design?

…………………………………………………………………….

  • Am I satisfied with my pop-up card? Why?

……………………………………………………………………

  • What do other people think of my card?

……………………………………………………………………

  • Did I enjoy making the card?

……………………………………………………………………

  • What problems will a less privileged person possibly encounter when making the card?

……………………………………………………………………

  • What are the disadvantages of the cards?

……………………………………………………………………

Assessment

Learning outcome 1: technological processes and skills

The learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies.

Assessment standard

We know this when the learner:

1.1 finds out, with assistance, about the background context (e.g. people, environment) when given a problem, need or opportunity.
