Question

drag and drop the words or phrases that accurately complete the scenarios.
investigation #1: what happens when you add a mentos to a bottle of diet soda?
type:
benefit: no interference
limitation:
investigation #2: which bottle of soda shows the greatest reaction when mentos is added?
type: comparative
benefit: comparing two or more things
limitation:
investigation #3: how does the amount of mentos affect its reaction with a fixed amount of diet soda?
type: experimental
benefit:
retest for validity variables not controlled
researcher bias descriptive replication
human error hypothesis required
interferes with environment multiple trials
research required

Explanation:

For Investigation #1: Since it's just observing what happens (describing the event), the type is descriptive. Limitation for descriptive could be researcher bias (as the description might be influenced by the observer's perspective).
For Investigation #2: In comparative studies, a common limitation is variables not controlled (as when comparing, if other factors aren't held constant, results can be skewed).
For Investigation #3: In experimental studies (where you manipulate a variable - amount of Mentos here), a benefit is multiple trials (to ensure reliability of results).

Answer:

Investigation #1:
Type: descriptive
Limitation: researcher bias
Investigation #2:
Limitation: variables not controlled
Investigation #3:
Benefit: multiple trials
