A student claims the thermometer readings are quantitative evidence. Which evidence best supports the claim?
A student claims repeated trials made a ramp result more reliable. Which evidence best supports the claim?
A student claims an insulation comparison was a fair test. Which evidence best supports the claim?
A student claims mass data had a source of error. Which evidence best supports the claim?
A student claims the class used SI units. Which evidence best supports the claim?
A student claims density stayed the same for different sample sizes. Which evidence best supports the claim?
Use the food-web model. A student claims owls get energy from mice. Which evidence best supports that claim?
A student claims reaction time was the dependent variable. Which evidence best supports the claim?
A student claims a hypothesis was tested, not just guessed. Which evidence best supports the claim?
Twenty pill bugs entered a tray, and 14 moved to the moist side. Claim: pill bugs prefer moisture. Which reasoning links the evidence to the claim?
Sugar dissolved in 20 seconds in warm water and 55 seconds in cold water. Claim: temperature affects dissolving rate. Which reasoning fits?
A yeast bottle with sugar made an 8 cm balloon. Without sugar, the balloon was 1 cm. Claim: yeast uses sugar to produce gas. Which reasoning fits?
Fertilized plants averaged 18 cm, and control plants averaged 12 cm. Claim: fertilizer increased growth. Which reasoning explains why the control matters?
Plane A flew 4 m, 5 m, and 15 m, and Plane B flew 6 m, 7 m, and 6 m. Claim: Plane B was more consistent. Which reasoning fits?
A sealed bag reaction had a mass of 52 g before and after. Claim: mass was conserved. Which reasoning connects the evidence?
A class observes that dropped objects accelerate downward near Earth. Claim: a scientific law can describe this pattern. Which reasoning fits?
An empty balance read 5 g, and all object masses were 5 g too high. Claim: the data had systematic error. Which reasoning fits?
As salt concentration increased, plant height decreased. Claim: salt concentration affected growth. Which reasoning connects the variables?
A liquid turned cloudy and warmed from 22 to 28 degrees Celsius. Claim: a reaction occurred. Which reasoning best connects the evidence?
Response: “The lamp helped the bean plant grow because the lit plant grew 8 cm and the dark plant grew 2 cm.” Which part is the claim?
Response: “The stream is polluted because nitrate measured 15 mg/L, above the safety limit. Too much nitrate makes algae overgrow.” Which part is evidence?
Response: “The marble rolled farther on tile: 3.0 m on tile, 1.1 m on carpet, because tile has less friction.” Which part is reasoning?
Response: “The magnet with more coils was stronger because it lifted 18 clips, while the other lifted 7 clips.” Which part is the claim?
Response: “The larger parachute fell slower because its mean fall time was 4.8 s, compared with 2.1 s. A larger canopy has more air resistance.” Which part is evidence?
Response: “The cup wrapped in wool stayed warmer, at 52 °C versus 38 °C, because wool trapped more air, which slows heat transfer.” Which part is reasoning?
Response: “The unknown sample is denser than water because 10 mL had a mass of 15 g.” Which part is the claim?
Response: “The trial had an error because the ruler started at 1 cm instead of 0 cm, and measurements must start at zero to be accurate.” Which part is evidence?
Response: “The warmer jar grew more mold, 12 spots versus 3 spots, because higher temperature speeds many mold life processes.” Which part is reasoning?
Response: “The saltwater group grew less: the mean height was 4 cm, while freshwater plants averaged 9 cm.” Which part is evidence?
