Curiosities and Market Connection

 Curiosities and Market Connection:

Understanding the volume of prisms is essential in the construction industry to ascertain the quantities of materials, such as concrete and steel, needed for projects. Architects rely on these calculations to effectively design spaces, ensuring that the volumes of various areas support both functionality and aesthetics. In packaging, knowing prism volumes helps optimise transport and storage solutions, directly affecting costs and efficiency.

Contextualization

Spatial geometry is a cornerstone of mathematics with clear applications in our everyday lives. Knowing how to calculate the volume of prisms is vital for many careers, from civil engineers working out the amount of concrete for a build to product designers managing packaging. Thus, mastering this skill is both practical and invaluable.

Initial Activity

 Initial Activity:

Provocative Question: Pose the question to the students, 'Did you know that calculating the volume of a prism could impact the costs of a construction project or the design of a product? How do you think that works?' Short Video: Show a brief video (2-3 minutes) illustrating how architects and engineers apply volume calculations in practical settings. Suggested video: 'How Engineers Use Maths in Real Life' available on YouTube.

Development

Duration: 60 to 70 minutes

This segment aims to let students practice theoretical concepts in hands-on and interactive ways. By constructing and computing prism volumes, they build relevant skills and problem-solving abilities applicable in fields like engineering, architecture, and design. Additionally, the exercises reinforce learning and help assess understanding.

Topics

1. Definition of prisms

2. Calculating the base area of various prisms

3. Understanding the relationship between base area and height for volume calculation

4. Practical uses of volume calculations across professions

Thoughts on the Subject

Encourage students to meditate on how spatial geometry, particularly the calculation of prism volumes, is applied in different professions. Prompt them to consider how engineers, architects, and designers might use these calculations in their everyday tasks. Suggest specific examples, such as building projects, furniture design, or product packaging.

Mini Challenge

Build a Prism

Students will create a prism using everyday materials and compute its volume.

1. Split the class into small groups of 3-4 students.

2. Provide each group with supplies like cardboard, rulers, scissors, tape, and graph paper.

3. Each group chooses a prism type (triangular, rectangular, hexagonal, etc.) and sketches its base on graph paper.

4. After drawing, students cut out and assemble the prism with cardboard and tape.

5. Upon completion, each group measures the height and calculates the base area using their graph paper.

6. Finally, students compute the volume using the formula Volume = Base Area x Height.

7. Each group shall present their prism along with an explanation of their construction and volume computation.

Foster practical skills in building and measuring while applying the concept of prism volume through a hands-on project.

**Duration: 30 to 40 minutes

Evaluation Exercises

1. Calculate the volume of a rectangular prism with base dimensions of 5 cm x 3 cm and a height of 10 cm.

2. A triangular prism has sides measuring 6 cm, 8 cm, and 10 cm at a height of 12 cm. Find its volume.

3. Determine the volume of a regular hexagonal prism with an apothem of 5 cm, sides of 6 cm, and a height of 15 cm.

4. Draw a pentagonal prism and calculate its volume, detailing all measurements used.
