Grade 4

Make your own toys

Module 9

A fax from supertoy

A FAX FROM SUPERTOY

Activity 1

To identify a problem and accept a design commission [lo 1.1, 1.4, 1.6]

Read the following fax and then write down Supertoy’s design proposal in one sentence.

TO: Technology design team

FROM: Supertoy

TOPIC : Toys for primary school children

This year the emphasis is on practical (simple) toys that children can make themselves to play with at home. We would like you to make and improve the following two products that we have designed tentatively. Please note that they should be affordable and attractive. Use only the materials that are supplied:

Hats

Materials : Paper/carton, scissors, stapler, glue, split pin.

Help line : Information on the six most popular hats for children is supplied.

Rowing boat

Materials : 1 litre milk carton, sticky tape/glue, two (ice cream) sticks

Help line : Elastic bands, stapler, scissors.

Thanks to your team for accepting the contract. Contact us within two months.

Yours sincerely

H. Toybee

Help line

Fortunately Supertoy supplied the following six ideas. Ask for their help line. Study the following two pages for more information.

Be sure that you know how each hat is designed.

Does it comply with the three specifications (1.2) of the firm?

Activity 3

To investigate the different kinds of hats [lo 1.3]

A( A birthday hat

b) Flower hat

c) Crown

d) Cap

e) Fez

f) Helmet

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;

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies the main design aspect (e.g. who it is for, what is it for, what it looks like) that make them suitable as a solution;

1.3 performs, where appropriate, scientific investigations about concepts relevant to a problem, need or opportunity using science process skills;

1.4 writes or communicates, with assistance, a short and clear statement (design brief) for the development of a product for a given purpose;

1.6 chooses one of these solutions, giving reasons for the choice.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
