Bottle Village Cake

Yesterday was Joanne’s birthday. She is my mom’s best friend and also the president of the non-profit organization, Preserve Bottle Village. There is a board meeting tomorrow that I am going to and another member, Drew, and I were talking about baking a cake for Joanne. I emailed her a great idea for a crazy cake that I thought Joanne would get a kick out of but Drew hated it (LOL) and ordered a cake from a store that is a ‘photo cake’. Drew told me that she picked one of my photographs to be on the cake (WOW) but won’t tell me which one and that I just have to ‘wait-and-see’ tomorrow!

So, I will have to take a picture of the photo cake before it is cut into and post it!

How flattering is that! Big Grin here!!!

AHHHHH HA!

Okay, I made a new discovery on my blog. When I do a spell check and then post something I have noticed that it doesn’t always work. Well, I guess if I am done typing and do a spell check it isn’t saving it. But, if I do a spell check and type more it does. So, I have to do a spell check and then click ‘resume edit’ and all the spelling corrections will be saved!

Tetanus in developing countries

This is very moving. I am not a fan of diaper companies or other companies going to developing countries to ‘offer’ things, like the formula companies all have but this is still very special. It is something that I never even knew about either.

I did a search for tetanus on Wikipedia and found out that in the countries on the bottom right of Asia (Vietnam, Cambodia, Bangladesh, etc) actually have a higher percentage of infant mortality due to tetanus.

science experiment How much iron is in your cereal?

This is from Robert krampf. I LOVE this blog! He has been doing it for a few years and if you ever have a rainy day, are in need of a cool science experiment, need an idea for a science fair, etc. This is the place to look. If you sign up for his blog (via Yahoogroups) you will get a weekly experiment emailed to you. You can visit his website for past experiments and some videos.

http://www.krampf.com

For this week’s experiment, we are going to take some breakfast cereal apart, to see how they put in a full day’s requirement of iron. To try this, you will need:

– some enriched breakfast cereal. Be sure it provides 100% of the daily

requirement for iron.

– a plastic bag that you can seal

– water

– a powerful magnet

– a sheet of white paper

Pour about a cup of the cereal into the plastic bag. Then add about a cup of water. Seal the bag and start squeezing the cereal, breaking it up into a mush. Keep squishing the mixture until most of the solid chunks have broken down.

Then place the magnet against the side of the bag. Slosh the contents back and forth across the magnet, making sure that the magnet stays in contact with the side of the bag.

After a few seconds of sloshing, lay the bag down on the white paper, and let most of the cereal mush run to the side of the bag away from the magnet. Slowly move the magnet, and watch closely. You should see tiny, black specks following the magnet. What is that? Iron.

What! There are chunks of metal in my cereal? There sure are. When they make the cereal, they mix powered iron in with the grains, sugar, and other ingredients. Don’t worry. It’s safe. Your body absorbs some of the iron, keeping you healthy.

Now, besides showing us that we are eating metal, this also demonstrates that breakfast cereal is a mixture, not a compound.

Mixtures are just what their name suggests, several different substances mixed together. If you put some salt and some sugar into a bowl, you have a mixture. They are mixed together, but not chemically combined, which means that you could separate them without having to chemically break them down. In the case of the salt and sugar, you could sit there with a magnifying glass and tweezers, as long as you had a LONG time.

Compounds are substances that have all their ingredients chemically bonded together into a single chemical formula. For example, during photosynthesis, plants combine carbon and water to produce sugar. Even with a very powerful microscope, and a wonderful pair of micro-tweezers, you could not pick out the bits of carbon and water from a bowl of sugar. They have been chemically combined into a single compound, with the formula C12H22O11.

Yes, you can separate the carbon and water by burning the sugar, but that is a chemical reaction. Mixtures can be separated without chemical changes, and that is what you are doing with the cereal. The iron is not chemically bonded to the wheat, sugar, marshmallows, raisins, chocolate chips, or the toy prizes found at the bottom of the box of cereal. Once you soften the cereal, and break it into small bits, the pieces of iron are freed to stick to the magnet.

Of course, you could use milk instead of water, which would make it a bit harder to see the iron, but you would have a nice snack when you are done.

Have a wonder-filled week.
