🔎 Investigation question
Explore how a reflector changes warming in the same sunlight.
Two boxes sit in sunlight. One has a shiny reflector directing light inward, while the other has none. The reflected-light box warms more quickly.
Challenge 1 · Predict
Which box is predicted to warm more in this model?
🧪 Experiment station
Choose a setup and run the model
Box without a reflector
📋 Lab observations
Make a prediction, then run this setup to observe the outcome.
Comparison bars show illustrative relative results, not live laboratory measurements.
Challenge 2 · Explain with evidence
Which observation is the best evidence?
Run both setups to unlock this evidence challenge.

The numbers are illustrative, not a prediction of every outdoor test.
Science Lab practice is formative: it does not award stars or mark a lesson complete. Graded questions follow below.
