Question

practice it!
drag and drop the words or phrases that accurately complete the columns comparing investigations.

possible hypothesis no hypothesis hypothesis
possible variables no variables
counting/observing controlled

blue boxes: no variables, investigation, variables, describing data, descriptive, experimental, replication, classification, comparing groups, comparative

Explanation:

To solve this, we analyze the types of scientific investigations (descriptive, comparative, experimental) and their characteristics:

Descriptive Investigation (counting/observing, no hypothesis, no variables):

• Matches: no hypothesis, no variables, counting/observing, describing data, descriptive, classification (classifying is part of describing).

Comparative Investigation (comparing groups, possible hypothesis, possible variables):

• Matches: possible hypothesis, possible variables, comparing groups, comparative.

Experimental Investigation (controlled, hypothesis, variables):

• Matches: hypothesis, variables, controlled, experimental, replication (experiments can be replicated).

Filling the Columns:

1. First Column (Comparative/Descriptive setup for possible elements):

• Top: possible hypothesis (for comparative/descriptive with tentative hypotheses)
• Middle: possible variables (for investigations with potential variables)
• Bottom: comparative (or descriptive; here, comparative fits “possible hypothesis/variables”)

1. Middle Column (Descriptive Investigation):

• Top: no hypothesis (descriptive investigations observe without a hypothesis)
• Middle: no variables (descriptive focuses on observing, not manipulating variables)
• Bottom: counting/observing (core of descriptive: observing/counting phenomena)

1. Right Column (Experimental Investigation):

• Top: hypothesis (experiments test a hypothesis)
• Middle: variables (experiments manipulate/measure variables)
• Bottom: controlled (experiments control conditions)

Final Drag-and-Drop Matches (example structure):

• First Column (top to bottom): possible hypothesis, possible variables, comparative (or descriptive)
• Middle Column (top to bottom): no hypothesis, no variables, counting/observing
• Right Column (top to bottom): hypothesis, variables, controlled

(Note: The exact “drag-and-drop” targets depend on the column headers, but the key is matching each investigation type to its traits.)

For example, if columns are “Comparative”, “Descriptive”, “Experimental”:

• Comparative: possible hypothesis, possible variables, comparing groups, comparative
• Descriptive: no hypothesis, no variables, counting/observing, describing data, descriptive, classification
• Experimental: hypothesis, variables, controlled, experimental, replication

Answer:

(Example drag-and-drop mappings, adjust to column headers):

• First (left) column: possible hypothesis, possible variables, comparative
• Middle column: no hypothesis, no variables, counting/observing
• Right column: hypothesis, variables, controlled

(Additional terms: descriptive → middle; experimental, replication → right; classification → middle; describing data → middle; investigation → all columns as the base term)
