G G G...Ghost!

Today we learned about the letter/sound 'g'. Cara put vinegar in a bottle and then attached a balloon filled with baking soda over the neck of the bottle. When the vinegar and baking soda mixed it caused a chemical reaction and carbon dioxide gas was produced. This caused the balloon to inflate. The balloon looked like a scary ghost! After our experiment, we drew diagrams and wrote about the balloon ghost in our writing books.

Before completing the experiment, lots of the children predicted that the balloon would explode and Shanaya thought we would have to spend the rest of the day cleaning up the classroom! Although the reaction was exciting, luckily it wasn't quite that dramatic! What fun we have at writing time.
