Rebecca took a chicken egg, and soaked it in white distilled vinegar for 2 days.
Her theory was that since vinegar was used to dissolve calcium buildups in household cleaning of bathrooms and kitchens, it would also dissolve the chicken egg shell.
At the end of 2 days, she checked it. The shell was completely gone, and the egg was rather rubbery. If you hold it up to the light, you can see the yolk and the inside of the egg.
You can see the yolk in the center of the egg, as a light is behind it. The shell is gone, and the egg is rubbery.
Kind of a neat homeschool science experiment that anyone of any age can do. This would make a good experiment for younger ones for a science fair, such as the one in St Joseph MO every February for homeschoolers. Soak the egg in other liquids and see if any other liquids can have the same effect. We always here how bad soda pop is on our teeth, I wonder what would happen to the shell if an egg were soaked in soda pop?

One more crossed off the list
I got another craft project crossed off the list today. When my husband and I married almost 6 years ago, I moved into his home. I always love the idea of a large bulletin board in the kitchen of the house, and he had one that fit the bill. But, it is a little bland. So, for 6 years I have been meaning to add some sort of interest to it, and finally got it done today.
First, I'll say it stands across the hall from my large antique potato bin--so, I went with the potato theme, which fits a kitchen.
I measured the bulletin board, and went on the hunt to find a potato sack that would fit the board. I found one on e-bay that was a good size. It arrived today, and thankfully it didn't smell too bad. Often, burlap will have a smell and need to be aired out well, or cold water washed and drip dry, or even dusted with baking soda for a few days before you can work with it-but not this one.
I then took the bulletin board off the wall. I then discovered the frame on it could not be removed, so I couldn't do my original plan of removing the frame, adding the burlap and then re-framing it. So, I went to plan B.
I measured the inside of the board (inside the frame) twice, as my husbands motto is measure twice, cut once. I then cut the burlap bag, so that the back of the bag came off (saving it for a future project). Then I centered (best I could--when the bag was printed it wasn't quite center--it was made for hauling potatoes, not bulletin boards in a farm house...). I then laid it over the board and stretched it, and temporarily stapled it into place to hold it. Next, I took a butter knife and poked the edges under the wooden frame. Then I removed the staples, and put in new staples along the edge of the frame, where they can't be seen.
Then, I rehung it. So far I have only put the calendar back on it--it will fill up soon enough.
This is the potato bin across the hall from the board. I think it was probably made in the late 1800's. I bought it last fall at an antique store in the city. It is missing one size of tongue and grove which happens to be the same size of what is on our front porch, which we will be doing some repairs on when we get some warmer weather. So, I can fix that with the wood we remove from the porch, and I have enough of the green stain left to make it match.
Monday we used a carrot for something, and I saved the top. The two preschoolers like doing this. I put the top in a jar with a small amount of water, then placed it in a sunny window. (You have to keep an eye on the water-don't let it go dry). In a few days you will start to see growth on the top, and depending on the carrot variety, it may grow up to a foot tall. It is rather lacy and pretty to look at, and the little ones like checking its progress.
Inexpensive homeschooling fun and learning! This makes a good science project for preschoolers or kindergartners--to see what fruits and vegetables this will work for, and which it doesn't.

Another upcoming Science Fair for NW Missouri homeschoolers
MARSEF at Missouri Western on March 9 is for grades 9-12. Homeschoolers are most definitely welcome to participate if they live in our region. Anyone living in Platte county should apply to the Kansas City fair. There is also the Junior High MARSEF on March 12. That is run by the St. Joseph school district. Information can be found here: http://www.sjsd.k12.mo.us/Page/11475
Yes, we can extend the deadline. If you fill out the SRC forms found on our website(http://www.missouriwestern.edu/orgs/marsef/), we can process them ASAP. There might be some cases that we will not be able to accept, if they required Scientific Review Committee (SRC) approval before experimentation began, but did not receive it. However, if someone qualified checked out the project before it started, they can act as SRC. (I know there are a lot of rules, but we have to follow the rules of ISEF to send out students there.)
We would be very excited to see what your students have been doing! If you have any more questions, please don't hesitate to contact me.

