Fizzy, Bubbly Science!

For the past week we have been
exploring "Changes in Matter." We have learned that there are two different types of changes in matter: physical and chemical. We have learned that physical changes in matter are changes that make matter look different without becoming a new substance. Chemical changes in matter are changes that cause one kind of matter to become a different kind of matter. Today we conducted a lab with the focus questions of "What, if anything, will happen if you combine baking soda and vinegar?" Students made their predictions and then they were off to conduct their experiments. Students found that when the two different substances were combined, baking soda and vinegar, that a very fizzy and bubbly reaction occurred. Together the two substances reacted to produce carbon dioxide. Based on the new matter that was formed, gas, the students were able to successfully conclude that this was an example of a chemical change in matter. Our final experiment for "Changes in Matter" will come tomorrow and it is sure to be a BLAST! (Hint, Hint!) Stay tuned...
