NEW! This resource contains quality, EDITABLE sample NGSS assessment questions and performance tasks for the Earth and Space Sciences Performance Expectation MS-ESS1-2. Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system. It includes 5 questions or tasks total which can be edited, copied and pasted into various forms of assessments to align to the NGSS. Links to external resources to help teach the standard are also included.

Use these sample questions for: pre-assessments, check-ins or quizzes, unit tests, and/or for your professional growth objectives!

The questions cover the 3 dimensions of the NGSS and include:

• constructed response questions
• performance tasks
• questions with multiple components

This set of questions require students to use Science and Engineering Practices as well as Crosscutting Concepts to demonstrate understanding of the Disciplinary Core Ideas. The SEPs and CCCs are listed for each PE. Keep in mind that the tasks require more time than a standard test question, therefore, there should be fewer questions on a test which allows for more time to solve the problems.

SAMPLE TASK:

Observe the image of the student’s model of the earth and sun system (provided in document). Use this model to answer the questions below.

a. Fill in the table by stating which object was used to represent each part of the system (provided in document).

b. If you were to add Earth’s moon to this model, what would you do? Add it to the student’s model and label it as well as its orbit.

c. Explain what would happen to the ball if the rope was suddenly cut while spinning very fast. How is this both similar to and different from what would happen to a planet if there suddenly was no gravity?

d. Tetherball is a game that is played with a similar setup. A ball is tethered to a pole using rope and two opponents take turns hitting the ball in opposite directions. Imagine multiple tetherball equipment (pole, rope, and ball) set up in stations in an area. Would combinations of stations be considered a solar system or a galaxy? Explain your answer and be sure to use gravity in your response.

This product includes:

1. Background info on NGSS assessments and tasks
2. 5 EDITABLE questions, tasks, etc. total
3. Answer Key
4. Ideas for differentiation
5. External links to resources to help teach the standard

NGSSMS-ESS1-2
Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system. Emphasis for the model is on gravity as the force that holds together the solar system and Milky Way galaxy and controls orbital motions within them. Examples of models can be physical (such as the analogy of distance along a football field or computer visualizations of elliptical orbits) or conceptual (such as mathematical proportions relative to the size of familiar objects such as students’ school or state). Assessment does not include Kepler’s Laws of orbital motion or the apparent retrograde motion of the planets as viewed from Earth.
