PRISMS: Phenomena & Representation for Instruction of Science in Middle School

Rate This Resource
This is a phenomenon reviewed for the following learning goal:

Interactions between organisms may be for nourishment, reproduction, or protection and may benefit one of the organisms or both of them.

Summary

The narrated video shows the predation of mongoose by marabou storks and describes marabou storks hunting and eventually taking an unattended mongoose pup. Additionally the video shows and describes the way mongoose packs work together to protect their young. It addresses the parts of the key idea that  interactions between organisms may be for nourishment or protection and may benefit one of the organisms or both of them. It is likely to be comprehensible to middle school students.

Limitations: None

Suggestions to improve effectiveness: Make explicit the idea that this interaction serves the predator's needs for nourishment. Also make explicit the idea that mongoose live in packs and work together to protect their young because it increases the chances of survival.

Content alignment

The resource addresses the actual substance of the learning goal rather than just the topic.

Explanation

The resource states "while the mongooses are busy with the termites, the marabou stork have their sites set on the mongoose babies." The resource further shows and describes the mongooses' cooperative efforts to fend of the predator and refers to the mongoose as "scrappy fighters." The stork is referred to as a predator and the mongoose is referred to as predator turned prey. The resource does not explicitly address whether or not the mongoose benefit from this cooperative behavior though it can be inferred.

Scope

The resource addresses the indicated part of the learning goal:

Explanation

[Interactions between organisms may be for nourishment], reproduction, [or protection and may benefit one of the organisms or both of them.] Some species have become so dependent on each other that neither could survive without the other.

Sophistication

The resource correctly reflects the level of sophistication of the learning goal.

Explanation

The resource uses terminology appropriate for this learning goal.

Notes for Teachers

Make explicit the idea that this interaction serves the predator's needs for nourishment. Also make explicit the idea that mongoose live in packs and work together to protect their young because it increases the chances of survival.

Quality of instructional support

Is the relationship between the phenomenon and the learning goal made clear?

Yes—The relationship between the phenomenon and the learning goal is made clear.

The phenomenon of predation and protection is readily observed in this example. The mongoose is referenced as "predator turned prey" which reinforces the idea that a number of interactions between organisms exist and that these relationships are based on a particular need.

Is the phenomenon likely to be comprehensible to students?

Yes—The phenomenon is likely to be comprehensible to students.

The clip presents strong evidence supporting the ongoing predator-prey relationship between the mongoose and marabou stork. The narration notes: "Where there are mongoose pups, there will soon be voracious storks and the battle is on a third time. One pup gets separated and ...a stork picks him off despite the pack's best effort, the storks win this battle."

Is the phenomenon first-hand (when appropriate or practical) or vicarious through use of video, pictures, or text?

Yes—The phenomenon is first-hand (when appropriate or practical) or vicarious through use of video, pictures, or text.

The phenomenon is observed through the use of video. Narration aids in the explanation of the organisms' interactions.

Is the phenomenon efficient, i.e., the benefits justify the costs in time and money?

Yes—The phenomenon is efficient: the benefits justify the costs in time and money.

The clip is free and approximately 3 minutes long.
