Patterns That Carry a Message 4-PS4-3
Name Date
Circle the best answer.
1. Why do some codes repeat each message twice?
A. So a missed part can be caught the second time B. To use more battery C. To fill time 2. Two designs send the same message. How would you compare them?
A. Measure which is heavier B. Ask which looks better C. Count how often the message arrives correctly 3. Long and short flashes stand for letters. What makes that a code?
A. An agreed pattern that stands for information B. The colour of the torch C. The brightness 4. A message arrives with one flash missing. What can happen?
A. The message gets shorter B. Nothing changes C. The pattern is misread, so the information is wrong 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. Which of these transfers information by a pattern?
A. A drum beaten in a rhythm that means 'come here' B. A drum left silent C. A drum beaten at random 7. Why is a pattern better than a single signal for sending words?
A. Patterns are prettier B. Single signals are illegal C. Different patterns can stand for different things 8. Why must both people know the code before it is used?
A. Otherwise the pattern carries no meaning to the receiver B. To save the battery C. To be polite LessonPrint · 4-PS4-3 · Set 19 · free to copy for classroom use
