Starter: Data types wordwall

1. Table and Field Planning

I would like you to begin designing your tables in detail today.  These designs will not be set in stone and can be altered at a later date if necessary.  A template for your table designs can be found in P:\Senior Pupils\ICT\GCSE\Coursework\Year 11\Project\Design – you can copy and paste this as necessary.

Points to remember

Naming conventions – Please prefix your table names with tbl_, for example a table for customers would be called tbl_customer.  As you go though your design work we will also use qry_, frm_ and rep_ – I’ll leave you to work out what they mean…  Also, when deciding on field names, avoid spaces and use capital letters.  For example, membership number becomes MembershipNumber.

Key Fields – Make sure you clearly identify the primary key field in each of your tables.  You could write (PK) after the relevant field.

For an A grade you must plan;

  • at least two tables
  • a key field for each table
  • across all tables you must have at least twelve fields
  • across all tables you must have at least four different appropriate data types
  • at least two different types of validation / data entry restrictions

remember these are the minimum requirements for an A grade – A* will require further development.

Examples

Two different design examples can be found in P:\Senior Pupils\ICT\GCSE\Coursework\Year 11\Project\Design along with their marking commentaries.

2. Validation

In the two groups that I put you in, please share your ideas for how you will validate some of your fields.  You need to have at least two different types across all your fields.  Listen carefully to what other people are saying as they might have ideas that you can use in your project.

For further help on methods of validation in Access…

Validating some of your fields will be an essential part of your project if you wish to obtain a good grade for your project.  Navigate to the access video tutorials again by clicking here and look for the validation subtitle.  You will learn about required fields (presence check), input masks and validation rules (would should be a bit of revision).

Homework

Please continue to work on your analysis if you haven’t finished this yet.

7.1 Lesson 3 Where I live – Adding Images

 Recap:

Last lesson we:

  • evaluated a presentation – saying how it could be improved and whether it was suitable and appropriate for the target audience. (Overview – see yellow sheet)
  • opened a new folder to save our presentation in. We called the folder: ‘Unit 7.1 Where I Live.’  We called our presentation…?(can you remember?). On your whiteboard write the file path for your presentation folder, e.g. My documents/…
  • started to create a presentation in outline view(why did we use this view..? can you remember?)

LEARNING OBJECTIVES

In today’s lesson you will learn how to;

  • Find suitable images for each slide
  • Be able to alter the images
  • Insert them into a presentation

 

STARTER – Image Cards

Grab a white board, pen and cloth.  Work in pairs. 

  1. Open Starter Image Cards and decide which group or groups of people would like each image.  Choose from Teenagers / Older People / Nobody / Everybody
  2. What makes some images appeal to different audiences?
  3. What makes some images unappealing?

It is important to use powerful pictures – positive images will appeal to students and their parents e.g. smiling children, all age groups. 

 

Task 1 Finding Images on the Internet

Use Google Image Search to find images of your local area.  Use keywords and the + sign to narrow your search. E.g. “Shrewsbury” + “River Severn”

 

Task 2 Collecting and Saving Images for your Presentation

  1. Collect and decide on one image for each of your slides.  NOTE: the maximum number of images allowed per slide is two.  Your images must appeal to all age groups. 
  2. When you have found a good images, right click on it and choose Save Picture As.  Give it a name you will recognise e.g. Music Hall.  Create a new folder in your Unit 7.1 Where I Live folder.  Call this subfolder Images or Pictures.  REMEMBER to save all of your images for your presentation in here. 

 

Task 3 Inserting Images into your Presentation

  1. Open the slide in which you want to insert the image. 
  2. Choose Insert / Picture / From File.  Find the Image or Picture folder.  Find the image and click Insert.  The image will appear on your slide. 

 

Task 4 Editing images

  • Crop

To cut unwanted areas off an image, open the Picture toolbar (View / Toolbars / Picture) Select the picture and choose the crop tool.  Click and drag on the picture’s selection handles to cut off the bit you don’t want.  To come out of Crop mode, click on the page away from the image. 

  • Resize

To make a picture bigger or smaller, select the picture and click and drag on a corner selection handle.  IMPORTANT if you don’t use the corner handles you will distort the image!

