Graphics are computer images displayed on a monitor. 'Graphic' means 'an image created by drawing or painting'. Computer graphics are images displayed on a computer screen. Although a screen is two-dimensional (2D), special software can help in creating 3D graphics such as you would see in a video game. Graphics programs can help us to edit photographs, illustrate text documents, make graphs and charts, or create works of art, as well as play games.

1. Which of these tools would you find in a paint package (computer program)?
[ ] Pencil sharpener
[ ] Rubber / eraser
[ ] Compass
[ ] Screwdriver

[ ] A plan for a new playground
[ ] A newspaper article
[ ] A poster
[ ] A database
3. What does it mean to 'rotate' an object or image?
[ ] The object is flipped so that it is displayed as a mirror image
[ ] The object is cut and pasted
[ ] The object is saved
[ ] The center of the object stays in the same place while the object is turned
4. What does the 'crop' tool do?
[ ] It allows you to change the color of an image
[ ] It deletes a photo or image
[ ] It allows you to select and use part of an image
[ ] It allows you to harvest your work

[ ] 'Ungroup' and select the object you wish to edit
[ ] Send the object behind the other shapes
[ ] Crop the shapes you wish to keep
[ ] None of the above
7. When you add graphics to a word processing document, some images appear to go behind other images. What can you do to control this?

Computer Science: Middle School: Grades 6, 7 and 8 Quiz - Graphics (Answers)
1. Which of these tools would you find in a paint package (computer program)?
[ ] Pencil sharpener
[x] Rubber / eraser
[ ] Compass
[ ] Screwdriver
You use the eraser just as you would in real life, to erase your mistakes
2. Using a software package to create a 2D visual model of something you might create in 3D is called graphical modeling. Graphical modeling would be used for which of the following?
[x] A plan for a new playground
[ ] A newspaper article
[ ] A poster
[ ] A database
The plan is a two-dimensional (2D) visual image of the new playground, which will, of course, be three-dimensional (3D) - modeling allows objects to be moved around much more easily in 2D than they would be in real life
3. What does it mean to 'rotate' an object or image?
[ ] The object is flipped so that it is displayed as a mirror image
[ ] The object is cut and pasted
[ ] The object is saved
[x] The center of the object stays in the same place while the object is turned
You can rotate an image clockwise or counterclockwise
4. What does the 'crop' tool do?
[ ] It allows you to change the color of an image
[ ] It deletes a photo or image
[x] It allows you to select and use part of an image
[ ] It allows you to harvest your work
This is useful if you want to make a picture a certain size or shape
5. When using a word processing package, you can change a shape by adding which of these?
[ ] Colour
[ ] A thicker outline
[ ] A 'shadow'
[x] All of the above
These are all options available to you
6. You have 'grouped' several shapes in order to make the image of a train. If you change your mind and want to edit just one of the objects, what can you do?
[x] 'Ungroup' and select the object you wish to edit
[ ] Send the object behind the other shapes
[ ] Crop the shapes you wish to keep
[ ] None of the above
'Grouping' objects is helpful when you want several objects to behave as one object
7. When you add graphics to a word processing document, some images appear to go behind other images. What can you do to control this?
[ ] Copy and paste
[ ] Delete
[x] Select 'text wrapping' from the drawing tools and choose the correct effect
[ ] Give up
In some word processing programs, you can also choose to send objects behind or in front of other objects
8. What does it mean to 'draw' using a software program?
[ ] Typing the word 'draw' into a word file
[ ] Naming your file 'Draw'
[ ] Inserting a photo or clip art into a document
[x] Using various tools to create objects, such as shapes
An object which has been drawn can be edited, deleted, copied or moved like any other inserted objects
9. Photos can be edited by changing what?
[ ] Contrast
[ ] Brightness
[ ] Color saturation
[x] All of the above
There are many ways you can edit your photos
10. A 'fill' tool can fill a shape with what?
[ ] With color only
[x] With color, texture, patterns or pictures
[ ] With texture and color only
[ ] None of the above
Computers make tasks a lot easier - imagine having to color all the shapes in by hand, it would take much longer
