1. Great job exploring a very interesting science idea about making plastic from milk. I like that you asked a strong scientific question. In future projects, try adding more information about your steps, results, and what you discovered so others can fully understand your experiment. Keep up the great scientific curiosity!

2. Great job investigating how acidity affects milk plastic. I liked that you included a hypothesis, identified variables, and reflected on what could be improved. Your results and discussion showed thoughtful scientific thinking. Keep exploring real-world science questions.

3. Very interesting and unique project! I did not know that milk could be turned into plastic! I hope you can dive deeper into this in the future!!

4. This is such an impressive and creative chemistry project! 🧪🥛 Comparing vinegar and lemon juice was a smart choice, especially since you included information about their pH levels to support your thinking.

   I really like how you carefully observed the differences, not just when the curds first formed, but also after the plastic dried. Noticing that vinegar created firmer curds at first, while the lemon-based plastic became harder once dry, shows strong attention to detail and excellent scientific observation skills.

   You clearly understand how acids can change the pH of milk and cause casein to form a solid material. That’s real chemistry in action! Keep asking big questions and testing them. You’re thinking like a true scientist and engineer.

5. Very interesting project. Great work!

6. Such an interesting topic. Thoughtful research. What a promising young scientist!
