Volcano Experiment!

25 Sep

Today, we completed the volcano experiment from the Expedition Earth curriculum by Erica (a.k.a. Confessions of a Homeschooler).  If you’re interested in the supplies list and details for the experiment, I suggest contacting Erica; or better yet purchase her geography curriculum, Expedition Earth!  It costs $15 (all downloadable files) and is chock full of activities for countries around the globe.  Erica also offers an animal supplement, Expedition Earth Animals.

Daddy helped our oldest daughter mix the ingredients for the cone of the volcano.  I loved that the recipe required everyday “pantry” ingredients such as flour, salt, oil and water.  No extra trips to the grocery store!

Admittedly, I bought the wrong-sized plastic soda bottle.  We don’t generally drink soda and I realized too late that a two-liter bottle may be overkill.  Nonetheless, we proceeded with the experiment and colored the water red  for the lava effect!

Here the girls are building the base or cone of the volcano.  We ran out of mixture but it didn’t lessen the excitement.

Adding a key ingredient – baking soda.  Steady hand, Daddy!

The second key ingredient – vinegar!
