"This project seeks to determine why there are so many salts and what makes them different? In our world there are many different salts, few understand the differences between them all, some are used for food and consumption, others are used for cleaning, health and medical uses. Why are there so many salts and what makes them different? Most are used for cooking and contain at least NaCl( sodium Chloride) or some are K (Potassium) based formulas. That would be your typical cooking salts. Table, Sea, Kosher, Pink and Light salts. However the Epsom Salt is made up of MG (magnesium) and doesn't taste good at all, however is great for reducing inflammation. To see what your salt is made up of all you need to do is gather all materials ,create samples with 1 pin stub and add carbon tape to the head and rub the gold bar to discharge any electrons on the sample.. Dip tape covered pin head into sample 1 of salt. Place the pin head into the carrier. Repeat for each salt samples. Create graphic of sample layout to use s reference as your looking at each sample. Observe each salt sample under the microscope. Take pictures of each for analysis. Run chemical analysis. Record your observations. Touch, taste, and observe differences of each sample and record observations. Every salt looks, tastes and feels different. Not all are just for cooking. You can see that under an electron microscope. #chemistry #salt #womeninstem #stem #earth #food #foodscience #lab #smaple"

  1. Great job, Harper! Super interesting, as I’ve always wondered what the difference was between all the various salts.

  2. I loved reading through your experiment and data! Very nice images and collaboration to get them. And that is so wonderful you thanked all the people that you thanked for their help!

  3. Very interesting idea. I’ve often wondered what the differences in salts are myself. Good information.
