Note
This resource, vetted by NSTA curators, is provided to teachers along with suggested modifications to make it more in line with the vision of the NGSS. While not considered to be “fully aligned,” the resources and expert recommendations provide teachers with concrete examples and expert guidance using the EQuIP rubric to adapted existing resources.

Reviews

Description

This review is  for a series of lessons that begin with the introduction to the concepts of momentum and impulse, labs investigating the conservation of momentum, and a final project in which an egg vehicle is created to protect the egg from damage when it crashes. Detailed teacher notes and background is included in the lesson descriptions including assessments throughout the lessons.

Performance Expectations

HS-PS2-3 Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.

Clarification Statement: Examples of evaluation and refinement could include determining the success of the device at protecting an object from damage and modifying the design to improve it. Examples of a device could include a football helmet or a parachute.

Assessment Boundary: Assessment is limited to qualitative evaluations and/or algebraic manipulations.

This resource is explicitly designed to build towards this performance expectation.

Comments about Including the Performance Expectation
The lesson plan introduces all of the background knowledge needed to complete the engineering challenge of protecting an egg from breaking when dropped from a tall height. It also provides a suggested lab report formal assessment as well as group discussion questions following the engineering challenge. As an extension, the instructor can ask the learners to repeat the challenge and refine their device to get a better result than their first attempt.

Science and Engineering Practices

This resource is explicitly designed to build towards this science and engineering practice.

Comments about Including the Science and Engineering Practice
The lesson plan offers questions for the students to answer as they work through the unit, and culminates with a design project. It often suggests that students complete practice problems on a topic, but these are not provided with the resource. The instructor will need to provide a significant amount of instruction relating to the approach to solving these types of problems by diagramming the situation, identifying the forces involved, and applying the conservation of momentum to the collision.

Disciplinary Core Ideas

This resource is explicitly designed to build towards this disciplinary core idea.

Comments about Including the Disciplinary Core Idea
The lesson sequence covers the qualitative investigation of momentum as well as suggests that the learner complete quantitative calculations involved with the conservation of momentum. The lesson does not give any direct guidance in completing these calculations however.

Crosscutting Concepts

This resource is explicitly designed to build towards this crosscutting concept.

Comments about Including the Crosscutting Concept
The design project includes designing a solution that creates the desired effect of preventing the egg from breaking when dropped from a tall height.

Resource Quality

  • Alignment to the Dimensions of the NGSS: The lesson plan aligns to the performance expectation, “Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.” exactly. It begins with background investigations for the student to learn about momentum and collisions and culminates with an engineering challenge where students design a device to protect an egg from breaking when dropped from a tall height..

  • Instructional Supports: The lesson plan has a detailed description of how to implement the lesson and assess the students throughout the sequence of activities but does not provide any practice problems. It also does not suggest how to introduce the concepts of momentum and impulse to the learners.

  • Monitoring Student Progress: Methods of assessment are included throughout the lesson plan including for the engineering challenge at the end of the lessons but no practice problems for the conservation of momentum and impulse are provided.

  • Quality of Technological Interactivity: This is a lesson plan not an interactive activity.