 

2 *’s and a wish (yellow sheet)

We are going to show our slide show to others in the class and we are going to provide  constructive criticisms – share your thoughts on the yellow sheet, but be mindful of their feelings.  Choose 2 things that you like (2 *’s)  e.g. What images do you like?  Tactfully suggest one improvement! (1 wish)

 

Task 5 (when you have finished inserting images)

What ever your personal preference for colour, font, etc, it is important that your presentation has “consistency” – the same fonts and background throughout the document to make it clear, easy to read and professional looking

The key purpose of adding text to your presentation is to convince people that your town is a great place to live – be persuasive.  REMEMBER: your text needs to appeal to all of the family! 

  1. To add text to a slide, click into the text box and start typing
  2. To add a text box to a slide, click on the text box icon, click on the slide where you want the text box to be and start typing

You should not use more than two fonts in your presentation.  Add interest by using BOLD, ITALIC and UNDERLINE

  1. To add further effects to text, chose Format / Font.  

Do not get carried away adding text.  The GOLDEN RULE is no more than 5 lines of text with no more than 6 words per line – that’s 30 words – be concise. 

Recap:

Today we started to select and insert images;

say 3 things we learned (type this up in word) OR recap working in pairs as a critical friend.

Starter: Wordwall wordsearch – grab a handset and see how many words you can find.  You will need to type in each letter of the word to get the point.

Task 1

With the person next to you, can you remember the advantages of creating subroutines from a couple of lessons a go?

Task 2

Using the sheet called “creating subroutines” design two subroutines which will flash the lights on the big wheel in two separate sequences.  You can help each other but I would like everyone to complete the sheet.

Sequence 1 – All the lights flash once at the same time

Sequence 2 – The lights flash on and off by colour, one after the other.

Task 3

When you have designed your subroutines, you can test them by adding them to flowol and using the big wheel mimic.  To test your subroutines you will temporarily need to alter your flowchart so that it begins with a “start” rather than a “sub”.  When you know your subroutines work you can change them back to “sub” and call the first subroutine flash1 and the second one flash2.  Make sure you save your file.

Task 4

Can you work out how to create a main routine which runs your two flash subroutines continuously?  Tip – a process symbol might help.

Extension Activity

If you complete the subroutines and main routine, see if you can alter your main routine so that the lights only come on if input 1 (the first red button) is pressed.  Tip – you will need a decision symbol.

Starter: Wordwall – System Lifecycle

Task 1

In your wordwall groups, talk about the 6 analysis sections.  What are some of the important words you should use?  What should be in each section, what shouldn’t be?  How long should some of the sections be?

Feedback on Analysis of task 1

Task 2

In your same groups, I would like you to work on an example spreadsheet which will help the planning of school trips.  The spreadsheet is called School Trip Example and it can be found in Pupils:\Senior Pupils\ICT\GCSE\Coursework\Year 10\Task 2 – Spreadsheet

You only need to work on one version in your group but you might find it helpful if you all have it open so that you can experiment and explore.  Be ready for the “change!” instruction and let’s see who can complete the task first…

Task 3

Using your analysis template, please analyse this spreadsheet task.  The form of the output is simply “an onscreen spreadsheet model”

WEEK 4 – 22nd  September

8.1 Lesson 4 Environmental Tourist: Creating a Presentation. 

 

LEARNING OBJECTIVES

In today’s lesson you will learn how to;

  • Create a plan for a presentation that can be implemented by another person. 
  • Use the slide master to create a design template for a presentation. 

 

STARTER – Problems Encountered When Visiting a Website

Grab a white board, pen and cloth.  Work in pairs.  Jot down on your white boards at least three problems you have encountered when visiting a website. 

E.g. pages taking ages to download – usually because of image size, not having the right software to open files, pages look odd – usually a browser problem. 

 

Task 1 Planning the Content of Your Presentation. 

You are going to design a presentation for our new website.  The presentation should be a maximum of six slides, and you need it to include the following:

  • The name of the company
  • Our slogan, ‘The grass can be greener on a Go Green holiday!’
  • Our contact information:

The Go Green Travel Company, The High Street, Grimechester, Murkeyside, MY13 9ZX.

Tel. 0808 808080

URL: http://www.gogreentravel.co.uk

  • Information about how tourism is harming the environment. 
  • Information about how Go Green Holidays can help.
  • Up-to-date temperatures for some of our holiday destinations,
  • A page for our special offers, which change every six months.

