Core Skills Analysis
Science
Ani‑Maree examined how light travels in straight lines, observed that it does not bend, and identified its incredible speed of approximately 300,000 km per second. She explained that light enables vision by entering the eyes and being focused on the retina, and she listed natural and artificial light sources such as the sun, lamps, and LEDs. By investigating the light spectrum, she recognized that white light separates into the familiar colours of the rainbow when passed through a prism. Finally, she described how the eye’s cornea and lens reflect and refract light to create the images we see.
Mathematics
While studying light’s speed, Ani‑Maree used the value 300,000 km s⁻¹ to compare distances travelled in a fraction of a second, converting kilometres to metres and calculating how far light moves in one nanosecond. She applied measurement concepts to estimate how many school‑yard lengths light could cover in a blink of an eye. By representing the speed as a ratio, she practiced writing and simplifying fractions and decimal equivalents. These calculations reinforced her understanding of unit conversion and proportional reasoning.
Tips
Tips: Conduct a classroom experiment using a laser pointer and a sheet of white paper to trace straight‑line paths and discuss why light does not bend in air. Create a speed‑of‑light relay where students calculate how far light travels in various time intervals, reinforcing measurement and estimation skills. Use a prism or a CD to split white light and have learners record the colour spectrum in a scientific sketch journal, integrating observation and labeling. Finally, design a simple model of the eye using cardboard and lenses to demonstrate how reflection and refraction produce vision.
