Cambridge Secondary (7-9). Stage 8. MCE Science. Workbook - Unit 13: Weather and Climate - Question 4

Build a rain gauge using a plastic bottle, short transparent plastic ruler, sticky tape and, optionally, rocks and stones. Ask an adult to help cut the top two-thirds off the bottle with a craft knife or scissors. Tape the ruler outside so the water level is visible against its scale, on a part where the bottle diameter does not change. Place it outside where it can catch rainfall and stabilise it if necessary. Fill it with water to the ruler’s 0 mark. Empty it every day and add water again to the 0 mark.



How could you improve your rain gauge? For each suggestion, explain why it would improve your rain gauge.
