From Tetrahedral Concept to Creation Building Science & Technology 6th 8thGrade
Overview: An architect has asked you to design a building using tetrahedral structures. Students will demonstrate their understanding of tetrahedrons and the strength they provide to structures.

Problem Guide Timeframe This lesson plan will take approximately five weeks. Have each team begin a list of POSSIBLE HYPOTHESES [page 12]. Step-by-step guide Allow teams to research and explore the LEARNING ISSUES [pages 9 & 13]. Put students into teams of three to five members. Teams reevaluate their POSSIBLE HYPOTHESES [page 12] and determine one DEFENDABLE SOLUTION for the Final Product [page 14]. Ask for a volunteer to read the STUDENT PROBLEM aloud [page 6]. As a whole group, ask students to list What We Know [KEY FACTS, page 7]. Teams create and present their DEFENDABLE SOLUTION [page 14]. Have each team create a list of What We Need to Know [NEED TO KNOWS & LEARNING ISSUES, pages 8 and 9].

Student Problem For your science fair project this year, you have chosen to display tetrahedral structures in a variety of ways to demonstrate their cohesiveness and strength. Triangles are generally considered the strongest shape, making the tetrahedron a strong structural element in everything from atomic bonding to electrical components. An architect sees your project and finds it interesting. She asks that you design a building using the same structure combinations you have used in your project and explain the concept of tetrahedral strength in a presentation to her firm. Consider: What is a tetrahedral structure? How can you combine tetrahedrons to create a building?
Key Facts You have chosen to display tetrahedral structures at this year s science fair. Your science fair project demonstrates the strength and cohesiveness of tetrahedral structures. Triangles are considered a strong shape. The tetrahedron is a strong structural element in everything from atomic bonding to electrical components. An architect finds your project interesting. The architect has asked you to design a building using tetrahedral structures. The architect would like you to explain the concept of tetrahedral strength in a presentation to her firm.
Need to Knows Need to Knows Need to Know Answers What tetrahedral structure combinations did we use in our science fair project? How tall does the building need to be? How will we present our design? Facilitator may provide teams with common tetrahedral structural combinations or allow them to research the combinations on their own. Facilitator may choose dimensions based on the ability level of the students. Facilitator may decide how students will present their final product to the firm, with a focus on the drawing and building of a prototype.
Learning Issues Learning Issues Learning Issue Resources What is a tetrahedron? Where does the strength of a tetrahedron come from? How do tetrahedral shapes fit together? Is the tetrahedron only functional or does it have aesthetic value as well? How can you combine tetrahedrons to create a building structure? Students will investigate using the Learning Issue Resource Guide, page 13.
Additional Information Students should individually generate at least one possible hypothesis to bring to their team. As a team, students will define their problem statement and generate multiple hypotheses for possible solutions. Teams can demonstrate their understanding of the strength of tetrahedrons by designing and drawing a prototype of a building structure. The facilitator may decide what materials and technology may be used to test possible solutions. Teams should reevaluate their possible hypotheses after testing possible solutions and choose one to create their presentation.
Interdisciplinary Connections Math: Art: Geometry Solving real-world problems Science: Investigation and evaluation English: Research practices Presentation practices Social Studies: City development Complementary function and design Social/Emotional: How to work in teams and problem solving
Hypotheses Hypotheses will vary by each team s design of the building using tetrahedral structures. Hypotheses will vary by each team s reasoning behind the tetrahedral structures chosen in the building s design.
