There’s a twofer going on tonight. However, it’s only one post.
is for research. I can answer the boys questions without Google. What I can’t do is answer them thoroughly. If you can’t explain it simply enough for a 6 year old to understand you don’t understand it well enough. So I turn to Google to refine and finish my explanations. I know that’s not official research, but it’s good enough for now. As long as I use trustworthy sites.
Since I love their questions, I pray they continue to ask questions their entire life. Learning is essential and questions are proof they are trying. S is for students. Students of education. Students of life. Students for life.
1. What is cholesterol?
I had to admit defeat on this one. All I could them them is that it’s stuff in our blood and there two kinds, a good kind and a bad kind. Now I know the bad kind is LDL – low density lipoprotein. It’s sticky and is the stuff that clings to artery walls, reducing blood flow to the heart, and causes heart attacks. The only thing that can stop a bad cholesterol with a gun is a good cholesterol with gun. HDL – high density lipoprotein strolls the blood stream looking for LDLs. Once it finds it, it latches on and delivers the baddie to the liver (the judge who sentences the baddie to jail). The liver then filters it as a waste product and removes it from your body all together.
2. What is it when shadows combine without touching?
That’s kind of a confusing question, isn’t it? How can two things combine without touching? That’s like putting your clothes in the washing machine and they never get wet. You can do this experiment and see it for yourself. Just hold your hands up to a wall to cast two shadows. Bring your hands together slowly and the two shadows will touch just before your hands do. The shadows will be connected yet your hands are not. Thanks to Vsauce on YouTube, we know this is called The Shadow Blister Effect. I highly recommend the video. It has to do with the anatomy of a shadow. The umbra is the part of the shadow where the light is fully blocked. The prenumbra is a partial blocking (like twilight, the sun has set, but it’s still a bit light). When the two prenumbras overlap it creates a significantly greater darkness which we perceive as the combination of shadows even though the two objects aren’t touching.
3. Why do we get blisters?
You got a blister because you wore your rainboots with no socks. Put socks on before it gets worse. There are several causes of blisters. Heat, friction, and chemicals are just three of the main culprits. A blister is our skin’s way of defending itself. A layer of liquid forms between the top layers of skin to protect the tissue below it. It is best to keep the blister as long as you can. But if you’re like me and love bubble wrap, it’ll be too tempting to pop your skin bubble. That bubble is allowing the tissue to heal without the risk of infection. So if you do pop your bubble, clean it and wrap it up.
4. Can I get Facebook?
Hold on… I’ll go ask Zuckerburg. Sorry. He said awe hell no. Sure, it’s a great tool to keep in touch with family and friends. It’s also a great tool to kill some time, whether it be a few minutes or a few days. It’s also a great place to get #FakeNews and other things unimportant to our daily lives. Though, if he did get the FB he would just have a few family members on so it would probably be safe until he went exploring for more. So, no. The 10 year old will not be on Facebook for a while, yet.
