Beavers' Homes

I. How does a beaver build a home
    A. First, it builds a dam in a selected spot
        1. Places stones, sticks, and mud in streambed
        2. Makes dam high enough to flood area
    B. Next, it builds canals
        1. Canals reach from dam to logs' source
        2. Canals used to float sticks and logs
    C. Finally, it builds a lodge
        1. First home is in a bank
        2. High water forces it to dig higher
        3. Eventually piles mud and sticks above ground

II. How does finished home look
    A. Room can be 2' high and 4' wide above water
        1. Airtight walls plastered with mud
        2. Air hole in top
    B. Two entrances to home

The Mental Proof & Self-Audit Questions (Textbook Page 20)

Page 20 teaches students how to audit their own outlines by asking analytical proof questions:

Proof 1 (Paragraph-to-Topic Alignment):
Paragraph 1 explicitly poses: "How does a beaver build a home?" which directly forms Roman numeral I. Paragraph 2 asks "How does finished home look" which forms Roman numeral II.

Proof 2 (Chronological Subtopic Proof under I):
Subtopics I. A, I. B, and I. C use sequence transition adverbs (First, Next, Finally) to systematically document the three engineering stages: dam, canals, and lodge.

Proof 3 (Structural Subtopic Proof under II):
Subtopics II. A and II. B describe the finished physical lodge: chamber dimensions (with wall insulation and ventilation details) and dual entrance passages.

Level B Diagnostic Evaluation & Scoring Rubric

Tier Level	Component	Points	Mastery Indicator
Tier 1 (I, II)	Main Inquiry Topics	2 Points	Correctly identifies the two guiding questions from Paragraphs 1 & 2.
Tier 2 (A, B, C)	Subtopics	5 Points	Maintains chronological progression (First, Next, Finally) under I, and structural features under II.
Tier 3 (1, 2, 3)	Specific Details	9 Points	Accurately groups concrete construction actions and architectural dimensions under proper subtopics.
