Notes on Scientific Experiments and Diagrams

Experiment Observations

Yadu's Experiment:
- Test Tubes: A (boiled rice) and B (chewed boiled rice) were used to test the presence of starch using iodine solution.
- Expected Results:
  - Test Tube A: Initial color before iodine - [to be filled].
  - Test Tube B: Initial color before iodine - [to be filled].
  - Final color after adding iodine - [to be filled].
  - Possible reason for color change - [to be filled].
Rakshita's Experiment:
- Test Tubes: A (inhaled air) and B (exhaled air) passed through lime water to observe reactions.
- Expected Results:
  - Test Tube A: [to be filled].
  - Test Tube B: [to be filled].
