Which Experimental Design Process step is missing?

• Specify Requirements

• Define Criteria

• Construct a Hypothesis

Answer explanation

The missing step in the Experimental Design Process is 'Construct a Hypothesis'. This step involves formulating a testable statement based on the specified requirements and criteria, guiding the experimental investigation.

Which step is missing from these processes?

The variable that is changed on purpose in an experiment by a scientist

• Independent Variable

• Dependent Variable

• Constants

Answer explanation

The independent variable is the one that is intentionally changed by the scientist to observe its effect on the dependent variable. This is a fundamental concept in experimental design.

A step-by-step list of how to carry out an experiment

• Guidelines

• Directions

• Instructions

• Procedure

Answer explanation

The correct choice is 'Procedure' as it specifically refers to a detailed, step-by-step list of how to carry out an experiment, distinguishing it from more general terms like guidelines or directions.
