Volcano in Our Classroom

Ms James brought in some vinegar, baking soda, pink food colouring and a "volcano" structure. Her assistant, helped her to put in the "ingredients" into the volcano. 

Can you guess what happened when he poured in the vinegar? Yes, the volcano exploded with over flowing pink lava.

We created a few other explosions.

Can you see the lava bubbling?

Later, we recorded our experiment. What happened before and after.
