Science Fun

Here are a few random science experiments the kids and I have done recently:

Most of these are from sciencebob.com and this one is called Fantastic Foamy Fountain:


We added water and yeast to hydrogen peroxide and dish soap...

...and immediately we got a reaction!

So fun!



This one is called Lava in a Cup:

We added oil to colored water

...and of course it sat on top

Then we poured salt in...
(It's hard to see here, but the salt, which was heavier than either the water or the oil, sank to the bottom, carrying some oil with it.  When the salt dissolved, the blobs of oil would float back to the surface, looking a bit like a lava lamp)

Cleaning Pennies with Vinegar:

We got some dirty pennies...

Added them to vinegar and salt...

..the acid in the vinegar reacted with the salt to remove the copper oxide on the pennies!

This one we saw on Facebook and it's called Climbing Water:

We filled six cups half full with water in the colors of the rainbow...

Next, we put a paper towel "bridge" between each of the cups...

After a while, the water had "climbed" up the paper towels and started to mix with it's neighboring color!

That's all for now - maybe next time we'll blow something up... =)

Science... SO not my area of expertise... I'm thankful often that I have my prep while the kids so to Science...

However, I do love seeing the excitement and wonder on your kids' faces as they watch the experiments. So sweet :)

Looks like you are all having fun and keeping busy!

Miss you!
