- During design review time, Sofia and Chen tested two containers to organize supplies. Design A was one big box, and the items got mixed up (yes). Design B had dividers, and the items stayed separated (yes). Both designs tried to solve the same organization problem. Design B's strength is dividers keep things apart, and Design A's weakness is items mix together. Chen pointed to the results and said, "Separated helps us find things fast." Sofia said, "Let's choose using evidence, not guessing." Their teacher asked, "Which design should we choose and why?" Based on the test results, which container design should they choose and why?
- Yuki watched the moon at bedtime for 4 nights. What did she notice?
- Carlos saw the moon outside one window, then another window. What pattern is shown?
- A fish lives underwater. What would happen without its gills?
- Sofia watched the sun 4 days: morning low, noon high, evening low. What pattern do the observations show?
- Read Jamal's classroom notes. Objects: desk, chair, board, bookshelf. At 7am (dark) he wrote "invisible - too dark" for all. At 8am (bright) he wrote "visible - light present" for all. What evidence did Jamal collect?
- Yuki and Carlos test two shelves for book storage. Design A (one shelf) held 8 books. Design B (three shelves) held 24 books. They use the data to name strengths and weaknesses. Based on the data, what is a strength of Design B?
- Maya eats soup and salad. How do bird beaks solve problems like this?
- Carlos looked at the sun for three days. Each day: morning low, noon high, evening low. Which statement is true about this pattern?
- Read about Emma upstairs with her door closed. How could light or sound help solve this problem?
- Keisha and Chen tested bases to keep a block statue standing. Design A has a narrow base and it tipped (yes). Design B has a wide base and it stayed up (yes). A tried to stand, but tipping was a weakness. B was strong because it stayed stable. They must pick the base that solves the tipping problem. Design B works better than Design A because the data shows it stayed up. The wide base keeps it from tipping, so it stands safely. Using the test results, which design should they choose and why?
- Maya looked at the stars: Mon night yes; Tue night yes; Wed day no; Thu night yes. What is true about this pattern?
- An elephant needs water. How does its trunk help it drink?
- Look at Jamal's dinner bell. What does 3 rings mean?
- After recess, Carlos and Keisha line up to get a drink. They notice the water fountain button is high. Carlos stretches and still cannot press it. Keisha asks three kids and two say, "I can't reach." They watch and see some kids jump to reach the button. The teacher says, "State the problem clearly." They define: "The problem is some kids can't reach the water fountain button." A new tool could help kids reach safely. Based on the information, what problem did they define?
- Maya says, "You cannot see things in the dark." Her tests: 1) Toy car in dark room—could NOT see it. 2) Toy car with flashlight—COULD see it. 3) Toy car in daylight—COULD see it. Does Maya's test prove her claim?
- At the art center, Maya's markers keep rolling off the table. She shows a marker holder with many round holes on top. The holes are the same size as the marker caps. Maya points and says, "The round holes hold the markers in place." She adds, "They fit snug, so the markers don't roll away." Maya says, "That helps so we don't lose markers on the floor." She puts a marker in and gently bumps the holder. Her friend says, "Oh, they stay standing up!" What does Maya's explanation show about the round holes?
- Read how Carlos improved his whistle signals after a test. Original device: 1 short=slow, 2 short=stop. Test showed wind made the whistle hard to hear. Carlos added a bright orange flag and used whistle + flag wave for "stop." New test: friend stopped in the wind. What problem did Carlos solve by improving the device?
