Transcript of Science & Engineering Practices

The 6 practices scientists & engineers use to solve problems.
Science & Engineering Practices
Scientists ask testable questions
Engineers solve problems
Use research to form hypotheses
Asking Questions & Defining Problems
Engineers develop or modify/revise models
Models show relationships between variables...
Independent Variable
- The factor you change or test.
Dependent Variable
- The factor(s) that responds to that change.
Controlled Variables
- The factors that stay constant.
Developing & Using Models
Identify the independent & dependent variables
Identify all controlled variables.
How much data is needed?
Control group is a comparison, the experimental group receives the changed variable.
Planning & Carrying Out Investigations
Identify trends & patterns in data.
Using graphs, statistics, probability, mathematics, & digital tools.
Analyzing & Interpreting Data
Communicate clearly & persuasively.
Use valid & reliable evidence from multiple sources
Respectfully provide & receive critiques
Engaging in Argument From Evidence
Example: You want to know if eating Snickers will make you a faster runner. To test this you decide to time yourself run once around a track with out eating Snickers. You return to the same track the next day, eat the Snickers and time yourself run the same distance.
Before we begin designing an experiment, let’s review the parts of an experiment!
I wonder... what happens to the mass of gum after it has been chewed for 10 minutes?
