I'm going to do something called the photo of the day. Its always science related, but its fun!! I post a picture and then ask a question. U give ur best answer or guess based off of what u have learned and then I will give u the correct answer.
Also, its called the photo of the day so I will post one Everyday, or at least as much as I can. Ok! Here is the first one!  We had graupel today, but it is gone now. Without looking it up, what is graupel?Btw the picture is just to make it seem more interesting. It may or many not have anything to do with graupel..... |

Haha, ur guess is as good as mine before I knew.
Graupel is a type of precipitation similar to snow. The difference is that instead of being flakes, it falls as tiny snowballs. They are not hard ice, like hail. They are not wet or slushy. They are fluffy round balls of snow. It forms when snow flakes fall through tiny droplets of supercooled water in the air. The droplets freeze onto the snow, forming the graupel.
So why did I put up the photo of mule deer? Well we have these deer come by my friends house everyday. Since the graupel was gone, and I did not want to give away what it was, I thought this photo would work. In case you would like to see graupel, here is a photo.

I had no idea that existed! I thought there was only snow, rain or hail. I'm learning so much with you! You're like an encyclopedia!  |

It is the operculum from a large Moon Snail. The operculum acts as a door for the shell. When the snail is threatened, it pulls inside, and uses the operculum to block the entrance.
As the snail grows, it adds to the operculum just as it adds to its shell. That way, the "door" always fits tightly. Not all snails have an operculum, and they vary tremendously in their color and texture:)

TODAYS PICTURE OF THE DAY IS:  The wood in this pile will be reduced to this much ash when it is burned. What happens to the rest of the mass from the wood?

Wood is mostly made up of cellulose, a very long molecule that is really a chain of sugar molecules. (This is why termites love wood so much.)
The plant makes that sugar from carbon dioxide and water, with energy from sunlight in the process of photosynthesis.
When you burn the wood, you get back the energy, mostly in the form of light and heat. That energy was stored in the chemical bonds, and is released when those bonds are broken. You also get back carbon dioxide and water vapor, both of which are gases.
Those gases go up the chimney. The gray ash that is left behind is mostly the material that the tree took out of the soil. If you combined the mass of the ash with the mass of all the carbon dioxide and water vapor, it would equal the mass of the original pile of wood. None of the mass is destroyed or converted into energy.

Woow interesting! I had actually never stopped to think why things lose mass when they burn! Good job noob!
