- Students examined dark blue fabric: soft, flexible, woven texture, lightweight, and absorbed water quickly. Which properties were observed?
- Based on these observations, which argument is the strongest and most complete (claim, evidence, reasoning) about gravity near Earth? Observation: A student jumped straight up and always came back down to the ground.
- Comparing these mixtures, which one is most likely a physical change (no new substance formed)? Mixture A: A metal paper clip left in wet air for several days turns orange-brown and flaky. Mixture B: Sugar stirred into warm water disappears, and the water tastes sweet. Which choice best explains why one is physical and the other is chemical?
- When you drop a toy car, it falls toward the ground instead of sideways. What does this direction tell you about the cause of falling?
- How does filtration science help communities build rain gardens to reduce water pollution?
- Based on these observations, a student wrote an incomplete argument: Claim: Gravity pulls objects toward Earth. Evidence: When I let go of my water bottle, it fell to the floor. Which reasoning best connects the evidence to the claim?
- To investigate whether mixing creates a new substance, Maya mixes yeast, sugar, and warm water. Her steps are: 1) Mix 1 tsp yeast, 1 tsp sugar, and 1/2 cup warm water in a clear cup. 2) Watch for 10 minutes. 3) Write down what happens. What should Maya do first to make her investigation plan stronger?
- Chen wants a fair test to compare how fast sugar dissolves in cold water versus warm water. He plans to use two clear cups, 1/2 cup water in each, and 1 tsp sugar in each. Which action best keeps the test fair?
- On a farm, a cow eats grass and hay; how does matter from plants help it grow?
- Two students disagree about a mixture. Student A says, "A new substance formed because the powder disappeared in water." Student B says, "No new substance formed because there were no bubbles, no temperature change, and we could get the powder back by evaporating the water." Based on the evidence, who is correct and why?
- How does this data support the argument that distance is the main cause of brightness differences?
- Three white powders looked the same: salt, sugar, and baking soda. Dissolving in water didn't help because all three dissolved. Adding vinegar made only one powder fizz. Why did the vinegar test help distinguish the powders?
- Look at the line graph of daylight; which month has the least daylight hours?
- Two materials were both brown and smooth, so those properties did not help. One was magnetic, very heavy for its size, and sank; the other was not magnetic, light for its size, and floated. Explain why different properties are needed to distinguish materials here.
- A cheetah eats meat; what does food energy help the cheetah do?
- How does conservation of matter help communities recycle to reduce landfill waste?
- The model shows that energy in the plant's food originally came from what?
- In a prairie, a horse eats wheat stems; how does wheat matter become horse matter?
- A bar graph shows oceans 97%, ice 2%, groundwater 0.6%; what y-axis scale is best?
