Mt. Vesuvius Exploded! (Not!)
We studied volcanoes this week as we read about Pompeii... Buried Alive in Reading. As a culminating project, we wanted to do an experiment to show how a volcano erupts! It was not as awe-inspiring as we hoped, but we had fun! :)
First, we measured the baking soda and put it in the cone.
Next, we mixed vinegar, dish soap, and food coloring for the effect!
Last, we poured the vinegar, soap, and food coloring mixture into the baking soda in the volcano.
Then... it erupted... sort of! The chemical reaction didn't work well! I guess the lesson is that sometimes experiments don't work out!
Okay... we have to try it again!
Well... hmm... There's always other experiments!

Our Salt Dough Maps and the Recipe!
Salt dough recipe:
4 cups flour
2 cups salt
2 cups water
2 tablespoons cream of tartar
Mix with your hands (that's the fun part!) until it's the consistency of play doh. Add more flour or water as necessary.
First, we started with a map of the United States.
Then, we mixed and measured flour, salt, cream of tartar, and water to make a salt dough.
Then, we mixed in the water and kneaded the dough by hand.
Then, we used a physical map to see where the various landforms we studied were located.
Next, we covered our United States map with the salt dough.
Then, it was time to make the mountains, plains, rivers, and lakes.
Our salt dough maps are completed.
We let the salt dough dry overnight.
The next day it was time to paint the map and landforms!
What a fun, educational project!!
