It’s week 6 of the Student Blogging Challenge, and it’s time to get educational! Science is really important in our of our lives. It affects all of us in ways we don’t realize.

The first task is to research and write about something you’re curious about. The thing that I’m curious about is the weight of a kilogram changing. That’s a weird sentence, right? A kilogram is a measurement, so how is it changing? Well, I’ve done more research into the subject, and there’s actually a really interesting answer. The weight of a kilogram is based on the weight of an object in Paris. The metal cylinder that has been exactly one kilogram since 1889 is slowly losing weight. This is because different things used to maintain it have taken away millionths and billionths of a kiliogram- from the kilogram. Since it’s super impractical to have different amounts for the same measurements, the weight of a kilogram will no longer be based on a physical object. The new weight of a kilogram will be based on physics! How? Well, it’s really complicated, but there’ll be this tiny little thing, called the Planck Constant, which can be used to find the weight of a kilogram. It’s called a constant because it is just that- constant. It will never change, unlike the physical weight. I know this is confusing, so here’s some articles about it.

One of the other tasks that’s part of Week 6 of the Student Blogging Challenge is to find a science video that I like, and share it! I chose this video because I thought it was interesting, and it described Newton’s laws of motion more in-depth than I’ve seen before.

The last task I’m completing for this week of the Blogging Challenge is to create a science-based Two Truths and a Lie. Here’s three statements relating to the first task:

1. There’s been one object used as the kilogram since 1889.

2. The weight of a kilogram is changing.

3. The object that is exactly one kilogram is in London.

Feel free to leave a comment with what you think the lie is!
