Rainy day.....science

In the lab today, we are making crystals....

Testing for air pollution....

And, dissolving capsules..





The crystals will take up to 5 days to grow, and there were chemicals involved so O got to wear goggles and gloves. The air pollution test simply involves a piece of poster board, and 6 -7 metal lids. Each day we will go out, and remove a lid, and then compare the debris that has been collected around each label to determine our air quality. And then, of course those creepy pill looking things that magically turn into a sponge are fun to watch, too.

You know what is really gross? It's when the water from those disolved capsules ends up all over your floor. Ohhhhhh so slippery.
