Question

q3. (s c.6.n.1.4) several student groups test how the angle of a ramp affects the speed of a toy car. their results are similar but not identical. why should they share their methods and results?

a. to decide which group is correct and which is wrong

c. to identify possible errors and improve accuracy

b. to ensure all groups change their answers to match

d. to avoid repeating the experiment in the future

Explanation:

Sharing methods and results allows students to compare experimental set - ups and data. This helps in finding potential errors in their procedures or measurements, which in turn improves the accuracy of the overall findings. It's not about determining right or wrong in a competitive sense, making everyone's answers match, or avoiding future experiments.

Answer:

C. To identify possible errors and improve accuracy
