Naked Egg and Osmosis

I'll be honest here, the main reason I keep a blog is so I can go back sometimes and remember what we did. This is especially the case now as we are now in the high school years. One of the universities in our area actually requires homeschoolers to list a lab and explain it, even down to the materials that we use. This is part of their application process. So this will be helpful in remembering what we did.

Anyways, I don't have very many pictures for this lab, because well - I dropped the ball as we had family in town and forgot to take pictures.

The first step to this lab is to get a naked egg (or two depending on how you choose to perform the experiment). If you aren't sure how to get a naked egg, you place it in vinegar for 24 hours. It's a pretty easy process.

The things you will need for this lab are:

Corn Syrup
Water
Food Coloring
Glasses
2 Naked Eggs (or 1 if you do it the way we did)

The experiment for osmosis can be seen in this video: https://www.youtube.com/watch?v=FyYz-1gqt68. We changed it up in just putting one egg in corn syrup and then putting it in water the next day to see the change.

We're loving doing these labs as they are definitely reinforcing what my high schooler has been reading during the week in the text.

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!

Behavior Chart

I found a behavior chart image online that I really liked because it detailed, but I couldn't find a website to print one. So I made my own. I did this in photoshop and if you would like to print one for yourself you can here . After I printed it, I hung it in a picture frame and can use dry erase markers to check off.

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...
