Original Prompt## ay 1: Launch Phenomenon & Observation vs. Inference
**Learning Objective:**\
\
Students will be able to distinguish observations from inferences and begin developing a model to explain what happens in a sealed terrarium over time.
**45-Minute Timeline:**
* **0:00–5:00 | Opening/Hook**
* Teacher says: "Today we're starting with a mystery. Look at this sealed terrarium in front of the class. I sealed it three weeks ago and haven't added any water or food. Yet it's still here, still green,...
This learning resource focuses on the concept of observation versus inference in scientific investigation. It begins with an engaging hook, the 'Sealed Terrarium Mystery,' designed to spark curiosity about how a mini-ecosystem can thrive indefinitely without external water. The agenda outlines a structured 45-minute lesson plan that includes defining observations, identifying inferences, and conducting a data collection lab. Students will explore qualitative and quantitative observations and learn to formulate logical inferences based on evidence. Throughout the lesson, students will engage in activities such as classifying statements as observations or inferences, participating in group discussions, and completing reflective tasks that apply their learning in real-world contexts. The resource emphasizes hands-on learning, critical thinking, and the scientific method, culminating in a preview of upcoming explorations into the water cycle.
