## Sam’s envelope (part 1)

SAM’S ENVELOPE

This is your last module of the year. First we are going to learn how to make the envelope. Then we are going to apply in a practical way everything that we have learnt during the year by making a pop-up card. In the last learning unit we are going to evaluate the year’s work.

## To determine the background of the problem [lo 1.1]

A Do the following case study and read the remarks afterwards.

• Poor Sam! He is satisfied with a little. He only asks for a birthday card. Some of you can really warm his heart by sending him a card.
• In this study unit we will learn how to make birthday cards. There are in fact a variety of other cards that we can also make: thank you cards, invitation cards, and ordinary congratulatory and welcoming cards.
• Why don't you visit a number of bookstores to see what kinds of cards are available?
• Bring a variety of cards to class and discuss them.

## To make an envelope for your invitation [lo 1.7, 1.8, 1.9]

• While you are making the envelope you will learn how to:

 measure  mark  cut  paste  stick together

• These processes are very important for making your final product. Practise them after your teacher has demonstrated them.

REMEMBER: Safety always comes first!

A Measure

Measuring tape : It is usually marked in centimetres on both sides, in opposite directions.

Ruler : A transparent ruler works best.

B Mark

Tailors' pencil : Used to mark out a pattern on dark materials. Chalk can also be used.

Tracing wheel : Used with carbon paper on materials on which markings do not show easily.

Folder : It is used to draw a clear, colourless line on cardboard so that the cardboard can be folded easily along the line. Use the folder together with a safety ruler to draw the folding lines.

C Cut

• Use sharp scissors.
• Cut with strong, regular movements
• Turn the paper and not the scissors when cutting.

D Cut cardboard

• The blade of the knife must be sharp.
• Press evenly on the paper knife while you cut alongside the ruler.
• Pull the knife lightly away from your hand towards your body on the line that you wish to cut.
• Repeat a few times. Put more pressure on the knife every time until you have made a neat cut.

Always use a safety knife to cut along a straight line. You may use scissors where the line curves.

• Safety ruler : Use a safety ruler to prevent cutting your fingers.
• Metal plate : Use one underneath the cardboard to protect the desk. E Paste

Glue : Choose the correct type for the work.

Use a plastic knife, a piece of hardboard or a small brush to apply the glue evenly.

Sticky tape : Double sided sticky tape can be used instead of glue.

Masking tape is handy to keep the cardboard in position while you're working with it.

F Paste together (cardboard or paper) - three possibilities

1. Fold one corner and paste the other one to it.

1. A slit/notch can be made on the opposite side of a thick cardboard to slot one side in.

1. Cut grooves around a cylindrical carton (toilet roll).

Push the roll through the hole in the paper.

Bend the cardboard back, glue and paste.

## 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;

• briefly outlines a plan for making, listing the main steps;

1.8 uses suitable tools and materials to make products by measuring, marking out, cutting simple forms in a variety of materials, and joining them, using a range of techniques;

1.9 works neatly and safely.

can someone help me with some logarithmic and exponential equations.
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

hello
Sherica
im all ears I need to learn
Sherica
right! what he said ⤴⤴⤴
Tamia
what is a good calculator for all algebra; would a Casio fx 260 work with all algebra equations? please name the cheapest, thanks.
a perfect square v²+2v+_
kkk nice
algebra 2 Inequalities:If equation 2 = 0 it is an open set?
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

No. 7x -4y is simplified from 4x + (3y + 3x) -7y
is it 3×y ?
J, combine like terms 7x-4y
im not good at math so would this help me
yes
Asali
I'm not good at math so would you help me
Samantha
what is the problem that i will help you to self with?
Asali
how do you translate this in Algebraic Expressions
Need to simplify the expresin. 3/7 (x+y)-1/7 (x-1)=

types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
preparation of nanomaterial
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
what is system testing
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
Azam
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
can nanotechnology change the direction of the face of the world
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.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
how did you get the value of 2000N.What calculations are needed to arrive at it
