iTunesU Science and Cooking = Chemistry

Chemistry
Why does oil float on water? Why does an apple turn brown once you break the skin? these a few questions students have when we ask them to wonder, make observations, and question the world as they see it. When I budget for my science class I always add about $2-$300 dollars just for the grocery store. Why? That is where I find most of the chemical I need to teach chemistry. I would use //Science and Cooking// to help students understand chemistry terms, how chemistry is all around us, and how they can apply what they already know, background knowledge, to a new, or higher level concept.

Students will find it interesting, and possibly remember a concept or vocabulary term, when they can relate something they already know,(background knowledge) such as food turning brown, to science. One of the first videos I found relates to chemical change through oxidation. The process is a chemical change the term is oxidation. These are not tough terms but in a video lab with an apple and a gourmet chef? It's great material.

Then we can proceed to apply the students' knowledge. They can try to relate other items, starting with food that oxidizes (chemical change) and hopefully apply that knowledge to the real world. For example, after I take down a picture from the bulletin board, I can ask, "Why did the paper change color?" If they can say chemical change or oxidation, than I know they have mastered the vocabulary terms.

Then have gone from, "Why to apple turn brown?" to, "An apple turn brown when the fruit has been exposed to air, oxygen, and causes a chemical reaction." The chemicals and enzymes in the fruit and oxygen causes it to break down more quickly. Finally we can then discuss how to stop the apple from oxidizing. Maye they have seen their parents put apples in water or lemon juice and it doesn't turn brown andthen they see it on iTunesU! It's all about making connections.

This will be great for chemistry!
