This document outlines the components of an experimental design, including stating a testable question and hypothesis, describing the independent and dependent variables, assigning team member duties, outlining procedures, collecting data in a table and graph, and drawing a conclusion based on the evidence. It provides a template for planning and documenting a scientific experiment.

1. Experimental Design Diagram
Chart and Data Table may change with each Investigation
1. Testable Question:
What is the effect of _______________________________(IV) on the
_____________________________________________________(DV)?
2. Hypothesis:
If the ______________________________(IV) changes,

then the ___________________________________(DV) will increase/
decrease/ stay the same.
