Science
Danae referred to the Periodic Table on pages 3‑4 and created one orange card for each of the six halogen elements. She wrote the chemical symbol on one side of each card and the full element name on the reverse, then practiced flipping the cards to recall each symbol. Through this activity she demonstrated that she could accurately identify and name all halogen symbols, reinforcing her understanding of element classification, periodic trends, and the purpose of chemical symbols.
Tips
Tips: 1) Turn the cards into a timed matching game with a partner to boost recall speed. 2) Research one real‑world use for each halogen (e.g., disinfectants, lighting, pharmaceuticals) and create a short presentation. 3) Conduct a safe, supervised demonstration of a halogen reaction, such as observing chlorine water’s colour change, to link symbols with observable properties. 4) Extend the set by adding the noble gases and compare their reactivity with the halogens.
