Blood!

We've been learning a lot about the heart along with arteries, veins, and capillaries. So we took the time to make some blood that the girls will never forget. Here are the instructions: 1. Fill a jar with water, you could put in a little yellow food coloring to make it look like plasma. 2. Take some cheerios and put them in a zip lock back and shake them around with red food coloring. This makes the red blood cells. 3. Pour the red blood cells, white blood cells (white marshmallows), and platelets (purple pom poms) in to the jar. Then you have something interesting to look at.
Along with this little activity - we filled up 5 liters of water and poured it in a huge bowl. I made the girls guess how much blood we have in the average adult size body - their guesses were 5 gallons, 10 gallons, etc. So when they learned it was just a little over a gallon, they were quite surprised. This opened up a lot of discussions like getting shot in an artery, etc.

Where's the line to see Jesus?

My eight year old has discovered the truth about Santa. "He's not REAL!" is what she keeps arguing with my six year old. This morning, Ashlyn, my youngest and I were up all alone in the house and she came to sit on my lap and just flat out asked me, "Is he real, Mommy?" We didn't want to force this question from her, because we've wanted to let her have her childhood and pretend. Well, when she came up and asked it - I had no choice to tell her the truth. And this is what I told her... "His name was Nicholas, and we call him St. Nicholas, because saint means someone who belongs to God, just like we do. In St. Nicholas' town there were many poor children. They didn't have enough food, clothes, or toys. St. Nicholas used his money to buy food, clothes, and toys for the poor children. He didn't want them to be embarrassed by his gifts, so he gave secretly." "St. Nicholas also told everyone about Jesus and how much God loved...

Solar System Bracelets

Well, it was that time again - to learn about the solar system, galaxies, how we get our seasons, the moon phases, etc. You can check out our Space Unit that we completed a couple years ago, when we covered space. Meant To Teach: What's out there in space??? Also, here is the solar system we completed a couple of years ago. Meant To Teach: Solar System Complete This time I decided to do something different with the girls. I might add, it was also much easier than our solar system above. I decided to do solar bracelets this time!

How We Do Current Events as an Elective and Why I Think it is Important

When I sat down with my high schooler with a list of electives she could choose from to do this year, she chose current events as one of those. I thought I'd write a post on what we do for our current event subject. Each morning we start off with Channel One News . I was so glad when I came upon this website because I remember being in school and Channel One News came on every morning and we had to watch it in class. I'm not trying to make our homeschool like "public school", but my oldest and I grab a cup of coffee and just cozy up to watch the news like many Americans do in the morning. So I was thrilled to find it. It is definitely a news source that relates to middle school and high school students, even teaching them a "n ews related  word of the day" that they may hear in stories in the video. Sometimes there are even polls that you can vote on after the video and they could be featured in the next day video. We participated in one of the polls on ou...
