Elliptical Orbits Project (PBL) - Precalculus Conic Sections & Eccentricity
This engaging Project-Based Learning (PBL) activity brings conic sections to life by having students explore how ellipses model real-world orbits. Students select a planet, moon, comet, or satellite and use research to gather key data such as eccentricity and orbital measurements, then create a mathematical model using the equation of an ellipse. They will construct and label a diagram, analyze how eccentricity affects the shape of the orbit, and present their findings through a visual project.

Binomial Theorem Christmas Tree | Pascal’s Triangle Holiday Math Activity
Make practicing the Binomial Theorem more engaging with this Christmas tree project! Students begin with a pattern-discovery lesson using Pascal’s Triangle and binomial expansions, then apply what they learn by expanding an assigned binomial from the 1st through 5th powers.After completing their expansions independently, students find classmates with the same assigned binomial, compare answers, and work together to create a festive Christmas tree display. Each term of each expansion is written o
