Introduction





As evident from this video, there are many mysteries revolving the Great Pyramids. Generations have been fascinated by these pyramids and studied them immensely. Yet, there are still unanswered questions. Mathematicians are working to solve some of the mysteries using mathematics. You and your group will act as a researcher of the Great Pyramids and use mathematical analysis to solve some questions!


Modifications

This webquest had been modified from the original in many ways to better facilitate increased comprehension and task completion.

1. The tasks have been presented in much more detail, making it a step by step activity instead of an open ended one.
2. The websites have been updated to be more interactive and less wordy so that students are better able to identify the important information. Descriptions of the websites have been given as well.
3. A graphic organizer has been added to help visual students better understand how to accomplish this activity.
4. A list of vocabulary words has been provided to aid students in their understanding of the material.
5. A worksheet has been created that helps students stay organized in their research.
6. Examples and hints have been provided in the worksheet to guide students in their mathematical analysis.
7. The Webquest in general has been made more visual rather than text based. This was done by incorportating more images as well as video.

Websites

Use the following websites to help you in your research!

Measurements
National Geographic
Scroll over the pyramid images to see their names and click on the one you want to learn about. Measurements are provided in feet. This interactive website is also a good resource to learn about the history of each pyramid.
Pyramid Measurements
This website provides easy to find measurements of the Great Pyramid in terms of meters.

Formulas
World of Math
This link provides you with all the geometry formulas you will need for this assignment. Navigate the menu options to find your desired formula. For example, click "Volumes" to find the formula for the volume of a pyramid.

Construction of Scale Models
PBS Pyramids
This site provides you with information and examples about how to scale down a pyramid into model size. (Additional information can be found on your worksheet: Geometry Webquest Worksheet).

Interesting Facts
Pyramid Facts
Everything you want to know about the Great Pyramid can be found here in great detail. Much of the information is about the mystery of the pyramids and how advanced they are for their time.
PBS Explore

Vocabulary List

Area [air-ee-uh]
The quantitative measure of a plane or curved surface; two-dimensional extent.

Face [feys]
Geometry: any of the bounding surfaces of a solid figure: a cube has six faces.

Lateral Area [lat-er-uhexternal image thinsp.pngl air-ee-uh ]
The surface area of a 3D figure excluding the area of any bases.

Pyramid [pir-uh-mid]
Geometry: A solid having a polygonal base, and triangular sides that meet in a point.

Ratio [rey-shoh, -shee-oh]
The relation between two similar magnitudes with respect to the number of times the first contains the second.

Volume [vol-yoom]
The amount of space, measured in cubic units, that an object or substance occupies.


Illinois Learning Standards

This Webquest activity is intended for secondary geometry students. This project incorporates the use of technology by having students use the Internet to get resources and by having them present their findings using a computer program such as Powerpoint. In this Webquest they will work in teams and also develop communication skills by presenting their findings to the class.

In addition, this activity meets the following ISBE standards:

9.A.5 Use geometric figures and their properties to solve problems in the arts, the physical and life sciences and the building trades, with and without the use of technology.

Standard met when students solve for the area and volume in real world situations.

9.B.4 Recognize and apply relationships within and among geometric figures.

Comparing the two sizes of pyramids helps them recognize the relationships between them.

9.B.5 Construct and use two- and three-dimensional models of objects that have practical applications (e.g., blueprints, topo­graphical maps, scale models).

Standard used when students build the scale models of the pyramids.

9.D.4 Analyze and solve problems involving triangles using trigonometric ratios.

Such techniques must be used when solving for the lateral area of the pyramids.
