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.

Description

The short 6-and-a-half-minute video provides background information for the teacher about the role of water on the planet, the extent of it across the globe (and how to visualize this extent) and what the planet would look like if it were removed.

Performance Expectations

2-ESS2-3 Obtain information to identify where water is found on Earth and that it can be solid or liquid.

Clarification Statement: none

Assessment Boundary: none

This resource was not designed to build towards this performance expectation, but can be used to build towards it using the suggestions provided below.

Comments about Including the Performance Expectation
This video would support teachers in understanding where water occurs on the planet, and the extent that it is found in every living thing, as well as only on a relatively thin layer of the planet. The video is useful because it provides some great imagery of the extent water covers the planet, compares it to other familiar planets, and uses an orange peel to visualize how thin the layer of water is on the planet. Teachers would appreciate some of this background information when addressing the Performance Expectation through other instruction. One problem with this resource is that the narrator uses the word “hell” to describe the lack of water and the atmosphere of Venus.

Science and Engineering Practices

This resource was not designed to build towards this science and engineering practice, but can be used to build towards it using the suggestions provided below.

Comments about Including the Science and Engineering Practice
The video is meant to support the teacher to obtain information and then convey some of the important relationships between water, its location and prevalence on Earth, and the vitalness of it for all living things.

This resource appears to be designed to build towards this science and engineering practice, though the resource developer has not explicitly stated so.

Comments about Including the Science and Engineering Practice
The video supports teacher’s understanding of the relative extent of water on the planet’s surface especially with respect to its importance.

Disciplinary Core Ideas

This resource was not designed to build towards this disciplinary core idea, but can be used to build towards it using the suggestions provided below.

Comments about Including the Disciplinary Core Idea
The video also touches on the fact that water is found in all plants and animals. It shows the planet without water on its surface and that land only cover 29% of the surface. Of course, this number is not meaningful to the students, but the teacher can use this information to inform teaching of this concept in a qualitative way.

Crosscutting Concepts

This resource was not designed to build towards this crosscutting concept, but can be used to build towards it using the suggestions provided below.

Comments about Including the Crosscutting Concept
The planet area which is covered by land compared to the area covered by water is a small ratio. The layer of water is thin as compared to the mass of the planet. The video also shows the planet with drops of fresh and seawater next to it to show that it astoundingly small in scale.

Resource Quality

  • Alignment to the Dimensions of the NGSS: The video is motivated by a meaningful and authentic phenomenon. It addresses the Core Idea, Practice, and Crosscutting Concept. This leads toward deeper understanding of the Performance Expectation. The Disciplinary Core Idea addressed in the video is a lever for deeper learning as students move toward more sophisticated understanding of water in Earth’s systems as they move up in grade. The phenomenon authentically touches on a real-world problem or phenomenon that scientists deal with constantly.

  • Instructional Supports: The video is meant to provide background information for the teacher before embarking on lessons that align with the Performance Expectations.

  • Monitoring Student Progress: The video is a resource for teachers who want background information for the Performance Expectation. There is no way to monitor student progress.

  • Quality of Technological Interactivity: Video quality is superior.
