Jurassic Volcano

For dinosaur week we made and erupted our very own volcano! We read in the book Dinosaurs that lots of volcanic eruptions may have led to the dinosaurs becoming extinct so Tommy wanted to see if he could "erupt" his own dinosaurs.

The recipe for the dough was very simple (that's the way we roll around here):

6 C. Flour

2 C. Salt

4 Tb. Oil

2 C. Water

Mix together and shape a volcano around an empty plastic bottle.

I like to set up my science experiments at the table the night before we do them. The purpose of this is two-fold: first, I'm sure to have everything ready so that we actually do it; second, it's kind of like an "invitation" that piques the interest of my little guy so that he is begging me to make the volcano and erupt it. I LOVE IT!

My "Invitation"

I know there are other recipes out there. We could have let our volcano sit to dry overnight and then paint it, but my little boy just wanted to get to the fun stuff: explosions!

We used the recipe for the Foaming Monster experiment from 50 Science Things to Make and Do to make our "lava". It's just vinegar, a squirt of dish soap, some food coloring if you want it (we chose blue lava this time), and then add the baking soda. If you put the baking soda on a little square of toilet paper, crumple it up, and then throw it into the bottle it takes a few extra seconds for the eruption to start. By the end I just let Tommy add more vinegar and baking soda directly to his heart's content. I think he made 4 or 5 eruptions total, which was awesome. Check it out. Also, at the end of this video is a clip of my baby making dinosaur noises, which is adorable.
