MR. WEILER’S SCIENCE LAB
FINAL EXAM STUDY GUIDE — UNITS 1–3

This ZIP contains 25 MP4 videos, numbered Q01–Q25 to match the Terms 1 & 2 study guide.

HOW TO USE
1. Extract/unzip this folder.
2. Open the video whose number matches your study-guide question.
3. Pause and replay to inspect the models and read the captions.
4. Use your science journal and STEMscopedia to write your response.

These are video exports with preset trials, not interactive files. Models are simplified and not drawn to scale. Some questions contain several model views. No density-equation calculations are required. Lab ambience and matching sound effects are included; there is no spoken narration.
