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

Video of dolphins working together to fish by creating a mud “net” around a school of fish to capture them for easy feeding by the dolphins. Students can watch this phenomenon to gather evidence of animal groups working together to help members survive.

Performance Expectations

3-LS2-1 Construct an argument that some animals form groups that help members survive.

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 provides an example of how groups of dolphins cooperate to help the members survive. It can be used to meet the performance expectation by having students use the information they gather to construct arguments. In addition to watching this video, students can gather information about how animals in groups help each other to survive from other videos and books. Perhaps each student (or each group of students) might become experts on different types of animal groups. Then, they can share what they learned with others by creating a poster, digital presentation, mini-book, or oral presentation. The class can participate in a science talk focusing on the question: Why do some animals live in groups? In this discussion, students can provide evidence from their reading/research to support their claims and a class chart can be created of all the different ways that animal groups are advantageous.

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
Students can obtain information from this video and other resources, then summarize what they learned to explain how animals in groups help each other survive.

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
After students gather information from the video (and perhaps other sources), they can identify specific animal groups that help animals obtain food. A class chart or table could be created. For instance, this video can be compared with the Coming Ashore video (dolphins herding fish onto the shore) and/or the Bubble Net Fishing video (humpback whales capturing fish with bubbles) to compare different ways that marine mammals work together to obtain food. How are these methods alike? Different? Why? Students could also compare with other animal groups that don’t live in the ocean.

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 teacher can introduce or review the concept of systems and show examples of how animal groups act like a system with individual parts performing individual functions.
