The Amazing Naked Egg

Hey look, I'm actually blogging about something in the same week that we did it!  I've been dying to do this experiment that I found on Pinterest for a while. We really had fun with it and spent 5 days doing it!

We started by putting the egg in a cup and filling it with vinegar.  The kids made hypothesis of what they thought would happen.  Lincoln thought the egg would get rotten.  Savannah said she had read about this experiment in a book and that the egg shell would disappear. Sometimes having a smart kid is not so fun.  She has been able to guess the correct hypothesis on almost every experiment that we have done.

After about 24 hours of sitting the egg was mostly naked, but there was one spot that still had a bit of shell on it, so I moved the egg to a new cup and refilled it with clean vinegar.  I'm not sure if that was necessary or not, but the old one had a pretty good layer of white foam on the top from the shell, so I figured it couldn't hurt.

We let that sit for about another 12 hours, and we had a perfect rubbery naked egg.  We discussed that the vinegar is an acid and that it had eaten away at the calcium carbonate in the shell (similar to our bones!) and that's why it disappeared. The egg had also gotten a bit bigger, so we talked about what osmosis is.  Again, Savannah was able to deduct that the vinegar had gotten into the membrane of the egg, so there must be tiny holes in it that we can't see.  She really does amaze me!  This is what the naked egg looked like next to a regular egg the same size as this one started out.

I asked the kids if they wanted to try anything else with it, and without even being given possibilities, Lincoln wanted to see if we could make it even bigger.  We decided that in addition to that, we wanted to see if we could make it change colors too.  Kinda killing to birds with one stone, so to speak.  So we mixed up some blue water and put the egg in. 

I'm not entirely convinced that the egg got any bigger, but it did turn blue.  Much deeper blue than I had anticipated. 

Next, we decided to see if we could shrink the egg, so we put it in a cup and filled it with Karo syrup. 

I loved that with the blue coloring in the egg, you could totally see the separation of the water that came out of the egg and the Karo syrup. 

The egg totally SHRUNK!

Lincoln thought the half-full membrane sack was the coolest thing ever!

Savannah wanted to see if we could make the egg big again, so we put it back in the water.  We decided to use colored water again since it turned out so cool before.  This is what the egg looked like when we first put it in the water.

This is what it looked like 3 hours later!  I lifted it up to check on it, and it was too swollen to fit back to the bottom!

And the final product.

We were going to take it outside and try bouncing it on a cookie sheet starting from about an inch high and going higher and higher to see when it would break.  But, Lincoln accidentally knocked it off the counter and it exploded all over my kitchen.  I didn't take a picture, but I wish I had because the mess was bright green!  It was a perfect combination of the blue and yellow from the different experiments. 

This was by far the favorite science experiment that we have done.  It was so much fun, and easy too.  

The Princess and the Frog

The Princess and the Frog is a movie that I wanted to do for Friday Fun right from the start, but it took us a while to get to it.  Our first activity was Jazz Band.  We started by making shakers out of tin cans.  The kids decorated them with paper and markers, then we filled them with dry beans and rice and hot glued them shut. When they were done we looked up Jazz music on YouTube and the kids shook their cans and drummed on them with silverware.  Somehow, I didn't take any pictures of that.

Next we had frog races.  The kids hopped like frogs across the living room and the first to touch the opposite wall one.  I think they did it like 10 times in a row.

Food on this one pretty much planned itself.  How could we not do gumbo?  I had planned to make it from scratch, but I decided to get lazy and we had Zatarans with smoked sausage and shrimp.   We did green beans for our vegetable since there weren't any in the gumbo.  Fizzy Frog Soda was sparkling water with lime juice and green food coloring.  The beignets were my favorite part of the meal.  They are a fancy French pastry, but we made them quick and easy by cutting Pillsbury biscuits into fourths, frying them and dipping them still hot into powdered sugar or a cinnamon sugar mixture.  Everyone LOVED them.

Hotel Transylvania

We missed seeing Hotel Transylvania in theaters, so we did it for Friday Fun the week it was released on DVD, even though it wasn't October.  It is always hard to plan a movie night when I haven't seen the movie.  Luckily this movie is themed enough that it wasn't too hard.

