  1. In the sunflower photo model, what stage comes right after the flower opens?
  2. A ball rolled down ramps: low angle 2 m/s, medium 4 m/s, high 6 m/s. Based on the pattern, what speed on a very high angle ramp?
  3. Magnet A picked up 4 paperclips, magnet B picked up 9, and magnet C picked up 15 (same kind of magnets). Why is magnet C's pull strongest?
  4. Using the data, which solution best helps sea turtles and reduces beach erosion?
  5. Amir planted two flowers from the same seeds. One was watered every day and had a bright, full bloom. The other was watered once a week and looked droopy with smaller petals. Which environmental condition affected the flower's petals?
  6. Read about the paper airplane test. What might go wrong during this test?
  7. A magnet picked up 1010 paperclips at 11 cm, 55 at 33 cm, and 22 at 55 cm; explain why.
  8. Marcus learns tornado warnings may give only about 15 minutes, so his family adds an underground storm shelter with a strong door and thick concrete walls near their house; it won't stop the tornado, but it protects people from debris. Which statement describes how the shelter reduces tornado danger?
  9. Magnet A picked up 4 paperclips, magnet B picked up 9, and magnet C picked up 15. All are the same type. Explain why.
  10. Yuki grows two tomato plants from the same parent plant. With plenty of water, one makes many tomatoes. With little water, one makes few. Which trait is influenced by the environment?
  11. Bee: egg→larva→pupa→adult→eggs; cow: born→calf→adult→calves→old; apple tree: seed→seedling→tree→apples with seeds→dies. What pattern do all these organisms share in their life cycles?
  12. Jamal wants a paper airplane that flies at least 15 feet and folds in under 10 minutes. Plane A flew 18 feet and took 8 minutes. Plane B flew 14 feet and took 3 minutes. Plane C flew 22 feet and took 12 minutes. Which plane meets all the criteria?
  13. A library needs to track borrowed books. The system must be reliable, quick, and under $100. System A: paper cards, free, takes 2 minutes per book, cards get lost sometimes. System B: computer log, costs $150, takes 1 minute, saves all records. System C: honor system, free, takes 0 minutes, no tracking. Which option is the best choice for this situation?
  14. Read about the test students are planning. Emma, Jamal, and Sofia made 3 paper airplane designs. They will throw each plane 3 times in the gym from 6 feet high and measure from the plane's nose. To make a fair test, what should they keep the same?
  15. Look at the project description: Make a classroom library display using only cardboard boxes, construction paper, tape, and scissors. It must cost $0 and be ready in under 15 minutes. What restrictions must students follow when designing their solution?
  16. All are sunflowers (same species) but they differ in which trait?
  17. To collect winter data in New York, students should record which information daily?
  18. A ball rolls from ramps and goes 100 cm, 200 cm, 300 cm. Based on the pattern, how far will it roll next?
  19. Analyze the flower data. Which trait did the offspring inherit from parents?
  20. Look at the test results. Keisha tested a parachute made from a plastic bag. It fell from 8 feet in 3 seconds and landed 6 feet away from the target. The class saw one string was shorter than the others, and it drifted sideways. Which improvement would solve the problem found in the test?
