Section 04 — Observing the Natural World
Course: LBS 120 – Physics with Lab
Session Overview
Observation is the foundation of physics. Today, you’ll explore how attentive watching—without assumptions—can reveal motion, patterns, and questions that diagrams and equations can’t fully express. This session focuses on observing reality directly and letting your curiosity lead.
Learning Objectives
By the end of this session, you will:
- Appreciate observation as a scientific method before explanation
- Recognize how preconceptions can distort perception
- Capture movement through sketch, measurement, and attentive notes
- Reflect on how slowing down your gaze alters understanding
Session Flow
1. Set Intention
Begin by slowing your breath and opening your senses. Choose a motion—swaying trees, water dripping, someone pacing—and let your eyes follow it, silently. Notice how doing nothing else opens your mind.

5. Observe
Find a simple motion in your world—pouring water, swinging pendulum, walking steps. Don’t explain it. Just observe. Describe it in words: the pace, rhythm, irregularities. Let your senses do the measuring.
Key Quote Box

Practice Blocks
Simply Motion Experiment
Drop two objects (like a pen and eraser) from the same height. Observe, record, and sketch what happens. Note any surprise—sound, bounce, timing, or alignment—and what questions emerge.
Shadow Tracking
Over two hours, mark the position of a shadow every 15 minutes. Use quick sketches. What does the shadow reveal—about light, movement, time, or your place in the world?
Reflection
Write a short response: - How did slowing down and observing change what you noticed? - What assumptions fell away when you didn’t rush to explain?
Optional Hard Problem
Observe a pendulum or swing at different lengths or speeds. Sketch or photograph different points of motion (e.g., peak, mid-swing). Reflect: What patterns emerge? Which points feel most expressive or “true”?
Notes
- This session is intentionally slow—don’t rush observation.
- If you feel tempted to explain, pause. Ask “what do I actually see?” before theorizing.
- This is practice for patient perception—foundational for all scientific and creative work.
