Mrs. Valerie Riley’s biology class has learned about Hypertonic, Isotonic and Hypotonic solutions. To see the solutions in action, the class completes a lab using an egg that had been placed in water, vinegar and syrup.

If the solution is hypertonic, the solution will move outside the egg. If the solution is hypotonic, the solution will move to the inside of the egg. If the solution is isotonic, the solution will move both in and out of the egg at the same time.

To get an even better idea of what type of solution syrup was, the students weighed the egg after 24 hours of soaking it in the syrup and decided that syrup is a hypertonic solution.

“I got a better understanding of hypertonic, isotonic and hypotonic solutions,” said Jennings Codd, Class of 2019. “Also, I learned that eggs are disgusting.”
