Core Skills Analysis
Mathematics
Emily measured the lengths of each roller‑coaster track segment and recorded them in centimeters. She calculated the total length by adding the individual measurements and used fractions to determine the proportion of uphill versus downhill sections. By applying the concept of slope, Emily derived the gradient of each hill and compared them to decide which would provide the fastest ride. She also used simple ratios to scale her model from a 1 : 10 prototype to a full‑size design.
Science
Emily investigated how gravity and inertia affect a roller‑coaster car by observing how the model moved along the track. She noted the changes in speed at the peaks and valleys and linked these observations to potential and kinetic energy. By experimenting with different track angles, Emily discovered how steeper slopes increase acceleration, illustrating the principles of forces and motion. She recorded her findings in a science notebook, reinforcing the scientific method of hypothesis, testing, and conclusion.
Design and Technology
Emily sketched a blueprint for her roller‑coaster, selecting materials such as cardboard, straws, and tape to construct the structure. She evaluated each material’s strength and flexibility, then assembled the model according to her design plan. Throughout the build, Emily iterated on her prototype, making adjustments to improve stability and smoothness of the ride. She reflected on the design process, noting what worked well and what could be refined for a future version.
Tips
Encourage Emily to create a digital simulation of her roller‑coaster using free physics software to test different speeds and forces. Invite her to interview a local engineer or theme‑park designer for real‑world insight into safety standards. Organise a field trip to a science centre where she can experience real roller‑coasters and discuss the physics involved. Finally, have her write a short report comparing her model’s performance with that of a famous real‑world coaster, integrating research and persuasive writing.
