Instructions
A generative AI image tool only knows what your prompt tells it. In this project you will create the same subject twice: once with a vague prompt and once with a detailed prompt that adds style, lighting, mood, and setting. Then you will compare the two images side by side and explain which prompt elements changed the output.
Deliverables
- Image A: generated from your vague prompt.
- Image B: generated from your detailed prompt (same subject).
- Written explanation: what each prompt element changed, plus a short reflection.
- PDF submission: the page builds it for you with your name, period, times, prompts, both images side by side, your writing, and your score.
Example
How this works
- Enter your first name, last name initial, and class period, then click Start Assignment. Your start date and time are recorded.
- Pick one subject. Write a short, vague prompt (8 words or fewer) and generate Image A in the AI image tool your teacher assigns. Download it and upload it to this page.
- Write a detailed prompt for the same subject (at least 20 words). Include a style, lighting, mood, and setting. Generate Image B, download it, and upload it.
- Copy the exact words you used for each element into the matching boxes. The page checks that those words are really in your detailed prompt.
- Look at the side-by-side comparison. For each element, explain what it changed in Image B compared with Image A. Then finish the reflection.
- Watch the Rubric Tracker on the right. It updates as you work so you know exactly where your points come from.
- Click Submit for Score, then Download PDF Submission and turn it in the way your teacher tells you.
Image rules
- Keep every image school appropriate.
- Do not generate images of real people (classmates, teachers, celebrities) or copyrighted characters.
- Upload PNG, JPG, WEBP, or GIF files up to 10 MB. Both images must come from your own prompts.
Grading rubric (20 points)
The page scores each item below automatically. Your teacher reviews your PDF and may adjust points if an image does not match its prompt or the writing is off topic, copied, or filler.
| Criterion | Full credit looks like | What the page checks | Points |
|---|---|---|---|
| A. Vague prompt | A short, simple prompt that names only the subject. |
|
2 |
| B. Detailed prompt | The same subject, described in rich detail with all four elements clearly stated. |
|
4 |
| C. Images | Two clear AI-generated images, one from each prompt. |
|
4 |
| D. Element explanations | For each element, a specific description of what changed between Image A and Image B and why. |
|
8 |
| E. Reflection | Names the element with the biggest effect, explains why, and says what you would change in a third prompt. |

Student Information
Step 1Choose your subject
Pick one thing to generate both times, such as a dog, a city, a robot, or a sneaker.
Step 2Image A: the vague prompt
A 2 pts · C 2 ptsKeep it short. Name the subject and nothing else. Generate the image, download it, then upload it here.
Step 3Image B: the detailed prompt
B 4 pts · C 2 ptsSame subject, much more detail. Include a style, lighting, mood, and setting. Aim for at least 20 words.
Copy the exact words from your detailed prompt that set each element. Each one must appear in your prompt and be different from the others.
Step 4Compare side by side
Study both images. Look at colors, brightness, background, art style, and how each image makes you feel.
Step 5Explain what each element changed
D 8 ptsFor each element: what words did you add, and what is different in Image B compared with Image A because of them? Be specific (colors, shadows, background, art style, feeling).
