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.

## Description

In this lab activity, students use a PAScar Dynamics System and Data Studio software to investigate the conversion of gravitational potential energy into kinetic energy. Before beginning the experiment, students are asked to list and describe the different energies in the activity. The instructor should move analysis question 2 (Make a hypothesis, in words, relating kinetic and gravitational potential energy) to the Pre-Lab Questions section so that the students form their hypoethesis before conducting the experiment. As the activity is written, it seems the students were to form a hypothesis after the lab during the data analysis, and that isn't when a hypothesis is to be formed. The students should be forming a hypothesis that states the relationship between gravitational potential energy and kinetic energy. After conducting the experiment, the students are asked if their hypothesis was confirmed. If it was not, they are asked to modify it. There are also a series of post-lab questions that test the students' conceptual understanding of the concepts. This activity is probably best used later in the unit on energy, and the instructor should be prepared to lead a discussion about energy transfer as the cart rolls down the ramp.

#### Performance Expectations

HS-PS3-2 Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles (objects)

Clarification Statement: Examples of phenomena at the macroscopic scale could include the conversion of kinetic energy to thermal energy, the energy stored due to position of an object above the earth, and the energy stored between two electrically-charged plates. Examples of models could include diagrams, drawings, descriptions, and computer simulations.

Assessment Boundary: none

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

This activity strongly addresses the PE as the stated purpose of the lab is for the students to develop a relationship between kinetic and potential energy. The activity could be improved if it required students to develop a model instead of just using the Law of Conservation of Energy.

#### Science and Engineering Practices

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

This activity nearly fully addresses the Practice. It could more fully address the Practice if it required students to develop models instead of just using one.

#### Disciplinary Core Ideas

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

This activity fully addresses the DCI although the instructor will need to have a class discussion about energy being exchanged between systems.

#### Crosscutting Concepts

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