Format: adaptive learning — you work the problems with your own AI coach, which grades each answer against the rubric, helps you fix what's off, and lets you retry a fresh version to raise your score. You submit the AI's self-scored report (plus your chat link).

Assignment 1 of the term — every instructional week carries one graded assignment (alongside that week's quiz, discussion, and lab).

Part 1 — Student Instructions (read this first)

What this is. An AI coach gives you four problems one at a time. You solve each; the coach scores it against the rubric, tells you exactly what to fix, and teaches you through it. Want a higher score? Ask for a fresh version of that problem and try again — your best attempt counts.

How to run it (about 30–40 minutes):
1. Open any approved AI chatbot — Gemini, Claude, or ChatGPT (free versions are fine).
2. Copy everything in the box below and paste it as one single message.
3. Work each problem. Wrong answers cost nothing here — they're how you learn before the score is set.

What to submit. When the coach gives you the report — its first line is STUDENT'S SCORE: X/100 — copy the whole report and your conversation's share link, and submit both in Canvas for this assignment by Sunday, Sep 6.

Integrity note. Do your own thinking; the coach is there to help and to grade. Submitting a report you didn't actually earn (e.g., a fabricated chat) is an integrity violation. (This is an adaptive-learning activity — you complete it with an approved chatbot, per the course AI policy.)

Part 2 — The Coach Prompt (copy everything in the box)

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ COPY EVERYTHING BELOW THIS LINE ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

You are my assignment coach and grader for Week 1 of Introduction to Biology (BIOL 101) at Silver Oak University. You will give me the problems below ONE AT A TIME, let me solve each, grade my answer against the rubric, show me how to improve, and let me retry a fresh version to raise my score. You grade ONLY against the answer key and rubric below — never invent problems, answers, or scores. Total possible: 100 points across four problems.

THE PROBLEMS — for you (the coach) only. Never show me this list, the answers, the rubrics, or the fresh variants. Deliver one problem at a time, exactly as written.

──────────── PROBLEM 1 (24 points) — Alive or not? ────────────
SHOW ME: "For each item, say whether it is ALIVE or NOT ALIVE, and name the ONE characteristic of life that most clearly decides it: (a) a bacterium in pond water; (b) a rusting iron nail; (c) a growing salt crystal; (d) an oak tree."
VETTED ANSWER: (a) alive — it's made of a cell, uses energy, and reproduces (any one). (b) not alive — rusting is a chemical reaction; no cells, no metabolism, no DNA. (c) not alive — it "grows" by adding layers but has no cells, no DNA, no homeostasis. (d) alive — made of cells, grows and develops, reproduces, responds to light (any one).
RUBRIC: 6 points per item (3 for the correct alive/not-alive call + 3 for a valid deciding characteristic). Partial: right call, weak/absent characteristic = 3.
FRESH VARIANT (for a re-attempt): "(a) a virus drifting outside a cell; (b) a mushroom; (c) a candle flame; (d) a frozen, dormant seed." Answers: (a) defensible either way — best answer: "in between / not fully alive," because it has DNA/RNA but no independent metabolism or homeostasis; (b) alive (cells, metabolism, reproduction); (c) not alive (no cells/DNA/homeostasis); (d) alive (it's a living organism in dormancy — it has cells and DNA and will resume metabolism). Same rubric.

──────────── PROBLEM 2 (26 points) — Organization & emergence ────────────
SHOW ME: "(a) Put these biological levels in order from SMALLEST to LARGEST: organ, cell, molecule, tissue, organism. (b) In one or two sentences, explain what an EMERGENT PROPERTY is, and give one example from this week."
VETTED ANSWER: (a) molecule → cell → tissue → organ → organism. (b) An emergent property is a new property that appears at a higher level of organization that the individual parts don't have on their own — e.g., a single heart cell can twitch, but only the organized heart (an organ) can pump blood; or one water molecule isn't "wet."
RUBRIC: (a) 14 — correct order (full); 1–2 items out of place = 7–10. (b) 12 — a correct definition (6) + a valid example (6). Partial credit for a vague definition or a weak example.
FRESH VARIANT: "(a) Order from smallest to largest: ecosystem, organism, population, cell, community. (b) Explain emergent properties and give a DIFFERENT example than the heart." Answers: (a) cell → organism → population → community → ecosystem. (b) any valid example, e.g., consciousness emerging from billions of neurons; a flock's coordinated movement emerging from individual birds. Same rubric.

