Last week the 1st Grader was given a science project assignment to make a fossil egg of a pterosaur. Now, the thing about me overseeing science projects is that I’m not really a science person. I can do math all day. I love art. I even enjoy English. But, I just don’t get excited about science. First of all, I can’t pronounce the words. Pterosaur? There’s just no need for the silent “p”on the front of that word, is there?
And, that’s why the Spouse, with his chemistry background and all, is typically the overseer of all things science-related. But, this project was going to require more time and really needed to be done during the day. So… I had to rise to the occasion.
Sounding simple enough, the project started with a hard-boiled egg.
The 1st Grader was supposed to barely crack her egg and make an imprint of the cracked shell on the play-doh. But, of course, everyone had to have an egg and participate.
Not surprisingly, this is what the Preschooler’s egg situation looked like five minutes later. You can imagine the aroma.
The next part in the process is where our project derailed. When I re-read the instructions I noticed we were lacking one all-important supply for our second {and most important step} of the fossil egg: plaster of Paris. No need to worry, I thought. We’re close to a Jo-Ann’s. But, would you believe that I called our local Jo-Ann’s only to discover they were sold out of plaster of Paris?! How can a craft store be out of plaster of Paris?? This is like Home Depot selling out of lumber. It just shouldn’t happen. Ever. And most certainly not the afternoon/evening before I have to make a fossil egg.
Unaware of the potential for such a disappointing outcome, we coated our play-doh in the homemade plaster and cleaned up the HUGE aftermath of the project.
Then, we set the egg on a plate in anticipation of it drying so we could do the final step of the project: staining the plaster with tea to make it look aged {like a fossil, of course}.
We checked at 7:00. Then at 8:00. And, again at 9:00. Still not dry. So, we went to bed hoping we could wrap it up the next morning. Only, the next morning, some 14 hours after we put the Google version of plaster on this thing, our plaster still had yet to harden.
{This picture was taken during happier times when we thought the fossil was well on its way to completion}.
So, I did what any tired mom would do. I bagged the project up in a Ziploc and sent this little mess of a science experiment in with the 1st Grader with the sad explanation that our fossil egg had not yet fossilized. And, that was as good as we could do.
Blame it on Jo-Ann’s.
I think we she should get an “A” for effort.
And, I also think plaster of Paris, at least the homemade variety, should be renamed plaster of Problems. Or, maybe just plaster of Potential. Because it might potentially harden… and it might just not.

Wow, compared to some of the projects we've turned in through the years, yours is AWESOME! I would have been substituting and re-writing the experiment way back at "hard boiled egg." Thankfully the grading curve is usually pretty generous 🙂

Thanks for the encouragement, Tisha! I think I'll follow your lead and tweak the experiment a bit next time 🙂
