Symmetry Project

As we have discussed during class, there are three types of symmetry: vertical line of reflectional symmetry, horizontal line of reflectional symmetry, and rotational symmetry.  For your first project, you will be creating a project on symmetry incorporating the following two parts. You will need to create an electronic document incorporating both part 1 and part 2.  Remember that all projects count as a test grade.  

Part 1:

 

The first portion must contain all 26 CAPITOL letters of the alphabet.  (worth 52 points, two points per letter)

 

·         You must organize these letters into four categories involving symmetry:  vertical, horizontal, rotational, and neither.  If the letter has rotational symmetry, label the degrees of rotation.  Some letters may appear in more than one category if that symmetry applies.

 

A  B  C  D  E  F  G  H  I  J  K  L  M  N  O  P  Q  R  S  T  U  V  W  X  Y  Z




Part 2: 

 

The second portion of the project must contain 10 different objects that you find in everyday life that are symmetrical.  Objects must be symmetrical!  Please copy and paste a picture of each of your 10 different objects into your document.    (worth 40 points, 4 points each item)

 

·         The items must be copied into your electronic  document. 

·         The items need to be numbered.

·         The items must be labeled. (What is your object?)

·         The items must be categorized according to its symmetry.

·         If your item has rotational symmetry, you must include the angle of rotation.

REMEMBER: ALL 10 OF YOUR ITEMS MUST BE SYMMETRICAL.  DO NOT USE ANY IN THE CATEGORY OF NONE!

*The last 8 points will be based on the presentation of your project.  Is your project neat and orderly?  Is your project easy to grade?  I will use the following rubric to grade your last 8 points.

 8         Project is neat, orderly without any mistakes.  Project is typed.  Exceptional thought and creativity             is displayed in project.

 

6         Project has one noticeable mistake, but the majority of the project is completed fairly well.

 

4         Project has 2 or 3 noticeable mistakes such as objects out of place or the project is not well organized.

 

2         Project has several noticeable mistakes and is completely unorganized.


I have included some examples to help you get started:

This image is an example of a rotationally symmetrical wheel that is used in everyday life.  By just looking at the hubcap without the valve and the very center, this object is rotationally symmetrical every 60 degrees because of the six spokes that go out.

Sans (without) the stem, this image is an example of a vertically symmetrical leaf that is in nature.

This image is an example of all three types of symmetry.  In addition to being vertically and horizontally symmetrical, this image is also rotationally symmetrical at 60 degrees.


Both part 1 and 2 must be present in your project.  To compile these two into one, you may create a poster or use presentation tools such as Microsoft Power Point or Prezi.  You may also create your project using tools such as Microsoft Word and Microsoft Publisher or apps such as Popplet.  If you choose to create your chart in a different technological tool than your final project, you can easily include this chart into your project simply by taking a screenshot and inserting it as an image into your presentation.