The presentation should be aimed at young people between 13–18 years of age.  It needs to look fun and funky, and include images on at least four slides.  It also needs to include an automatically updated date and time in the footer of each slide.  It is going on the website and must be suitable for web use, so the file size must not be too big.

 

  1. Open the Presentation Planning worksheet (Reso4b). 
  2. Save this into your Unit 8.1 Environmental Tourist folder. 
  3. Add your NAME to the name dialogue box
  4. Call the worksheet Presentation Planning
  5. Use this sheet to plan the content of each slide in your presentation. Next to ‘Must have’, list the content that is essential.  Next to ‘Could have’, list things you would like to put on the slide, but don’t have to have.  In the long box at the bottom, note ideas about background, colours and fonts – and anything else you think would be good to include.

REMEMBER: This plan must be VERY clear to follow because you are going to give it to your partner to create the basic presentation. 

 

Task 2 Creating Your Basic Presentation. 

  1. SWAP computers and plans with your partner. 
  2. Open PowerPoint
  3. You have ten minutes to create a basic design by following your partners plan.  Concentrate on content, not design or style. 
  4. How easy was the plan to follow?  Write a short paragraph on your white boards to your partner explaining this. 

 

Task 3 The Slide Master. 

The slide master allows you to set styles, fonts and a background that will appear on every slide in your presentation. 

  1. To go to the slide master, choose View / Master / Slide Master
  2. To return to your presentation, choose View / Normal
  3. Decide what font, size, style and colour you want to use at each level.  Select each level to change individual styles or choose the font you want to use for all text in that box. 

If you place a place a background image on the slide master, the file size will be smaller.  This is important if you are going to use the presentation on the Internet. 

  1. Choose Insert / Picture / From File and find a suitable image, or Copy and Paste an image onto the slide.  Resize the image to fit. 
  2. Right-click on the picture and choose Order / Send to back to bring the master text boxes into view again. 

To add the date and time to each slide;

  1. Choose View / Header and Footer.  In the Date and time section, click on Update automatically, then choose the format you want from the drop down menu. 
  2. Click Apply to All.  The correct date and time will now appear at the bottom left-hand side of each slide. 

 

Task 4 Continue Designing Your Presentation. 

  1. SWAP back computers and plans with your partner. 

Continue designing your own presentation, using the slide master to set styles and background. 

  1. Choose File / Save As and save your presentation into your Unit 8.1 Environmental Tourist folder. 
  2. Call the presentation Go Green Holiday Presentation

 

TEST YOURSELF

Read the brief at the top of the page again.  Work in pairs.  On your white boards jot down whether or not your partner’s presentation has included all of the “must haves”.  Have they included any “could haves”? 

 

EXTENSION WORK

Open the Green Tourism Research work sheet (Reso4c). 

Save this into your Unit 8.1 Environmental Tourist folder. 

Add your NAME to the name dialogue box

Call the worksheet Green Tourism Research. 

Find out at least one fact about each of the issues listed, and one solution to help limit the problem.  You should also cite your source (where you found the information).

WEEK 4 – 22nd September

9.1 Lesson 4 Mayhem Manor: Main Routines – Sensors and Safety

 

LEARNING OBJECTIVES

In today’s lesson you will learn how to;

  • Understand the use of sensors in a system. 
  • Identify safety issues and possible ICT solutions. 
  • Create a program and add a safety feature. 

 

Starter – Automatic Door Flowchart. 

  1. Watch the presentation Sensors and Flowcharts (Reso4a) – slides 1 – 7. 
  2. Open the Automatic Door Flowchart (Reso4b).  Save this into your Unit 9.1 Mayhem Manor folder.  Add your name to the NAME dialogue box.  Work in pairs.  Arrange the flowchart symbols to build a working program to control an automatic door.  Add lines or arrows to show the order in which each instruction is carried out.  Then add loops to show how the system repeats, or goes back to check something.  You will need to add your own lines or arrows to do this.  REMEMBER: Your door must be safe, and not trap anyone in it! 
  3. Watch the presentation Sensors and Flowcharts (Reso4a) – slide 8. 
  • What is the problem with this solution? 
  • How could you change it?

(HINT: You must make sure that your program has a safety feature. 

