While we've clearly figured out what is causing the bath bomb reaction, we were curious still about all the remaining ingredients in bath bombs and the reasons behind their inclusion in various recipes. We were wondering about all the oils, starches, scents, and even alcohol! What do they do if they're included in a bath bomb but not necessary to make the new substance? We read an article to help us better understand ingredients! These other ingredients are used to moisturize our skin, keep the bath bomb together and hard so it doesn't collapse, and even relax us! |
We also are wondering how the odors in bath bombs work. Like what are they? How do they reach our nose? We explored various scents, trying to guess them along with analyzing their molecular structure!
We are starting to see some patterns, and with some further research, we came to the following agreements:
1. Odors are evaporated molecules that reach our nose, and receptors interpret the molecules with our brain's help!
2. Every odor is a different molecule, so odor must be a property.
3. All odors are comprised of different amounts of arrangements of carbon, hydrogen, and oxygen.
4. If one atom from an odor molecule is dropped or added, we end up with a new molecule, and therefore a different substance and odor. That explains why perfectly cooked popcorn smells different than burnt popcorn!
Next steps, return to our DQB to answer all the questions we set out to ask when we launched our unit!
