In this attempt we place vinegar into the bottle first then had the baking soda stuffed in the balloon. We noted that the vinegar / baking soda solution became cold during the mixing process.
Next we tried behind a wind block (the car), with baking soda added into the bottle with a vinegar filled balloon. In this experiment the boys and I learned not to do this way again. Because we could not add enough vinegar to react to the baking soda because -- a barrier is formed atop the baking soda when the two meet. Our hypothesis --- try again on a windless day, the solution cools during the reaction, and how the experiment is set up will affect its outcome.Hubby and I decided to start teaching stories from this Children's Bible to help give our boys some lessons in our faith that is centered in Christianity. Later in the year, I will introduce them to lessons from the Torah, Quran, Buddhist texts, and other 100+ faiths of the world. Also, this will give them some sort of religious foundation to build up from so they can make the decision about which faith they will follow if any.
Now who could not use some 'found monies?' I was doing a happy dance to finally recieve this check from the Texas Appliance Mail-In Rebate program. Wooo Hooo! Gotta love going green when it actually pays some green backs into ones' pockets. :O)
Finally, we were the recipiants of this lovely gift called rain. Let me tell you, our ground was so hard from lack of moisture; that small cracks can be found. I am guessing this little soaking gift from heaven will turn our grass green.
Now this is one website I wanted to pass on to all of you. I found it a few months back and there was not much to offer. However, since then Bill Gates has made a large donation and others to get this website up and fully functional. So I wanted to pass this information along to those: teaching, homeschooling, in college, or is helping out children with homework. http://www.khanacademy.org/
This website has thousands of videos with lessons from 9 to 15 mins in length showing how to work math problems and other subjects. So far there is an extensive amount of simple math, algebra, physics, finance, economics, accounting and many other subjects to be added. This website is free (accepts donations) and a parent can set up an account to monitor and track their students (children) working the problems or lessons they try. You can not beat free especially when it is a quality program.
Hope ya'll have a wonderful week.
