Students learn the basic structure of a controlled experiment by analyzing experiments done by their peers - fellow teens!
1. Identify independent and dependent variables
2. Describe the control group and experimental group
3. Recognize variables that must be held constant in a controlled experiment
4. Pinpoint the number of trials completed and discuss trial size and validity of results
5. Construct experimental questions and formal hypotheses
6. Analyze methods
7. Discuss what new information we can and cannot be gleaned from the results

I have created a set of 5 mini-lessons/instructional worksheets that scaffold the skills of graphing and data analysis while building my students’ scientific background knowledge. Students graph real-world data.
1. Leveled scaffolding in making bar and line graphs.
2. Data analysis that requires using data as evidence to support conclusions.
3. Mathematical analysis including calculating averages, speed and percentages.
4. Experimental design analysis: form research questions and determine variables.
5. Graphing and analysis of data based on actual scientific studies on bird ecology and behavior.
Lesson one and two are designed to teach basic graphing and initiate thinking about experimental design and the meaning behind data.
Lessons 3 and 4 provide additional practice with reduced scaffolding so skills learned in the first two lessons can be applied by the student.
Lesson 5 has the least scaffolding in graphing and can be used as a formative or summative assessment.
