Sierra Summit

Sierra Summit 005

Sierra Summit 003

We went up to Sierra Summit for the weekend to snowboard. It was our first time up in the snow. I really wanted to start off with learning how to ski as I heard it was a lot easier to learn but.... snowboarding just looks a lot more fun!! So we opted to snowboard. I placed Tianna in a Kids Day Camp for several hours. It included lunch and four hours of snowboard lessons. I took a two hour introductory course.

Kids just learn so much quicker because they aren't afraid of falling down and they want to go faster. It appears, the faster you go, the better you are at balancing. By the end of the day, she was ready for the bunny slopes and I had given up after falling down so many times. Next year....

3rd Grade Science Project - Atmospheric Pressure (Egg in Bottle)

My daughter's science project was due today. We spent all last night finishing up the project that we waited til the last minute to do because

Where do you buy milk bottles these days?















So in a nutshell, when you place a lit paper into the bottle, the air inside heated up and expanded. When the flame died, the air inside the bottle cooled and contracted resulting in less air pressure inside the bottle than atmospheric pressure outside. The atmospheric pressure pushed the egg inside the bottle.

To get the egg out, you simply place the egg near the whole and blow into into as hard as you can. This causes the air pressure inside the egg to be greater than atmospheric pressure and the egg is pushed out.

It was a pretty fun experiment and mighty popular. I found many different versions of this on utube.
