Trignometry beyond the Classroom in Year 8
Real life applications of Trignometry
In Term 1, Year 8 students applied their trigonometry skills to calculate the heights of various structures around the school. After learning about angles of elevation and depression, they used tools like trundle wheels to measure distances and clinometers to find angles of elevation. Their goal was to solve real-world problems using the sine, cosine and tangent ratios they had been studying in class.
One of the highlights was measuring the height of the school’s flagpole, which was calculated to be 15 metres. Students also applied the same method to the Sala, measuring it at roughly 8 metres, and explored other buildings such as the art block. Additionally, they took their skills indoors and measured the height of the DNA structure in the science department, showcasing the versatility of trigonometry in different environments.
This hands-on project allowed students to see how architects and engineers use trigonometry in everyday life. Whether it’s measuring buildings, analysing architectural designs, or understanding scientific models, Year 8 students now appreciate the practical value of trigonometry and how it can be applied beyond the classroom.