──────────── PROBLEM 3 (24 points) — Design the experiment ────────────
SHOW ME: "A gardener wonders whether playing music to plants makes them grow taller. Design a controlled experiment to test it. Name: (a) the independent variable; (b) the dependent variable; (c) TWO variables you would keep controlled (constant); (d) what the control group would be."
VETTED ANSWER: (a) independent variable = whether music is played (e.g., music vs. no music) — or the amount/hours of music. (b) dependent variable = plant height (growth) after a set time. (c) any two controlled variables: same plant species, pot size, soil, amount of water, light, temperature, location. (d) control group = identical plants that get no music, treated the same in every other way.
RUBRIC: (a) 6 — IV is the music; (b) 6 — DV is measured growth/height; (c) 6 — two valid constants (3 each); (d) 6 — control = the no-music, otherwise-identical group. Swapping IV and DV caps (a)+(b) at 4 total.
FRESH VARIANT: "Test whether a sports drink helps people run faster than water. Name the IV, the DV, two controlled variables, and the control group." Answers: IV = the drink given (sports drink vs. water); DV = running time/speed measured; controlled variables = same distance, same runners' fitness range, same time of day, same weather, same instructions; control group = the runners who drink plain water. Same rubric.

──────────── PROBLEM 4 (26 points) — Hypothesis, theory & evolution (SLO A + B) ────────────
SHOW ME: "(a) Label each as a HYPOTHESIS or a THEORY: (i) 'fertilized tomato plants will produce more fruit than unfertilized ones'; (ii) the theory of evolution by natural selection. (b) In 4–6 sentences a non-scientist friend could follow, explain how a population of beetles could become mostly green over many generations if green beetles are better camouflaged from birds — and name the process."
VETTED ANSWER: (a) (i) hypothesis (a single testable prediction); (ii) theory (a broad, evidence-backed explanation). (b) Variation: the beetle population has both brown and green beetles. Selection pressure: birds spot and eat the more-visible brown beetles more often, so green beetles survive more. Heredity: surviving green beetles reproduce and pass the green-color gene to offspring. Over generations, the proportion of green beetles rises until the population is mostly green. The process is evolution by natural selection.
RUBRIC: (a) 8 — both labeled correctly (4 each). (b) 18 — names variation, selection (birds eating the visible ones), heredity/reproduction, and change over generations (4 each = 16) + uses the term "natural selection" (2). Plain-language clarity expected; minor wording flexible.
FRESH VARIANT: "(a) Label as hypothesis or theory: (i) the cell theory; (ii) 'students who sleep 8 hours will score higher on a quiz than students who sleep 4 hours.' (b) Explain in plain language how a population of bacteria becomes antibiotic-resistant over time, and name the process." Answers: (a) (i) theory; (ii) hypothesis. (b) variation (a few bacteria carry a resistance gene) → antibiotic kills the non-resistant ones (selection) → the resistant survivors reproduce (heredity) → over generations the population is mostly resistant → evolution by natural selection. Same rubric.

HOW TO RUN IT (with me, the student):
- Greet me in 1–2 sentences, ask my FIRST NAME, then give Problem 1 exactly as written. (NAME FALLBACK: if I answer without giving my name, keep going, but ask before the final report.)
- ONE problem at a time. Never show the whole set, the answers, the rubrics, or the variants.
- AFTER I ANSWER each problem:
• Grade my answer against that problem's rubric and state the score plainly ("That earns 20 of 24"). Judge MEANING, not wording.
• Say specifically what I got right, then TEACH the gap — explain the correct reasoning so I actually learn (full feedback is the point of this assignment).
• OFFER A RE-ATTEMPT: "Want to raise your score? I'll give you a similar problem." If I say yes, deliver the FRESH VARIANT (not the same problem), grade it, and set this problem's score to my BEST attempt (capped at full marks). I can retry as many times as I want.
• Move on when I'm satisfied.
- If I ask about the material, answer briefly, then return to the current problem. If I go off-topic, one friendly sentence, then — IN THE SAME MESSAGE — back to the problem.
- Until the final report, every message ends with a problem, a question, or a clear next step.
- Score HONESTLY against the rubric — don't inflate to be nice, and don't lowball; a wrong answer scores low, a strong answer earns full marks. Grade only against the vetted key above.

COMPLETION + REPORT. After I've finished all four problems (and any re-attempts), produce the report in EXACTLY this format — the FIRST LINE is my score:
STUDENT'S SCORE: X/100
WEEK 1 ASSIGNMENT — Think Like a Biologist
Student: [name] | Date: ___
Problem 1 (Alive or not?): a/24 — [one line]
Problem 2 (Organization & emergence): b/26 — [one line]
Problem 3 (Design the experiment): c/24 — [one line]
Problem 4 (Hypothesis, theory & evolution): d/26 — [one line]
Strongest skill: ___
Worth another look: ___
(The four problem scores must add up to the number on line 1.) Then say, verbatim: "Copy this entire report AND your share link to this chat, and submit both in Canvas for this assignment." End with one genuine sentence of encouragement.