  1. Watch the presentation Sensors and Flowcharts (Reso4a) – slide 9. 
  • Compare your solution to the one shown on slide 9. 

 

Task 1 Mind Map Safety Issues. 

Grab a white board, pen and cloth.  Work in pairs.  On your white boards sketch a mind map of safety issues relating to a big wheel.  Think about fairground rides you have been on to help you think of ideas.  Expand your mind map to include possible solutions to each problem. 

 

Task 2 Controlling the Movement of the Wheel. 

Open Flowol.  Open Big Wheel Mimic

  • Which elements of this mimic can be controlled
  • Which could be used to increase safety
  • What are these elements named

REMEMBER: an input puts something into the system – in this case it tells the wheel whether to move or not. 

HINT:  There are two components in the mimic that are essential for controlling the movement of the wheel, and one that is needed for safety

 

Task 3 Planning the Wheel Movement. 

Open the Wheel Movement Design Sheet (Reso4c).  Save this into your Unit 9.1 Mayhem Manor folder.  Add your name to the NAME dialogue box.  Work in pairs.  Write the instructions that will control the wheel.  REMEMBER: Input 2 is a switch that turns the ride on and that input 3 (gate) must be closed before the wheel will start turning (Mot A). 

 

Task 4 Create the Movement Program

Open Flowol.  Open your Lights ProgramCreate the new Movement Program on the same page, next to the lights program.  Don’t add the safety feature yet. 

 

Task 5 Adding a Safety Feature

You should now have a program that allows you to make the wheel turn by clicking on Input 2 on the Big Wheel Mimic (Input 1 controls the lights).  When you click Input 2 off, the wheel should stop turning. 

The gate is a safety element in the Big Wheel Mimic.  You need your program to tell the wheel to move ONLY if both Input 2 and Input 3 (the gate) are on.  If one of these components is switched off, the wheel should stop moving. 

To add the gate safety feature, you will need to insert a new symbol into the flowchart.  Click on the symbol you want to add on the left-hand toolbar, and then click on your flowchart in the place where you want to add the symbol.  Use the grey prompt box to program it.  

You will need to draw new lines to connect the symbols together.  To remove lines or boxes use the Edit tool, then click on the line or symbol you want to remove.  Finally, click on the Erase tool. 

There is more than one safe solution to include the gate input.

Task 6 Annotating your Flowcharts. 

To annotate programs, use the Add Label tool.  Annotate each process box and any loops to explain what each part of the program is doing. 

 

TEST YOURSELF

I am going to divide you into four or five teams.  Each team will have a copy off the quiz.  Answer the questions for ROUND 1.  Swap sheets with another team to mark your answers.  Swap back.  Answer the questions for ROUND 2.  Swap sheets with another team to mark your answers.  Swap back.  Answer the questions for ROUND 3.  Swap sheets with another team to mark your answers.  Swap back.  Answer the tie break question.  Swap sheets with another team to mark your answers.  Swap back

Starter – Automatic Door Flowchart. 

  1. Watch the presentation Sensors and Flowcharts (Reso4a) – slides 1 – 7. 
  2. Open the Automatic Door Flowchart (Reso4b).  Save this into your Unit 9.1 Mayhem Manor folder.  Add your name to the NAME dialogue box.  Work in pairs.  Arrange the flowchart symbols to build a working program to control an automatic door.  Add lines or arrows to show the order in which each instruction is carried out.  Then add loops to show how the system repeats, or goes back to check something.  You will need to add your own lines or arrows to do this.  REMEMBER: Your door must be safe, and not trap anyone in it! 
  3. Watch the presentation Sensors and Flowcharts (Reso4a) – slide 8. 
  • What is the problem with this solution? 
  • How could you change it?

(HINT: You must make sure that your program has a safety feature. 

  1. Watch the presentation Sensors and Flowcharts (Reso4a) – slide 9. 
  • Compare your solution to the one shown on slide 9. 

 

Task 1 Mind Map Safety Issues. 

Grab a white board, pen and cloth.  Work in pairs.  On your white boards sketch a mind map of safety issues relating to a big wheel.  Think about fairground rides you have been on to help you think of ideas.  Expand your mind map to include possible solutions to each problem. 

 

Task 2 Controlling the Movement of the Wheel. 

