Two Helper Tables
At a city park, Inez and Omar help with a maze game. Their tables are 20 big steps apart. A tall hedge stands between them. They cannot see each other's table, but they can hear a hand drum. They need to send two messages without leaving their tables.
They can make a drum from an empty container with a lid. They will tap the lid gently with a hand. One tap will mean “come.” Two quick taps will mean “wait.” They will leave a long pause between messages. They also have a flashlight and cardboard for making a holder.
1.
Which plan best fits the tables behind the hedge?
○A.Hold up a card for Omar to read.
○B.Flash a light low behind the hedge.
○C.Tap a drum for Omar to hear.
○D.Wave a flag below the hedge.
2.
Which parts can make the drum described in the passage?
○A.A flashlight and a cardboard holder
○B.An empty container and its lid
○C.A paper flag and a short stick
○D.A message card and a card stand
3.

○A.Two quick taps, long pause, one tap
○B.One tap, long pause, two quick taps
○C.Two quick taps, long pause, two quick taps
○D.One tap, long pause, one tap
4.
How can Inez check that Omar understood a test message?
○A.Check whether her drum has a lid.
○B.Count how many taps she can make.
○C.Look at the color of Omar's table.
○D.Ask Omar which message he heard.
Compare the Drum Tests
Use the test notes and graph. A correct message means Omar heard the taps and named the right message.
The helpers test three drums: a cup, a box, and a tub, each with a lid. They stay at the same tables. Inez sends the same five messages with each drum. She uses gentle hand taps each time. Omar records how many messages he names correctly.
5.
How many more messages were correct with the tub than with the cup? more messages
6.
The helpers want at least four correct messages in five tries. Which drum met that goal?
○A.The cup drum
○B.The box drum
○C.All three drums
○D.The tub drum
7.
Circle the TWO claims the graph supports.
The box worked better than the cup in this test.The cup and tub worked equally well in this test.The box worked better than the tub in this test.The tub worked better than both other drums in this test.
8.
For a new test, Omar moves close for the cup but far away for the tub. What should the helpers fix?
○A.Use a different message code for each drum.
○B.Use the same distance for both drums.
○C.Send more messages with only the tub.
○D.Use gentle taps for only the cup.
Design for a New Spot
Use the new clues. Then draw a device and tell how to test it.
Later, the helpers move to two tables beside a clear path. No hedge blocks the view. Nearby music covers the drum taps, but Omar can see Inez's flashlight flashes. They agree that one flash means “come” and two quick flashes mean “wait.” For safety, they aim the light at a card beside Omar, never at his eyes.
9.
Which device best fits the new spot?
○A.The cup drum tapped under a thick cloth
○B.The tub drum tapped behind a large box
○C.A flashlight in a holder aimed at the card
○D.A flashlight in a holder aimed at the ground
10.
The cardboard holder tips over during a test. Omar misses the flashes. What should Inez try next?
○A.Add a wider base and test the holder again.
○B.Use the same holder and change the flash code.
○C.Keep the tipped holder and flash more quickly.
○D.Leave the holder tipped and move Omar farther away.
11.
Draw your light device for the clear path. Show the flashlight, a holder that will stand up, and the card where the light will shine.
