Science Experiment: A Floating Egg?

I took an egg out of the fridge and waited for it to get at room temperature, then I took out to container of salt, a teaspoon, a spoon to stir with, and a glass filled with water.


I dropped the egg in the cup and it sunk straight to the bottom of the glass.
Then I took the salt container and poured some salt into the teaspoon. I poured the salt into the glass .
I stirred the salt in the glass and waited for it to dissolve.
Here is were I dropped the egg into the glass after it the salt dissolved, the egg floated for a little bit then sunk to the bottom, this was after I added the first teaspoon of salt.
My Science book had told me to repeat this until the egg floated to the top, it took four more teaspoons of salt for the egg to float to the top of the glass.
The goal of this experiment was to see if salt changed the density of items. It was a fun experiment and I'm glad it turned out well.

Science Experiment: A chemical reaction

My next science experiment was the most fun so far. I had took a 2 liter bottle and filled it with vinegar. Then I had to take some cabbage leaves and boil them in water. After that I took the leaves out and put ice cubes in the juice to cool it down. The next thing I did was fill a balloon with baking soda, then I poured the cabbage juice in with the vinegar. Here is were it gets exiting, I poured the baking soda out of the balloon by using a funnel, then the new liquid started to fizz and they balloon blew up, also the liquid in the bottle turned blue! This happens when one items atoms combine with the other items atoms to form a new substance, The vinegar an the baking soda formed together to make 3 new substances, they made Carbon dioxide, sodium acetate, and water, then the chemical in the cabbage leaves mixed with the vinegar and turned it purple. When the vinegar was transformed into a new substance it turned the cabbage juice blue. This is just another amazing fact that God has made us wonderfully and loves us dearly.



these are all the items I used.




In this picture I am putting the baking soda in the balloon








This is were it started to change purple when I added the cabbage juice and then blue when I added the baking soda



And this is the finished project doesn't it look nice?!

Science Experiment: Atomic Motion

I had to do another science experiment, but this time I did it on atoms in motion. First I had to boil some water on the stove. Then after it was done boiling I had to fill a glass jar with the boiled water, then I had to get another glass jar and fill it with cold water. When I was done filling the jars with the water I put a drop of green food coloring in the jar with hot water then a drop of blue food coloring in the cold water jar. The food coloring in the hot water jar spread more quickly than the one in cold jar. This explains that atoms move faster in an object when hot than when an object is cold. The videos below should show my results. It was a fun project than still proves God amazing love for us.
