Feedback and revision lesson

I've marked your Blogs!

Please check your Blog and my comments.

If you didn't understand the binary addition in the lesson, I've made an easier, "slowly does it", worksheet - link is below.

https://docs.google.com/a/cooper.oxon.sch.uk/spreadsheets/d/1RquvnOE-8MrVfSEGZlTTO2rFA60-evNcpXQSHr1Af3s/edit?usp=sharing

Make a copy and work through the worksheet tasks. You can then share it and paste it to a Blog post for today.

By the end of the lesson, you should must have actioned my comments and responded.

Next lesson is a test on all of Unit 10!!!!  Revise!!!!

Lesson 4 Binary images

Today's tasks

1.  Share your 2 spreadsheets (Anyone with the link) and paste the 2 links to your Blog post.

2.  Explain that images are made up of pixels in a bitmap.

3.  Explain how the number of pixels relates to the size of the image file.

4.  In terms of file size (or memory), what do the binary numbers '1' and '0' represent?

5.  Write down how many bits are in a byte, how many bytes in a kilobyte, how many kilobytes in a megabyte - in full sentences.

6.  How does the number of bits relate to the number of colours available?

Finish this for homework.  It is your STAR marked assessment!

Unit 10 Electricity and Information Lesson 2

This lesson is all about logic gates.  There are millions of these in a computer processor and they are used to make decisions.

Your work
1.  Watch the video
2.  Open Activity 1 worksheet and go to File - Make a copy.  Answer the questions on your copy of this worksheet.  Share it with me and Mr Surrall and paste the link onto your Blog post for this lesson.
3.  Open Activity 2 worksheet (in Activity 3 section!) and make a copy of it as before.  Answer the questions on your copy of this worksheet.  Share it with me and Mr Surrall and paste the link onto your Blog post for this lesson.
4.  Give your Blog post a title.
5.  Under the 2 pasted links, explain what logic gates are used for (see the teacher's presentation for hints).
6.  Write down ways you can remember which gate does what and what shape the gate is.
7.  Link this lesson to previous lessons you have done on Binary and the Processor - explain how the computer sends electronic messages around the processor using binary.
8.  Publish your Blog post at the end of the lesson.

If you don't finish this work in the lesson, please make sure it is finished for homework ready for your next lesson

Python lesson 3 Selection

This lesson is about selection where the computer will make a different response according to different results to a set of variables.

Written work 1

Print screen your Code Academy programs and paste to a Google doc as you work through those tasks.  Give this doc a sensible name.

Written work 2

You drew up a flow chart in the lesson for the following scenario: 

• A user enters their password.
• The computer checks to see if the password is correct.
• If the password is correct then they are allowed access.
• If the password is not correct then they are denied access.

Draw this flowchart on a Google presentation (it's easier to draw shapes in this application than in a doc).

Share the presentation (Anyone with the link), copy the URL and paste it to a Blog post for this lesson.  Don't forget to highlight the URL text and click on the blue Link button!

Remember to give your post a title please!

Written work 3

Below your presentation link, explain what selection is - in your own words!  You can use the teacher's presentation for lesson 3 to remind you.

Written work 4

Share your Google doc of Code Academy screenshots (Anyone with the link) and copy/paste the URL to your Blog post as well.

Now click Publish!

Well done.  Thank you :-)

Python lesson 2 - Variables

For this lesson, this is the work I need you to show on a new Blog post:

1.  Title your post the same as this one

2.  On a new Google doc (also called the same as this Blog post), paste a print screen of all your Code Academy programming for this lesson and explain what you are doing.  Talk about the variables you are using in each program.

3.  In your explanations, include notes about RAM and how it temporarily stores data.  

4.  Remember - details = marks!

5.  Share your Google doc (Anyone with the link) and paste the link to your Blog post.  Don't forget to add the blue hyperlink to it on your post!

Problem solving Lesson 2 - Building a bomb disposal robot practical

After you have had a go at making your own bomb disposal robot with the kit, you need to write up a description of how this went on your Blog post - 

*  the successes - did your group manage to do your task?

*  the failures - what didn't work, what problems were there for your group?

*  how you solved any problems, etc.  

*  how did all the groups work together to build the whole robot - successes,       failures, problems, etc?

Remember.........details = marks!


When you have finished writing up how building your kit robot went, you can then PUBLISH!!

Building a computer

This is the work you need to write up on your Blog for this lesson:

1.  Write down 3 risks of injury that could result from building a computer and how you can avoid them

2.  Write down what the following parts of a computer do:

a) Hard drive
b) Sound card
c) RAM
d) CD-Drive
e) Motherboard
f) Processor
g) Graphics card
h) Network card
i) Computer case

Just one sentence about each part will do!

The Processor

For your Blog notes you need to write about the following (use the teacher's presentation to help you):

1.  What is the computer processor?

2.  What does it do?

3.  How many tasks can the processor carry out at one time?

4.  How does it  manage to do lots of tasks?

5.  What is the speed of a processor?  How is it measured?

6.  How many instructions per second can a 1Hz processor execute?

7.  Which is faster - a 5MHz or a 2GHz processor?

Storage devices and binary

Here is the work that you need to do.  (You can look at the teacher's presentation in lesson 3 of the Building a Computer unit for help).

1.  Open a new post on your Computer Science blog and title the Post the same as this one.

2.  How do computers use binary code?

3. What numbers in binary code represent the electric current inside the computers being turned off and on (don't forget to say which is on and which is off!)

4.  Write a short description of the activity you did with torches sending messages to each other.

5.  Explain why the more "bits" that are in a code give more colours (this is from your Binary Images spreadsheet work). 

6.  Write down the information from the teacher's presentation, slide 8, explaining the different units of data storage (bits, bytes, etc).

7.  When you have done all the work above, click Publish!  :-)

8.   If you don't finish this in the lesson, you'll need to either finish it at lunchtime or at home.  Deadline is by the end of the weekend, ready for next week! 

Building a computer Lesson 2 - input and output

These are the notes you need to make on this lesson's Blog:

1.  Open Activity Sheet 2 in Lesson 2 - Horses for Courses and make sure you click 'File' - 'Make a copy' before you start working on it!  It will automatically save to your Google Drive. Complete the worksheet and leave it open until you have completed Task 4 below.

2.  Make a new post on your Computing blog and title the post the same as this Blog title.

3.  On your post you need to write:

• A definition of what hardware is and an example
• A definition of what software is and an example
• A list of the 4 types of hardware
• Any links with this lesson and previous ones?  If so, which and how do they link?

4.  Share your Horses for Courses worksheet (change Private to Anyone with the link).  Copy/paste the link address to your post.  Don't forget to highlight the link text and click on the blue Link button.

5.  When it's finished, click Publish.
