How Much Salt Does it Take to Make an Egg Float?

The oldest is doing Oceanography this year. She had a reading on "Why is the Sea Salty?" from Wonderopolis. At the end of her reading we completed a lab on making an egg float.

From Wonderopolis, "You don't have to travel all the way to the Dead Sea to become an egg-spert on salt-water buoyancy. Try this fun experiment to learn how to make an egg float using nothing but salt and water!"

Of course, I made her do a write up on her lab for portfolio purposes.

We've done a similar experiment in the past called Sink or Float. You can find that here.

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...
