- After a storm, rainwater (hydrosphere) flows downhill over soil (geosphere); what happens to land?
- Which evidence best supports the argument that the sun appears brighter because it is closer?
- What form does the sun's energy take when stored in a plant's food?
- Emma used hand sanitizer; it felt wet, then disappeared from view—do the alcohol particles still exist?
- Based on this incomplete argument, what reasoning best connects the evidence to the claim? Claim: Gravity pulls objects toward Earth. Evidence: When Maya dropped a key, a marker, and an eraser, each one fell to the floor.
- A hummingbird drinks nectar; energy from the food is used for what?
- In Van Helmont's experiment, the tree gained 164 lb but the soil lost only 0.1 lb. Based on the evidence, what does this show about the idea that soil provides most plant matter?
- Maya could see through the cup because it was clear. What observable property helps describe it?
- Yuki sees mold and bacteria breaking down old bread. How do decomposers help recycle matter?
- A cup weighed 200 g before water froze; after freezing it weighed 200 g. How do the weights compare?
- Sofia measured 110 g total before stirring sugar and water; after dissolving, it was 110 g. What do measurements show?
- Two gray, hard samples looked very similar, so color and hardness didn't help. The students used a magnet and found only Material A was attracted. What made magnetism a useful property for identification in this situation?
- Maya measured Liquid X as 50 mL; which tool measured the volume?
- Students compared wood types: Oak (dark brown, 80 g for 10 cm piece, hard, visible grain), Pine (light yellow, 45 g for 10 cm piece, softer, visible grain), and Balsa (cream, 15 g for 10 cm piece, very soft, fine grain). Based on multiple properties, which material is most likely balsa wood?
- In the ocean, a fish is an example of which Earth system?
- Which elements do plants get mainly from air and water, not soil minerals?
- Four white fabrics felt flexible, so color and feel did not help. Water soaked into Fabric A fast but beaded on Fabric C. What made absorption a good distinguishing property?
- Marcus left dry ice on a counter; it got smaller, then gone. What is true about its particles?
- Based on these observations, which argument is strongest about whether gravity affects all objects near Earth? A student dropped a plastic spoon, a metal key, and a rubber eraser. All three fell to the floor. A helium balloon was released and rose upward.
