Entry Events

Events that will be used to introduce the project to students

The Mystery of the Collapsing Bridge

A local bridge, designed using polynomial equations, has shown signs of instability. Engineers present photos/videos and data, challenging students to discover the error in the polynomial calculations that led to the design flaw, connecting polynomial functions to real-world structural integrity and safety.

The Case of the Miscalculated Medication

A pharmacist has made an error in calculating drug dosage based on a polynomial model of drug absorption rates. Students receive patient data and the original polynomial equation. Their task is to identify the error, recalculate the correct dosage, and explain the potential consequences of the mistake, linking polynomials to real-world health and ethical considerations.

Economic Model Crisis

The city's economic forecast, modeled by polynomial functions, predicts a sudden downturn. Students are presented with the model and real economic data. They must analyze the polynomial, identify potential flaws or limitations in the model, and propose alternative or adjusted polynomial models that better reflect economic trends and predict future outcomes.

The Perfect Garden Design

A local community garden wants to optimize the planting area using polynomial functions to maximize space and yield. Students will explore how manipulating polynomial equations impacts area and volume, then design a garden layout using specific polynomial constraints, presenting their design to a 'garden committee' for approval based on yield, aesthetics, and accessibility.
