3-LS2-1: Construct an argument that some animals form groups that help members survive.
SEP: Engaging in arguments from evidence
I liked how the video explained that an argument is not a fight, it helps create the best explanation.  For this standard, students will choose a social animal- one that lives in a group- to construct an argument about how this social living helps the animal survive.  Students will use evidence and then critique one another as part of the peer review process in science.

DCI: LS2-D- Social Interactions and Group Behavior
In their argument for why the animal they selected lives in a group to help members survive, students will include evidence that by working together they animal does better and then passes this on.  They will show how the group helps with food and defense.  It is almost important to include the size and function of the group.

CCC: #2- Cause and Effect
For this standard, students will be able to explain group patterns and how this effects the group.  Students could also explore what might happen if an animal is isolated form the group- what effect will this have?

You are so right.  Listening to the video again, an argument it is a passionate voice that students possess and they are aloud to share it in a positive manner.
