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:
limitation:

Explanation:

To solve this, we analyze each investigation:

Investigation #1

• Type: Descriptive (since it's observing what happens, no comparison or variable manipulation).
• Limitation: Can't establish cause - effect (only describes the event, not why or how factors influence it).

Investigation #2

• Limitation: Multiple variables (when comparing different soda bottles, factors like brand, sugar content, carbonation level might vary, hard to control all except the one intended for comparison).

Investigation #3

• Benefit: Establishes cause - effect (by manipulating the amount of Mentos (independent variable) and observing reaction with fixed soda, we can see how the amount causes changes in the reaction).
• Limitation: Simplified conditions (lab conditions with fixed soda amount might not reflect real - world, more complex scenarios).

Filling the Blanks:

• Investigation #1:

Type: \(\boldsymbol{\text{Descriptive}}\)
Limitation: \(\boldsymbol{\text{Can't establish cause - effect}}\)

• Investigation #2:

Limitation: \(\boldsymbol{\text{Multiple variables}}\)

• Investigation #3:

Benefit: \(\boldsymbol{\text{Establishes cause - effect}}\)
Limitation: \(\boldsymbol{\text{Simplified conditions}}\)

(Note: If there was a list of drag - and - drop options, we'd match these descriptions to the options. Since options aren't provided, we give the typical answers for such scientific investigation type questions.)
