Contextualization
Cartesian Geometry, a branch of mathematics named after the philosopher and mathematician René Descartes, is an exciting concept that forms the basis of much of modern mathematics and physics. It describes the fundamental relationship between algebraic equations and geometric shapes, allowing us to understand and manipulate these shapes using the language of numbers and symbols.
One of the most powerful tools in Cartesian Geometry is the equation of conics. Conics are a group of curves formed by intersecting a plane and a right circular cone. They include circles, ellipses, parabolas, and hyperbolas, each with its unique equation. The equation of these conics allows us to describe their shape, position, and orientation in a simple, elegant form.
Conics have a wide range of applications in real-world scenarios. They are used in physics to describe the path of a projectile, in astronomy to model the orbits of planets, and in engineering to design objects with specific shapes and properties. Understanding the equation of conics can provide a powerful tool for solving real-world problems in these and many other fields.

Practical Activity
Activity Title
"The Conic Carnival: Exploring the Equation of Conics"
Objective of the Project
The main objective of this project is to enable students to understand and practically apply the theoretical knowledge they have gained about the equation of conics. The project will require the students to create and present a "Conic Carnival" – a carnival-themed display showcasing the four types of conics: circle, ellipse, parabola, and hyperbola.
Detailed Description
Each student group will be tasked with creating a carnival booth for each type of conic section. The booth should contain a large, visually appealing display that clearly shows the equation of the respective conic section, its properties (such as vertices, foci, and directrix), and real-world examples of where the conic section occurs.
For example, the booth for a circle should have a large circular object (like a Ferris wheel) with the equation of a circle inscribed on it, along with illustrations of real-world applications of circles like wheels, plates, etc. The booth for an ellipse could have an egg-shaped ride, with its equation and examples of where ellipses are used (like in sports arenas).
The purpose of this project is to help students understand how these abstract mathematical concepts apply to real-world objects and events. The students will have to research and understand the properties and equations of each conic section and find real-world examples to illustrate them.
Necessary Materials
- Poster boards or cardboard for creating the booths
- Markers, colored pencils, and other art supplies for decorating the booths
- Internet access for research
- Reference books or approved online resources for studying the topic
- Access to a presentation space for the final carnival display
Detailed Step-by-Step for Carrying Out the Activity
Step 1: Forming Groups and Assigning Roles
Form groups of 3 to 5 students. Each group should assign roles to its members, such as researcher, designer, artist, presenter, etc. Each role will have specific responsibilities throughout the project.
Step 2: Research and Development
Each group will research about the four types of conic sections: circle, ellipse, parabola, and hyperbola. They should understand and note down the general form of the equation for each conic section, as well as important properties like the foci, directrix, vertices, and real-world examples.
Step 3: Sketching and Planning
Based on their research, each group should sketch out their carnival booths, deciding how they will represent the conic sections and their properties. They should also plan how they will display the equation of each conic section and its real-world examples.
Step 4: Creating the Carnival Booths
Using the materials provided, each group will create their carnival booths. They should ensure that the equations are correctly represented, and the real-world examples are clearly illustrated.
Step 5: Final Review and Edits
Once the booths are complete, each group should review their work to ensure accuracy and clarity. They should make any necessary edits or additions.
Step 6: Presentation
The final step is for each group to present their carnival booth to the class. They should explain the equation and properties of each conic section, as well as their real-world examples. They should also be prepared to answer questions from their classmates and the teacher.
Project Deliverables
The main deliverable of this project will be the completed carnival booths and the final presentation. However, each group is also required to submit a written report detailing their project.
The report should contain the following sections:
-
Introduction: In this section, students should briefly explain the concept of the equation of conics, its relevance, and real-world applications. They should also describe the objective of the project.
-
Development: Here, students should detail the theory behind the equation of conics, explaining each type of conic section and its equation. They should then detail the steps they took to complete the project, including their research process, the planning and creation of the carnival booths, and the final presentation.
-
Conclusions: In this section, students should discuss what they learned from the project, both in terms of the mathematical concepts and the skills they developed. They should also reflect on any challenges they encountered and how they overcame them.
-
Bibliography: Finally, students should list the resources they used during their research. This can include textbooks, online articles, videos, etc.
The report should be detailed, well-organized, and well-written. It should clearly demonstrate the students' understanding of the equation of conics, their ability to apply this knowledge to real-world examples, and their collaboration and communication skills.
