Volcanoes Erupt in Preschool Pals!
We learn that deep, deep, deep beneath the ground is hot melted rock, called magma. Sometimes red hot magma can burst up in a volcano mountain from cracks in the earth. Lava is the hot magma flowing down the volcano mountain.
Three and four year olds love to play make believe and can learn a lot of fun facts in the process. After learning about volcanoes, we made one with a few household supplies: baking soda, water and soap, red coloring, vinegar, cup and foil and a plate to catch the mess.
Baking Soda Mixture
Mix together in the small cup:
3 Tablespoons Baking Soda
Pinch of red paint or food coloring
3 or 4 Tablespoons Water with a few drops of dishwashing soap
Make Volcano Mountain:
Tin foil (clay with sticks and other earth features make it even more realistic)
Plate or pan to catch the flowing “lava”
Create a mountain of foil over the cup with the baking soda mixture. Poke a hole in the top of the mountain so that you can add the final ingredient- Vinegar.
Start the lava flowing:
Add sound effects: "Rumble", "hissssss", "Crack"
Pour about 1/2 C vinegar through the small hole and watch the lava flow.
To extend the experience further check out an excellent book about volcanoes for beginners called,
Jump Into Science: Volcano! By Ellen j. Prager.
