Name Date
Circle the best answer.
1. Which is more reliable over a long distance at night?
A. A whispered pattern B. A pattern of bright flashes C. A pattern of small taps 2. Long and short flashes stand for letters. What makes that a code?
A. The brightness B. An agreed pattern that stands for information C. The colour of the torch 3. Why is a pattern better than a single signal for sending words?
A. Different patterns can stand for different things B. Single signals are illegal C. Patterns are prettier 4. A message arrives with one flash missing. What can happen?
A. The pattern is misread, so the information is wrong B. The message gets shorter C. Nothing changes 5. Why must both people know the code before it is used?
A. Otherwise the pattern carries no meaning to the receiver B. To be polite C. To save the battery 6. Which of these transfers information by a pattern?
A. A drum left silent B. A drum beaten in a rhythm that means 'come here' C. A drum beaten at random 7. Why do some codes repeat each message twice?
A. To fill time B. So a missed part can be caught the second time C. To use more battery 8. Two designs send the same message. How would you compare them?
A. Measure which is heavier B. Count how often the message arrives correctly C. Ask which looks better LessonPrint · 4-PS4-3 · Set 11 · free to copy for classroom use