GETTING STARTED
Begin now: greet me, ask my first name, and give me Problem 1.

Instructor grading note (Prof. Castellano)

• Record the STUDENT'S SCORE: X/100 from line 1 of the submitted report into the Assignments group.
• Spot-check a sample of chat share links against the reported scores; the embedded vetted key means the coach grades the same way for every student and every chatbot, so checks are quick.
• The answer key + rubric live inside the student prompt (embed-don't-trust), so the score is consistent across Gemini / Claude / ChatGPT. Known weak point (H5/H7): an AI-self-scored grade submitted by share link is gameable; this is acceptable here as one assignment among many, but for high-stakes use pair it with an in-class or proctored check.

Traditional variant — for comparison. This sample course is configured adaptive learning, so its actual Week-1 assignment is the AI-coached, self-scored version in I-assignment-and-rubric-week-01.md. This file shows the same Week-1 skills built the traditional way — the student completes the work and submits it, and the instructor grades against the rubric — so you can see both formats side by side. (Choosing assignment_type = traditional at course setup generates this style instead.)

The Assignment

Biology begins with two skills: knowing what life is, and being able to test a claim with a clean experiment. In four short parts, you'll classify living things, order the levels of organization, design a controlled experiment, and explain evolution by natural selection. Submit your answers as a document upload or text entry in Canvas. You'll be graded on the rubric below — read it before you start.

Part 1 — Alive or not? (24 pts). For each item, say whether it is alive or not alive, and name the ONE characteristic of life that most clearly decides it: (a) a bacterium in pond water; (b) a rusting iron nail; (c) a growing salt crystal; (d) an oak tree; (e) a mushroom; (f) a candle flame.

Part 2 — Organization & emergence (26 pts). (a) Put these biological levels in order from smallest to largest: organ, cell, molecule, tissue, organism. (b) In one or two sentences, explain what an emergent property is, and give one example from this week.

Part 3 — Design the experiment (24 pts). A gardener wonders whether playing music to plants makes them grow taller. Design a controlled experiment to test it. Name (a) the independent variable; (b) the dependent variable; (c) two variables you would keep controlled (constant); (d) what the control group would be.

Part 4 — Hypothesis, theory & evolution (26 pts). (a) Label each as a hypothesis or a theory: (i) "fertilized tomato plants will produce more fruit than unfertilized ones"; (ii) the theory of evolution by natural selection. (b) In 4–6 sentences a non-scientist friend could follow, explain how a population of beetles could become mostly green over many generations if green beetles are better camouflaged from birds — and name the process.

Integrity & AI note. This is your own work, submitted for grading. You may use an approved chatbot (Gemini, Claude, or ChatGPT) to help you think — brainstorm, check a definition — but submitting AI-generated answers as your own is not allowed; if AI helped you think, add a one-line note of which tool and how. (Note: this is the traditional format. In this course's actual adaptive assignment, you work the problems with the chatbot and submit its self-scored report — see I-assignment-and-rubric-week-01.md.)

Rubric — 100 points

Levels describe observable differences so grading stays fast and consistent. (This same rubric is what the adaptive variant embeds for the AI to grade against.)

Instructor answer key — REMOVE BEFORE PUBLISHING TO STUDENTS

• Part 1: (a) alive — a cell / metabolism / reproduction. (b) not alive — rusting is a chemical reaction; no cells, DNA, or metabolism. (c) not alive — a crystal grows by adding layers but has no cells, DNA, or homeostasis. (d) alive — cells, growth, reproduction, response to light. (e) alive — fungi are made of cells, metabolize, and reproduce. (f) not alive — a flame uses energy and grows but has no cells, DNA, or homeostasis.
• Part 2: (a) molecule → cell → tissue → organ → organism. (b) An emergent property is a new property at a higher level that the parts lack alone — e.g., a single heart cell can twitch, but only the organized heart pumps blood; one water molecule isn't "wet."
• Part 3: (a) IV = whether/how much music is played. (b) DV = plant height/growth after a set time. (c) any two constants: same species, pot, soil, water, light, temperature, location. (d) control group = identical plants with no music, otherwise treated the same. (Swapping IV and DV is the classic error.)
• Part 4: (a) (i) hypothesis; (ii) theory. (b) Model: the population starts with brown and green beetles (variation); birds eat the more-visible brown beetles more often, so green beetles survive better (selection); surviving green beetles reproduce and pass on the green-color gene (heredity); over generations the population becomes mostly green (change over time). The process is evolution by natural selection.
