1. Video: kids respond to... Old computer.
2. What's the oldest technology you have at home?
~ make a mindmap of old technology in your house (use mindmap+)
<IMPORTANT> don't work longer on this mindmap then 5 minutes!
4. Analogue & digital assignments
Before we had computers, we had machines that used data in an analog way.
Old school technology
Complete the list...
Assignment #3
Here is an example of old to new technology in five steps.
Complete this list in your document with a picture ánd the name of the object.
3. What's the oldest technology you have at home?
~ compare mindmap with your neighbour, anything in common?
Questions:
1. What kind of machine is this?
2. How did it get its information?
3. Before we had cable,
where did this machine get its information?
4. What is this?
5. How did it pick up information?
4. Analogue & Digital assignments
Assignment #1:
Put your mindmap in a Pages doc.
Give the document a title:
[ "Your name" + Old technology ]
Because you work in pairs, your teacher will receive one document per two students! At the end of this assignment you hand it in through Showbie:)
Assignment #2: answer the questions you encounter, write answers in your pages doc.
Today you will work without a teacher.
You can do this alone, but it's better and more fun to do it with a neighbour.
Use your earplugs & watch the video

electronic communication using a continuously changing signal (electronic pulse)
Analogue = older system
Digital = newer system
electronic communication using a series of numbers choosing
one
or
zero
3. A bit of science
- the 1 or 0 is called 'bit'
- eight bits form a 'byte', example: 01011101
- bytes form computerlanguage
2. A bit of science about Analogue and Digital
Some numbers to blow
your mind :)
Please send your pages document with the answers to your teacher with
showbie.
Question:
Which of these machines are analogue and which are digital? Put your answers in your
pages document!
