LA algebra 2 Comprehensive Curriculum unit 5

1. Use quadratic equations to model real-life situations
2. Capture and upload video
3. Analyze video useing Logger Pro3 computer software
4. Prepare power point presentation

1. Discuss real-life situations (on campus) that produce a parabola-shaped curve.
Examples: kicking a soccer ball, shooting a free-throw (basketball), bouncing a ball to another person, pole-vaulting, throwing an object from a height, shooting an arrow at a targer, etc.
2. Make a list of student suggested situations on the board.
3. Create groups (3-4 students per group)
4. Randomly assign groups to a real-life situation
5. Students use Tool Factory mobile digital camera lab to capture a video of their situation.
6. In the computer lab, students upload the video to Logger-pro 3 computer software
7. Use Logger-pro 3 software to analyze video.
8. Use data to create a power-point presentation of situation and analysis (be sure to include video in presentation).

1. Teacher observation
2. Oral discussion
3. Group project
4. Class presentation
This activity gives students a chance to get out of the classroom and actually "see" the math; which does not happen often with higher-level mathematics
Cross-Curriculum Ideas
Physics class creates a project (roller-coaster, cannon, etc) and math class videos and analyzes the project.
Math class videos physical education students (long jump, pole-vault, archery, etc) and share findings.
Social Studies can recreate a battle situation and math class can analyze the data and share the results.
Video situations that are not parabolic and analyze the graph produced. Relate the graph produced to previously studied functions.
