#### Transcript of Science & Engineering Practices

The 6 practices scientists & engineers use to solve problems.
Science & Engineering Practices
Engineers solve problems
Research
Use research to form hypotheses
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
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.
INDEPENDENT VARIABLE –
DEPENDENT VARIABLE -
CONTROL VARIABLES –
CONTROL GROUP –
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?
What tools can you use to research in my classroom?
Constructing Explanations & Designing Solutions
The end product of science in an
explanation
.
Explanations or
claims
must be supported with
evidence
.
Explanations with enough evidence can become
theory
or
scientific law
.
The end product of engineering is a
solution
.
The best solution meets all criteria &
constraints
.
