Keeping Water Balance Both Inside and Outside Your Body

February 16, 2018 Adrienne Brown 0 Comments

My 7th-grade daughter conducted an experiment that helped her to see how our bodies had the ability to maintain water balance in and outside of itself,  by using an egg.

Yeah, I found it kind of weird at first, until I saw the bubbles coming up from the vinegar solution.

Using the egg we observed how the water level balanced out when the egg was exposed to various liquid environments. Like vinegar and thick corn syrup.

First of all, it was amazing to see after 3 days, the surrounding egg shell had dissolved into thin air! While the egg remained intact, because of a thin membrane.practicalminedness-osmosis 1

It became a clear see-through egg!

The vinegar ate the shell, which is (calcium carbonate) clean away!

Meanwhile, the water from the vinegar sneaked into the egg!practicalminedness-osmosis 2

Can you believe it! It’s called “OSMOSIS” (when water seeps through from one place to another)

Sorta like when your camping and your sleeping bag somehow becomes wet, that’s that OSMOSIS working!

Then she put it in some thick corn syrup, this caused another OSMOSIS reaction.practicalminedness-osmosis 5 After 1 day, again the water seeped through the thin egg membrane into the corn syrup!practicalminedness-osmosis 4

This was a cool Abeka Books, experiment!

Remember, although it was for my 7th grader, my entire homeschooling family got a chance to OBSERVE!

That’s the beauty of homeschooling!
