I'm a mom, a teacher, a student, a wife, and a scout leader. I am actually an education major currently working on my practicum in a 2nd grade classroom. I also home school my two children. I'm also a cub scout leader, a girl scout leader, and at church I'm the children's music leader. ;) I tend to stay a little busy. My state requires homeschoolers to keep a portfolio. I am going to use this blog as my portfolio.
This science curriculum is one of the kids' favorite things to do! We do an experiment and then talk about why it happened. In the picture above, the kids were learning about how heat and cold can affect the size of solids. In this image above, we heated a quarter. Then, I put it in this tool (don't know names of tools -- maybe an adjustable wrench?) As it cooled, it shrunk back down and fell out of it. It was kind of cool. This was last week.
This week we learned about air is a mixture. So, in this picture above we lit the candle. Then we put baking soda and vinegar in a jar which created carbon dioxide. We then "poured" the carbon dioxide (not the vinegar) over the candle and put the fire out. It was pretty cool. Then, we did Q & A until the kids figured out what happened -- carbon dioxide is heavier than hydrogen and oxygen so it snuffed out the candle. It was cool.
This one was neat too. It went with our air is a mixture chapter as well. I lit a birthday candle and poured a small amount of wax into the bottom of a bowl and stuck the candle to it so it would stand. Then we poured a half cup of water in the bowl and turned the glass upside down over it. As the candle burned up the oxygen, the glass sucked in the water to take the place of the oxygen burned. Once all the oxygen was gone and only nitrogen, then the candle went out. We did it several times.
