- Maya froze 180 g water overnight; the ice still weighed 180 g. Why did it stay the same?
- Observations: Sun brightest in daytime; Sirius bright at night but much dimmer. Distances: Sun 93 million mi, Sirius 51T mi. Which evidence supports the argument?
- Chen wants to compare oceans 97% to ice 2% and groundwater 0.6%; which graph helps most?
- On a farm, a cow eats grass and hay; what happens to the plant's matter?
- According to the data, how are aluminum and copper similar in more than one way? Aluminum: silver-gray, shiny, 20 g, not magnetic, conducts heat quickly. Copper: reddish-brown, very shiny, 45 g, not magnetic, conducts heat quickly.
- The observations show what happened when students used a scale to measure different objects. Claim: "Gravity pulls on objects even when they are not moving." Which piece of data best supports the claim?
- How does freezing water in cracks (hydrosphere) affect rocks (geosphere) in winter?
- Based on the model plant → animal → decomposers → soil nutrients → plant, how do decomposers recycle matter?
- Keisha poured blue water (100 g) and yellow water (100 g) into one cup. The color turned green, and the total weight was 200 g before and 200 g after. What happened to the appearance vs what happened to the total weight?
- In Sun → Algae → Tadpole, the arrow from algae to tadpole shows energy transfers by what?
- Read about a maple tree: roots absorb water/minerals, leaves take in CO2; how does matter enter?
- Maya wants to show oceans 97% and all fresh water 3%; which graph fits best?
- How does the biosphere interact with the geosphere when roots grow into rock cracks?
- In this experiment, Emma froze 100 g water into ice; it looked solid, but the scale still read 100 g. Which best explains why it looked different but weighed the same?
- Plants convert light energy from the sun into energy stored as what?
- How does heavy rain (hydrosphere) on a steep hill (geosphere) affect the land after storms?
- In this model, the biosphere affects the atmosphere by doing what during photosynthesis?
- Based on the plant growth description, what matter does a carrot plant take in from its environment?
- Gravity is a force. What kind of force is gravity near Earth?
- Marcus saw a campfire bright up close but dim far away; what about distant stars?
