Circle the best answer.
1. Which of these transfers information by a pattern?
A. A drum beaten in a rhythm that means 'come here' B. A drum beaten at random C. A drum left silent 2. Why is a pattern better than a single signal for sending words?
A. Single signals are illegal B. Different patterns can stand for different things C. Patterns are prettier 3. A message arrives with one flash missing. What can happen?
A. Nothing changes B. The pattern is misread, so the information is wrong C. The message gets shorter 4. Why do some codes repeat each message twice?
A. To use more battery B. To fill time C. So a missed part can be caught the second time 5. Which is more reliable over a long distance at night?
A. A pattern of small taps B. A pattern of bright flashes C. A whispered pattern 6. Why must both people know the code before it is used?
A. To be polite B. Otherwise the pattern carries no meaning to the receiver C. To save the battery 7. Two designs send the same message. How would you compare them?
A. Ask which looks better B. Count how often the message arrives correctly C. Measure which is heavier 8. Long and short flashes stand for letters. What makes that a code?
A. The colour of the torch B. An agreed pattern that stands for information C. The brightness LessonPrint · 4-PS4-3 · Set 9 · free to copy for classroom use
