q4. (s c.6.n.1.4)
two groups test how fertilizer affects plant growth. group a’s plants grow much taller, while group b’s plants show little change.
what should the students do first to resolve this difference?
compare procedures to see if conditions were different
ignore group b’s data
repeat the experiment without checking methods
assume group a is correct

Explanation:

In scientific experiments, when there are inconsistent results between groups, the first - step is to check if the experimental procedures and conditions were the same for both groups. This helps in identifying any potential sources of error or bias. Ignoring data, repeating without checking methods, or assuming one group is correct are not valid scientific practices.

Answer:

Compare procedures to see if conditions were different