Science Fair tonight
Tonight is the area homeschoolers science fair. Even though we have known about it for 12 months, and been working on it for months, we have the last minute scramble going on.
One is taking her fossil collection and a board about fossils. Many of the fossils in her collections are ones that she, I and her sisters dug while in Utah several years ago. We stopped at a place I saw on a TV vacation channel called u dig fossils. http://u-digfossils.com/. We have sent several other homeschooling families their direction as well. Other information she researched, including info from Matt Miles at Creation Truth. http://www.creationtruth.com/. Matt came as missionary to church camp last year, brought lots of fossils and other interesting items.
Another is taking her rockets--both those she has bought in kit form, and the ones she has made from odds and ends around the house. Yes, they really do fly, and all but one came back to earth. (Really we were expecting a phone call from NASA regarding the one that didn't come back. It was her largest and fastest. It went up, up, up, no wind, should have come back down fairly close to where it went up from. It didn't). The rockets she builds are from Estes.
I notice every year when I mention the science fair on my blog, I get tons of hits. I presume people are looking for science fair ideas. Here are a few we have done, or have seen at various science fairs....
growing bacteria in petri dishes, by collecting the bacteria from family and pets and various surfaces; rockets; how airplanes fly; fossil collection; parts of a plant; plants grown in light vs plants grown in dark; objects (small clocks or LED lights that run off of home made batteries, such as lemon, oranges, potato, vinegar, pickle, juice...); growing mold on various foods and various tempatures; comparing the weight of mice that started out the same, but one was fed good food and had an exercise wheel, while the other was fed junk food with no exercise wheel; jaw bones of various animals with the teeth intact and identified, to show how meat eating animals differ from those that don't eat meat; home made engines that run off of rubbing alcohol; leaf rubbings and collections-all classified; models of the earth and planets
You can also visit lots of unline sites for ideas,

You know you are a homeschooling mom when.....
You brake for skeletons that are in the ditch (that sounds so much nicer than roadkill remains)........
Most likely this was a deer.
We also have an unidentified small animal, and a cow.
Now that we have a collection of sorts going, it will probably become a science fair project in the future. They will be neat to identify, label and mount.
What weird things do you do for your kids?

Science Fair Results



For the third year, tonight the girls entered projects in the Homeschool Science Fair in St Joseph MO. The fair is open for all homeschool students, preschool through senior. Since we have been attending the fairs have been at the St. James Catholic Church. As before there was a roomful of exhibits showing a lot of talent. Projects ranged from ph levels, to electricity projects, honey bees, and more.
This year, Elizabeth did a project on rabbits, and came in 3rd for her age division. Emily's project was on ph levels, and Rebecca's was on DNA. They each took an honorable mention.

Steer butchered today
Thanks to some friends, as they actually did the work. Butchering is brand new to JD and I, and we had no clue what to do. This steer was crazy--tore up fence, got out often, charged me and JD, even charged his own reflection in the pond. He had to go. Trouble was, he had no intention of getting into the trailer to take a ride to the butcher. The state laws say he has to arrive alive, so the idea of shooting him here, then delivering him was out.
So, some friends of ours came over (thanks Eddie and Jenny!) and the men shot him, and shot him. He refused to go down. Finally he did. We got him skinned and ready to the point of starting to cut the meat cuts we want tomorrow. It was cold, 31 degrees. We started a little after 9 this morning.
Around 6 we took him to another set of friends (Craig and Kelly's) and put him in their building. The have a nice area where we can finish up tomorrow out of the wind!
He is huge. Much bigger than we thought--somehow he looked smaller in the pasture. Having never done this before, we had no idea what we were getting into. We just knew we didn't want to have him on the farm for another summer and that we didn't want to butcher him after the weather got warm. We are glad to be rid of him, and all involved will have meat for the freezers.
Tomorrow evening the girls are in a science fair in St Joseph MO. We have a volcano, weather research and information on recycling and trash. They will be finishing up the final touches tomorrow after church, so us girls may miss out on part of day 2 of the butchering.

St Joseph MO Science Fair for Homeschoolers
Homeschool Science Fair 2009
There’s still time to consider an entry for the Science Fair!
any type of report, experiment, invention, or display
that relates to your science studies or interest
(grade appropriate with a little help from your teacher).
Sunday evening, Feb. 22
St. James Church Cafeteria (King Hill Ave.)
Preschool through 12th grade divisions
6:30 pm =Setup
7:00 =Will Stuck, Science Show
8:00 =Awards
$5 per family entry fee suggested; prizes for all;
Drinks provided; bring a snack to share.
Register ahead of time with CandisesCrew@sbcglobal.net by sending the children’s full name and grade
Or mail with payment to: Schmidlings, 18 Eastwood Drive, St. Joseph, MO 64506
My best tips:
1Watch the sales and coupons at Hobby Lobby to buy the science fair display boards and headers more cheaply.
2Younger students seem to like making a report, middle elementary seem to really enjoy doing an experiment or making an invention, and high schoolers needs a greater level of difficulty.
3The library has experiment books and “Kids Discover” magazines to coordinate with the science subject you are already studying at home.
