By day 10, the results were surprising. The beans in the dark (Pot D) actually grew the tallest at first, but they were pale, thin, and weak—a process called etiolation . The beans under the "pink" light were shorter but had the thickest stems and darkest green leaves. 5. The Conclusion

For 14 days, he measured the height of the sprouts every morning with a ruler and took photos. This is the of the work. 4. The Discovery (Data Analysis) issledovatelskaia rabota po biologii 7 klass

He guessed that natural sunlight would be best, but wondered if "pink" phytolamps (blue + red light) would actually beat the sun. 3. The Laboratory (The Experiment) By day 10, the results were surprising

Total darkness (to see what happens when photosynthesis fails). The Blueprint (Hypothesis and Goal)

Maxim set up four identical pots with the same soil and the same amount of water: Natural windowsill light (Control). Pot B: Constant LED white light. Pot C: Red light only.
