Chalky Rocks

I just love easy science experiments that are entertaining and cheap!!!!

We are presently studying about rocks and minerals. We live in the perfect place for that!


Anyway, the kids were supposed to find rocks and test to see if they contained chalk. All you have to do is drip vinegar onto the rock and wait to see if it fizzes. EASY and not very messy at all!

With cheeks full of gummies and a dropper filled with vinegar, Lincoln was ready to be a geologist!! He tested a bunch of rocks from his rock collection that he's been building up for the past few years now. Not a one was a chalky rock. But a few days later big brother finally found one and they were so excited. Mullin drew a picture on our back patio with it. Oh, I should have taken a photo. :(

We are planning a summer field trip to expand our rocky horizons. So stay tuned!

Booger Bandits

We did another "Disgusting Science" project today.

Boogers are great as long as they don't end up on the wall! The boys learned that we need mucus to keep dust and other junk from clogging up our lungs. Hopefully they will still understand the importance of cleaning out their noses before going out in public!!!

Mullin did not want to pose with a "booger", so Lincoln gladly took the opportunity!

Think Before You Touch

Prepare to be sicked out!!Mullin bought a Disgusting Science kit with his birthday $, and this is his first experiment.
We prepared petri dishes and took samples from various places. Then we watched what grew for about 12 days. Do you really want to know where the samples came from??

From left to right: bathroom sink, inside of mouth, coin, bottom of a shoe

The money and bottom of shoe started growing nasty stuff almost immediately! Nice to know that my cleaning efforts haven't gone completely to waste.

Hopefully my family can appreciate and respect our "no shoes on in the house" rule a little more after seeing this!! (Well, you can only wear "inside" shoes--it is a must on all tile floors)

I had thought of taking samples from a library book and Shiloh's passy but didn't think I would be able to bear the results. What you don't know can't hurt ya, right?
