My project tested which medicine pills dissolved fastest in hydrochloric acid (stomach acid). I chose this project so that I would know what type of pills to take in the future when I start feeling sick or have a headache. The faster the pills dissolve, the faster I should feel better. The hard tablet pill and the soft tablet pill both dissolved the fastest out of all the pills, at about 6 minutes. The chewable tablet took the second longest at 68 minutes, and the chewable gummy took the longest and never fully dissolved. My project can show others what types of pills to take so they can feel better quicker.

This is a great project that explores how medicine dissolves in stomach acid. I really liked how you simulated stomach acid and tested different types of pills. Your data clearly showed that hard and soft tablets dissolve much faster than gummies. You might also control variables like temperature or stirring to make the experiment even more scientific. Excellent work exploring chemistry and medicine!
This project is a fantastic example of ‘science you can use’! I was very impressed by your ability to create a simulated stomach environment using hydrochloric acid to test your hypothesis. Your data was clear, and I appreciated your scientific integrity you were honest about the chewable gummy not dissolving, which is a valuable scientific observation! You successfully identified that hard and soft tablets dissolve the fastest, providing a practical takeaway for anyone looking for quicker relief. For future research, you might consider how the stomach’s movement (mechanical digestion) would interact with the chemical breakdown you tested here. Excellent work!