Dinner was based entirely on the characters.  We did Mummy Dogs, Frankenstein's Fries (sweet potatoes roughly cut into fry shape and baked), Blood Juice (cranberry juice), and Big Foot Bait which was cake batter puppy chow. 

We started out by playing Monsterize Yourself on the movie's website. It looks like that game has been removed, but there is a Hotel Transylvania game. 

After that I sent the kids upstairs to change into their vampire costumes from Halloween.  When they came down I pretended to be a hotel check-in person (is there a name for that?) and after pretending to check them in on my computer, I handed them a key.  I showed them to their "room" which was just the bean bag in our tv room made up like a bed, and informed them that there would be a monster party in the hotel lobby in five minutes. 

  When they came back to the lobby/my dinning room I played Monster Mash on my laptop and they danced.   Finally they went back to their "room" to watch the movie. 

Volcano

My kids have been bugging me to teach them how to make a volcano for a really long time.  I got the idea to start doing "Science Saturdays" with them, and decided that this was the perfect project to start with.  I didn't want to deal with the whole hassle of making a volcano out of paper mache, so we simplified it and duct taped two plastic cups together and cut a hole in one for the top.  I thought it would be fun to add food coloring to the baking soda and vinegar to talk about color mixing as well.  We did blue in the baking soda and red in the vinegar.

Lincoln got the honor of pouring in the first of the vinegar.

It only fizzed a little bit.  I didn't actually look up any directions for this experiment, and looking back I probably should have used smaller cups.

So I used a funnel to add more baking soda, then let Savannah add more vinegar.  Then it worked much better.

When we were finished we discussed that baking soda is a base and vinegar is an acid and how a base and an acid cause a chemical reaction, which makes the foam. 

We Bought a Zoo

We Bought a Zoo is another that we did a long time ago.

Our first activity was, "act like an animal."  It was basically charades.  The kids took turns choosing any animal they wanted and pretending to be that animal.  The rest of us guessed.  It was pretty much impossible with the animals that they came up with.  Savannah was a cat, a lion and a cheetah.  Lincoln was an armadillo, and aardvark and a hawk.  Somehow I didn't take any pictures or video of this.  I think if I did this game again, I might print pictures of the animals and have them draw one to act out to make it a bit easier on the guessers.

Next we made a zoo.  This took a LOT more time than I expected because the kids got really into it.  They drew pictures of zoo animals and cut them out. They even made themselves zookeepers. Then we glued them to the bottom of a box that I had cut the lid off of, and taped on strips of cardboard (cut from the lid) to make a cage.  Not very accurate since all the animals were in one cage together, but the kids had a lot of fun making it!

For dinner we had "Zoo Stew" which was regular beef stew, "elephant ears" which were frybread, "Jungle Juice" (the little bottles of sugary punch you can buy at the gas station, similar to bug juice,) and "Gorilla Poops" otherwise known as no-bake cookies.  My kids both LOVED the meal, which was shocking since Lincoln had never before even tasted stew.

  

Mirror, Mirror

Mirror, Mirror was one of the first Friday Fun movies that we did.  It was almost a year ago, and I didn't take many pictures.  For our activities, during the day we "explored the haunted forest." Obviously it wasn't really haunted, I just took them on a fairly wooded hike they had never done before. 

Next, we made crowns out of construction paper.  The kids just cut a piece of paper and decorated with with jewels, then taped it into a crown.

For our dinner, we had "dwarf dogs" which were mini corndogs, "poison applesauce" which was regular applesauce colored green," "magic potion" which was Sprite with some food coloring, and finally we walked down to the snowcone stand near our house to get snowcones before watching the movie.

Unlucky

Savannah is working on a family history project for school.  We were printing out pictures for her to use, and had the following conversation with Lincoln:

Linc: Who's that?
Me: That's Michael's sister.
Linc: Michael has a sister?
Me: He has 3 sisters.
Linc: He has 3 sisters and 3 daughters?  He's really unlucky!
Me: How many sisters do you have?
Linc: 4, I'm unlucky too.
