20 questions. Answer them in any order, then submit to see your score and every explanation.
- Read about the rain collector design. Yuki's group checks if it works after a storm. Success means it collects at least 1 gallon, keeps out dirt and leaves, and does not overflow or spill. How can students tell if their rain collector works well?
- A wind-up car goes 50 cm, 48 cm, 52 cm, 49 cm, 51 cm. Can students predict the next result?
- A block slides: Monday cm, Tuesday cm, Wednesday cm, Thursday cm. If the pattern stays about the same, what on Friday?
- A ball rolled fast, slowed down, and stopped after 5 m. Use evidence to explain why it stopped.
- In Kansas, Sofia sees a dark green sky, large hail, and a loud roar like a train. A rotating funnel drops from a thunderstorm and tears roofs off houses, tosses cars, and throws sharp debris through the air. The tornado siren sounds, and people hurry to a basement because walls can collapse and flying debris can hurt people. Based on the description, what weather hazard is described?
- The claim is "Monkeys and tree frogs thrive in rainforests, but cacti struggle." Use evidence to support.
- Look at the plant marker project description. Garden club must make 20 plant markers in 45 minutes. Students can use only popsicle sticks, markers, and clear tape from the art closet, and they cannot buy anything new. What rules must students follow about materials, time, or money?
- A recycling helper must quickly tell steel cans from aluminum cans. What magnetic property makes this solution work?
- In this rainforest habitat, it is hot and rainy with tall trees; which organism thrives?
- Read about the test: Emma tests if bigger wings make paper airplanes fly farther. She throws 3 times for each wing size. If she throws harder sometimes, results change. Which shows something that could make the test unfair?
- A ball rolls 100 cm, 200 cm, 300 cm on low, medium, high ramps. Predict next distance.
- Read about the problem and solutions. Students waste time getting art supplies from the cabinet. Solution 1: create supply caddies for each table. Solution 2: use a rolling cart to deliver supplies. Solution 3: give each student a personal supply box. What is one way the solutions are different from each other?
- Zebra evidence: lone zebra was caught and killed; herd of 50 ran together, stripes confused lion, lion gave up; herd lookouts spotted predators early. Which argument correctly uses the observations?
- In tug-of-war, the rope stayed still; are forces balanced or unbalanced?
- Maya found coral fossils in rocks on a mountain far from the sea; why is this evidence of a past ocean?
- Yuki lives near the Atlantic coast and hears a big storm is coming from the warm ocean. Strong winds knock down trees, and storm surge floods the beach town with ocean water. Which weather hazard has these characteristics?
- A class wants a pet that is active during class, easy to care for, and interactive. Option A: hamster is active in the day, eats cheap pellets, cage cleaned weekly, can be held. Option B: fish is visible all day, fed daily, tank cleaned monthly, cannot be held. Option C: hermit crab hides often, needs special food, easy care, can be held. Based on the criteria, which option should students choose?
- In this pond habitat with freshwater plants and mud, which organism would struggle most?
- When collecting spring data in Ohio, which method will give the most useful weather data?
- Put butterfly stages in order: egg, caterpillar, chrysalis, adult, lays eggs. Which is correct?
