The Magic Floating Egg

Last year, I received this Pop Bottle Science Kit for a gift. We decided to try it out today with some supplies that we already had hanging around.

For this experiment, you need your pop bottle with the top part removed (or a large jar will do), water, two eggs, and salt.

Fill your container 1/4 cup full of water. Break an uncooked egg into the water.

The egg yolk should sink to the bottom of the container.

Dump out the water and egg and fill up the container 1/4 full of water. Add salt and stir until the salt doesn't dissolve anymore.

Dad is checking to see if we have any undissolved salt in the water. It won't dissolve, so that must mean we have the right amount of salt for this experiment.

Break an uncooked egg into the salt water.

Now the egg yolk should float.

Slowly dribble water down the side of your container, being careful not to mix the fresh water with the salt water. Doing this is much easier if you use a turkey baster!

If the fresh water stays separate, the egg will float on top of the salt water and at the bottom of the fresh water!

According to the Pop Bottle Science Manual, this happens because: "An egg will sink in fresh water but float in salt water. Fresh water is less dense than salt water (and less dense than an egg). If you pour fresh water in the ocean, it will float around on the surface until diffusion mixes the molecules and the fresh water becomes salt water." Thanks for checking out my blog! I will be posting again soon!

Explore UT

Today we went to Explore UT. We just concentrated on Engineering. I built a structure out of toothpicks and marshmallows. My goal was to build it so that it would withstand an earthquake. After I made my structure, I tested it to see how earthquake proof it was. It was placed on an earthquake similator. My structure did suffer some slight damage, but nothing too major.

My New Puppy

Here's my new puppy. His name is Bowser. He was born on October 6th, 2009 and is 2 months old now. He likes to chew on EVERYTHING and he sure does go potty a lot! He is a Soft-Coated Wheaten Terrier and will get up to about 35 lbs. Here is a picture of a full grown Wheaten Terrier. Notice the change in hair color. Bowser will eventually become this color, too.

Surfin' Safari

My Aunt Juli took me to the Wisconsin Dells and we went to an indoor waterpark called Kalahari. It was a lot of fun and had so many thrilling rides. I decided to try some body surfing. I was the youngest person in line, but I still wanted to do it. On my first try, I wiped out big time----check out the video:

On my second try, I did GREAT!!! I rode for a long, long time. It was so much fun!!! Check it out:

Walking With Dinosaurs

My mom and I went to see Walking With Dinosaurs at the Cedar Park Center. The dinosaurs were very realistic and were life-size. Some of the dinosaurs we got to see were Allosaurus, Utahraptor, Ankylosaurus, Brachiosaurus, Plateosaurus, Stegasaurus, Plateosaurus, and Tyrannosaurus Rex. The T-Rex was by far my favorite. The show was a little scary at times and very loud, but I really enjoyed it. I would definitely like to see it again.

Holey Leakproof Bag of Water!!!!!!!!!!!

Materials Needed:

• ziplock bag
• pencils
• pencil sharpener
• water
• food coloring

Step 1: Sharpen your pencils with a pencil sharpener. In order for this experiment to work, the pencil points need to be very sharp.






Step 2: Fill the ziplock bag halfway full of water.



Step 3: For contrast, add some drops of food coloring. Seal the bag.

Step 4: Take sharp pencils and poke them into the bag of water, using a circular motion. Do you see any leaks? NOPE!!!

Step 5: Slowly remove pencils and observe what happens. Now you have some leaks!

The Science behind the experiment:

Zip Lock bags are made from plastic. Plastic is made of polymers which are long chains of molecules cross linked together. Polymers are what makes plastic bags and balloons stretchy. When we poke through the zip lock bag with pencils the polymers are pushed aside but remain bonded by the cross-links - keeping the water inside. The polymers re-seal around the pencil. Amazing!

Eagle Pride Award

The principal invited us to a reception this week. Connor was being honored for being an "Eagle Pride" student. He got an award for outstanding behavior. We are so proud of him!
