Sinusoidal Sleuths: Waves of the Future
1-pager
Purpose
Students will engage in a hands-on exploration of sinusoidal functions by modeling real-world phenomena such as sound waves, tides, and seasonal temperature changes. Through collaborative projects, students will apply mathematical principles to predict and analyze these phenomena, gaining insights into their applications in engineering, physics, and environmental science. The purpose of this project is to deepen students' understanding of how mathematical models can be used to interpret and solve real-world problems, fostering critical thinking and problem-solving skills.
Learning goals
Students will develop the ability to model real-world phenomena using sinusoidal functions, enhancing their understanding of periodic behavior in various contexts. They will apply mathematical concepts to predict outcomes and analyze the implications of these predictions in fields such as engineering, physics, and environmental science. Through collaborative projects, students will refine their problem-solving and critical thinking skills, while also improving their ability to communicate complex ideas effectively.
Standards
- Common Core - CCSS.MATH.CONTENT.HSF.TF.B.5: Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.
- Common Core - CCSS.MATH.CONTENT.HSF.IF.C.7.E: Graph trigonometric functions, showing period, midline, and amplitude.
- Common Core - CCSS.MATH.CONTENT.HSF.BF.A.1: Write a function that describes a relationship between two quantities.
Products
Students will collaboratively develop a digital presentation that models a real-world phenomenon using sinusoidal functions, such as ocean tides or sound waves. They will incorporate data analysis and graphical representations to predict future patterns and discuss implications in engineering, physics, or environmental science. Additionally, students will create a written report detailing their findings, methodologies, and the potential impact of their predictions on society, demonstrating their understanding and application of sinusoidal functions in real-world contexts.
Launch
Begin the project by taking students on a field trip to a local park or urban area where they can observe and record phenomena that exhibit sinusoidal patterns, such as tides, sound waves, or seasonal temperature changes. Encourage students to capture data through photos, videos, and measurements, which will serve as a foundation for their project work. Back in the classroom, facilitate a discussion on how these observations relate to sinusoidal functions and their applications in various fields, setting the stage for deeper exploration and modeling throughout the project.
Exhibition
Students will present their findings and models in a "Sinusoidal Functions Expo," where they showcase interactive displays that demonstrate real-world applications of sinusoidal functions. Each group will create a digital or physical model that predicts a specific phenomenon, such as tidal patterns or sound waves, and explain the implications of their predictions in fields like engineering or environmental science. Inviting local professionals and community members to the expo will provide students with an authentic audience, fostering meaningful dialogue and feedback on their work.