Open Flowol.  Open Big Wheel Mimic

  • Which elements of this mimic can be controlled
  • Which could be used to increase safety
  • What are these elements named

REMEMBER: an input puts something into the system – in this case it tells the wheel whether to move or not. 

HINT:  There are two components in the mimic that are essential for controlling the movement of the wheel, and one that is needed for safety

 

Task 3 Planning the Wheel Movement. 

Open the Wheel Movement Design Sheet (Reso3b).  Save this into your Unit 9.1 Mayhem Manor folder.  Add your name to the NAME dialogue box.  Work in pairs.  Write the instructions that will control the wheel.  REMEMBER: Input 2 is a switch that turns the ride on and that input 3 (gate) must be closed before the wheel will start turning (Mot A). 

 

Task 4 Create the Movement Program

Open Flowol.  Open your Lights ProgramCreate the new Movement Program on the same page, next to the lights program.  Don’t add the safety feature yet. 

 

Task 5 Adding a Safety Feature

You should now have a program that allows you to make the wheel turn by clicking on Input 2 on the Big Wheel Mimic (Input 1 controls the lights).  When you click Input 2 off, the wheel should stop turning. 

The gate is a safety element in the Big Wheel Mimic.  You need your program to tell the wheel to move ONLY if both Input 2 and Input 3 (the gate) are on.  If one of these components is switched off, the wheel should stop moving. 

To add the gate safety feature, you will need to insert a new symbol into the flowchart.  Click on the symbol you want to add on the left-hand toolbar, and then click on your flowchart in the place where you want to add the symbol.  Use the grey prompt box to program it.  

You will need to draw new lines to connect the symbols together.  To remove lines or boxes use the Edit tool, then click on the line or symbol you want to remove.  Finally, click on the Erase tool. 

There is more than one safe solution to include the gate input.

Task 6 Annotating your Flowcharts.

  1. Watch the presentation Sensors and Flowcharts (Reso4a) – slide 9. 
  • Compare your solution to the one shown on slide 9. 

 

Task 1 Mind Map Safety Issues. 

Grab a white board, pen and cloth.  Work in pairs.  On your white boards sketch a mind map of safety issues relating to a big wheel.  Think about fairground rides you have been on to help you think of ideas.  Expand your mind map to include possible solutions to each problem. 

 

Task 2 Controlling the Movement of the Wheel. 

Open Flowol.  Open Big Wheel Mimic

  • Which elements of this mimic can be controlled
  • Which could be used to increase safety
  • What are these elements named

REMEMBER: an input puts something into the system – in this case it tells the wheel whether to move or not. 

HINT:  There are two components in the mimic that are essential for controlling the movement of the wheel, and one that is needed for safety

 

Task 3 Planning the Wheel Movement. 

Open the Wheel Movement Design Sheet (Reso3b).  Save this into your Unit 9.1 Mayhem Manor folder.  Add your name to the NAME dialogue box.  Work in pairs.  Write the instructions that will control the wheel.  REMEMBER: Input 2 is a switch that turns the ride on and that input 3 (gate) must be closed before the wheel will start turning (Mot A). 

 

Task 4 Create the Movement Program

Open Flowol.  Open your Lights ProgramCreate the new Movement Program on the same page, next to the lights program.  Don’t add the safety feature yet. 

 

Task 5 Adding a Safety Feature

You should now have a program that allows you to make the wheel turn by clicking on Input 2 on the Big Wheel Mimic (Input 1 controls the lights).  When you click Input 2 off, the wheel should stop turning. 

The gate is a safety element in the Big Wheel Mimic.  You need your program to tell the wheel to move ONLY if both Input 2 and Input 3 (the gate) are on.  If one of these components is switched off, the wheel should stop moving. 

To add the gate safety feature, you will need to insert a new symbol into the flowchart.  Click on the symbol you want to add on the left-hand toolbar, and then click on your flowchart in the place where you want to add the symbol.  Use the grey prompt box to program it.  

You will need to draw new lines to connect the symbols together.  To remove lines or boxes use the Edit tool, then click on the line or symbol you want to remove.  Finally, click on the Erase tool. 

There is more than one safe solution to include the gate input.

Task 6 Annotating your Flowcharts. 

To annotate programs, use the Add Label tool.  Annotate each process box and any loops to explain what each part of the program is doing.
