Lesson Title: On Target Challenge
May 11, 2012

Unit: Engineering - Challenges

Grade Levels: 7-9

Connection To Curriculum: Newton's First Law, Potential and Kinetic Energy, Acceleration Due to Gravity, Vectors, Trajectory and Measurement

Teacher Prep Time: 15-30 minutes

Lesson Time Needed: 1 hour

Complexity Basic

Keywords: engineering challenge, scientific method, rockets, moon, Newton's laws, engineering design process, moon, Mars, acceleration, vector, trajectory, potential energy, kinetic energy, LCROSS

Materials:

(per zip line)
9 feet (3 m) of smooth line (e.g., fishing line or kite string)
Index card
Marble
Masking tape
Paper clip
1 medium-sized paper cup
Scissors
Target drawn on a piece of paper
 

Description
Students will modify a paper cup so it can zip down a line and drop a marble onto a target.

Objectives
Students will:
• Apply the engineering design process.
• Modify a cup to carry a marble down a zip line.
• Test their cup by sliding it down the zip line, releasing the marble and trying to hit a target on the floor.
• Improve their system based on testing results.

Lesson Activities and Sequence
Access the On Target activity.

  1. Introduce the challenge: Tell kids how NASA will use the LCROSS spacecraft to search for water on the moon (scripted in the Leader Notes).
  2. Brainstorm and design: Students should be working in cooperative groups to develop a group design and using individual journals to record their decisions, design sketches, test results, etc.
  3. Build, test, evaluate and redesign: Test data, solutions, modifications, etc., should all be recorded in their journals individually.
  4. Discuss what happened: Ask the students to show each other their modified cups and talk about how they solved any problems that came up.
  5. Evaluation: Using the students' journal entries, assess their mastery of content, skills and the engineering design process.
