Modelling lesson 1

Modelling - lesson 1

Your tasks for the lesson!

1.  Work through Activity 1 and Activity 2 tasks. Use Google drawing instead of Popplet!

2.  On a new Blog post for today, titled the same as this, write the following (or put it on a correctly shared and linked Google doc):

Explain what a computer model is.

Give some examples of where they are used.

Share and link your Google drawing mind map to your Blog post.

Add in a screenshot of your work using the flight simulation (either directly to your blog post or on a shared & linked Google doc).

Evaluate the flight simulation (good and bad features, how realistic it was, how easy to fly, etc) and say whether you think it has prepared you for flying a real plane.

I have made these tasks coloured so that they link in with goldsilver and bronze so you can see which are the most challenging tasks.  Challenge yourself!

Publish your post when you have finished!

Problem-solving extension

Computers were invented when there was a problem that humans needed to solve - think about why Stonehenge was built, why Charles Babbage built his Difference engine, why Alan Turing built his 'Colossus' computer.

1.  On a new Blog post, titled the same as this post, explain, in your own words why computers are invented and give details of one of the examples I've given above.

2.  Go to the website below and then follow the instructions on this post, written under the link

Here is the list of problems from this webpage that I want you to work through. 

Read through these problems in turn. Choose one from the list below, write the title of it on your blog post for today's lesson and, underneath the title, describe how you would sort out/solve the problem.  You can draw the answer in Google Drawing if it's easy but remember to share correctly and paste the link to your post.

When you've done one, choose another from the list and repeat the process. Make sure you do one of each type; visual, lateral and logical

I am happy for you to share ideas with the person next to you but you must each write up your own Blog post

List of problems to work out (you may not get through all of them in the lesson)

Visual - On the lawn
Lateral - Lift off
Logical - Car wash
Lateral - Half full or half empty
Visual - Pig pen
Logical - Socks
Lateral - A moment in time
Visual - Upside down
Logical - Paper thin

I shall be interested in your answers as I haven't worked out some of them for myself yet!

Remember to make sure it's detailed enough for me to understand! And don't forget to Publish your post before the lesson ends!

Problem solving lesson 5

Problem solving group work lesson

When you have solved the three problems you've been given, and they've been checked by me, you need to write the following work on today's Blog post..

1.  Describe, in detail, each problem you had to solve, in the order you did them.
2. What was your answer to the Suspicious Death and how was it done?  What clues drew you to this conclusion?
3.  Describe how your group worked: was there one person taking charge, did you all play your part and contribute ideas, was it quicker to work in a group or do you think you'd have solved them faster on your own?

Flow charts - problem-solving lesson 3 sequencing

Today's work

1. Start a new Blog post titled the same as this one.

2. Write this on your post for this lesson....

Lots of problems can be solved by describing the solution as a sequence of instructions.   Computers can follow a sequence of instructions which makes them very useful for solving problems.

3. Explain what the word 'algorithm' means.

4. In Google Drawing, draw your flow chart for a making a jam sandwich.

5. Share your drawing (Anyone at Cooper School with the link) and copy the hyperlink.

6. Paste the hyperlink to your Blog post.

Divide and Conquer - Survival

Survival on a deserted island

Your plane crashed into the sea and you are washed ashore on a deserted island with a few school friends.  You are the only survivors.

  1. Form groups of 3 or 4 (you don't have to be sitting next to each other).
  2. Choose a lead person who then opens a Google drawing and shares it with the others.
  3. Lead person draws on the first 2 lines of the survival problem tree.
  4. Decide who is going to solve each problem.  Each person then adds a text box under their problem and writes how they could solve it.
You washed ashore with your rucksack containing the following items:
  • a notebook (now soggy!) and a pen
  • a bag of Haribos, Skittles and some biscuits.
  • mobile phone (now dead)
  • packed lunch box and plastic cutlery
  • drinks bottle
  • hoodie (now soggy)
  • first aid kit.
Blog work
  • Share your drawing again to anyone with the link and copy/paste it to a new post titled the same as this one.
  • Under your link, explain how 'divide and conquer' can be used to solve problems quickly and efficiently.
