5. Explore ingredients; notice how everything
around us is made up of chemicals consisting of atoms bound together into
molecules. But what about companies that claim their products are chemical
free, how can this be?
o
When exploring ingredients you really do see how
we are surrounded by a lot of things that are made up of chemicals. I think
that the companies claim their products chemical free because they want their
product to sell, but also because they might be talking about how there is no
harmful chemicals in their products.
I really like the materials you used to make your models. They look very nice and I like that they are actually able to stand on their own instead of just laying on the table. Also great job on finding the chemicals for number 2. Quite a few of yours were the same chemicals that I decided to use for my post as well. I really like the pictures you chose for each one of your chemicals. Great job formatting your post and keeping it easy to read.
ReplyDeleteI also like the materials you chose for your models and the fact that they stood up on their own. I used marshmallows and toothpicks and it was a bit unsturdy. When I have to make molecule models again in the future I will use playdough/clay like you have. Thank you! The "Green Aussie cleaner" was a tough question to wrap my head around, I really had to dig deep to figure out that situation. I agree with what you say but there really isn't an answer to this mystery because "chemical free" is not possible.
