Subject: Mathematics (9 - 12), or Technology Education (9 - 12)
Title: The Geometry Around Us
Description: This is an introduction to geometry with a technology-based project in which students will go out looking for geometric shapes in the world around them.  Students will capture pictures or video of the objects they find using a digital camera/camcorder and put all of them together into a multimedia presentation.  The students will then upload their projects to edmodo.com.

Title: Let's Go Hunting!
Description: Students will work in groups of 3 or 4 scouring the campus for items of various shapes, sizes and angles. The items that students will be looking for are outlined on the rubric. Students will use technology to create a creative digital presentation representing all of their captured scenes. Students will work in class to create this presentation and then be prepared to present it on the assigned viewing date.

Title: Minerals
Description: The students will gain information on the 5 characteristics of minerals. The information can be related to nonrenewable resources. This lesson should facilitate discussion on the difference in precious gems and semi-precious gems.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Title: Water Tank Creations Part I
Description: In this lesson students will study the surface area and volume of three-dimensional shapes by creating a water tank comprised of these shapes. Students will work in groups of 4-5 to research water tanks, develop scale drawings and build a scale model. Teacher will evaluate the project using a rubric and students will assess one anothers cooperative skills using a rubric.

Title: Creating a Water Tank - Part II "Selling the Tank"
Description: Working in groups of 4-5 students will take the information,pictures and 3-D model of the water tank they assembled in Part I of Creating a Water Tank and develop a web page and a video presentation. The web page will be a tool to advertise their water tank construction company and must include hyperlinks and digital pictures. The video presentation will be a "sales pitch" to a city council. The web page and video will be scored using a rubric. The web page and video must include the surface area, volume and cost of construction.

Title: Building Height
Description: In this Illuminations lesson, students use a clinometer (a measuring device built from a protractor) and isosceles right triangles to find the height of a building. The class compares measurements, talks about the variation in their results, and selects the best measure of central tendency to report the most accurate height.

Title: Circle Packing
Description: In this unit of three Illuminations lessons, students explore circles. In the first lesson students apply the concepts of area and circumference to explore arrangements for soda cans that lead to a more efficient package. In the second lesson they then experiment with three-dimensional arrangements to discover the effect of gravity on the arrangement of soda cans. The final lesson allows students to examine the more advanced mathematical concept of curvature. There are also links to online interactives that are used in the lessons.

Subject: Mathematics
Title: Soda Rack
Description: In this lesson, one of a three-part unit from Illuminations, students consider the arrangement of cans placed in a bin with two vertical sides and discover an interesting result. They then prove their conjectures about the interesting results. In addition, there are links to online activity sheets and other related resources.
