Which of this applies to you?

Answering these takes the parts that are not for you out of Mammal Study Merit Badge. Nothing is required, nothing is kept on the server, and nothing is ever hidden because a question went unanswered. A step that might apply to you stays on the list and is marked.

Requirement 3: how will you do the field work?

The badge says do ONE of the following. The three routes are 6 hours in the field, 15 hours across five days, and no field time at all. Decide before you start, not after two outings.

Requirement 4: which of the seven?

The badge says do ONE of the following. These range from a 500-word book report to two study skins made under the guidance of a nature centre, and two of them need somebody else to be involved.

Requirement 7: a career, or a hobby or healthy lifestyle?

The badge says do ONE of the following. Both are research and a discussion with your counselor, and neither carries a clock.
