2. You will be assessed according to the attached rubric. Please ensure that you read it carefully and that you comply with the requirements therein.
4. Presentation of your project will be considered when marking.
5. Good luck and have fun!

### Task 1: History of measurement

Write a page (250 to 300 words) about the development of measures of length from ancient times through to the imperial system and the metric system.

Be sure to include a list of ALL of your references.

Your description must be written in your own words, so be careful not to (accidentally or on purpose) plagiarize any of your references. [12]

### Task 2: The five rand coin

For this part of the project, you will need to find yourself a new five rand coin.

1. Measure each of the following dimensions of the coin in millimeters (correct to 1 decimal place) and convert each of your answers to centimeters (correct to 2 decimal places):
1. the diameter of the whole coin, D (2)
2. the diameter of the inner gold circle, d (2)
3. the height or thickness, h (2)
2. Now calculate each of the following, carefully showing all your working:
1. the total surface area of the coin (in cm2). Hint: remember to include the top of the coin, the bottom of the coin AND the sides of the coin. (4)
2. the total volume of the coin (in cm3). (3)
3. the volume of the inner gold disk (in cm3). (3)
4. the volume of the silver ring (in cm3). (2) [18]

### Task 3: Building a random object

For the last task of this project, you need to do three things:

1. Using the net supplied, build the three dimensional object shown below by folding it carefully along the fold lines and gluing it together on the glue flaps. (8)

| A lens I own (?)

#### Definition of a lens

##### Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

##### What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

##### Who can create a lens?

Any individual member, a community, or a respected organization.

##### What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
