I learned that the earth is made up with 3 different layers. The outside layer is the crust, which is the land that we are on top of right now, unless you’re in space. The sEcon’s layer is called the mantle which is made of rocks and is the largest layer. The last layer is the core. Which scientists believe is a bunch of molten metal.
Today I learned about the sun on Brain Pop jr. I learned that we would not survive without the sun. The sun is made up of two main gasses, hydrogen and helium. Plus lots of particles of dust and rock. Once I watched a Netflix episode on Story Bots and learned how the sun was formed. There was ginormous cloud of dust and gas particles and soon all the particles started to bind together and made heat. Then it became a giant sun. Our sun is actually a medium sized star.
I learned where gas and energy canes from. We can get energy from gasoline and other sources. Petroleum is deep underground and we use it to make gasoline and plastic. Fossil fuels are basically just fuel made from the bones of other animals But fossil fuel takes a really long time to form. Another thing we can use to create energy is dams. We create hydroelectric energy from dams. I live right next to a dam on the snake river in American Falls. That is pretty cool. Another thing is Solar panels. Solar panels collect energy from the sun and give us electricity.
When you learn about variables it is kind of a tricky subject. It is an equation with letters and numbers in it. The letters in it are called variable. It’s like a mystery and you have to find out what the letter is! It’s a number in disguise. The way to get it is by using multiplying, dividing, adding and subtracting to get the letter by itself. What ever you add or multiply on one side you have to do the same thing on the other side too. It is pretty tricky
I’m learning about decimals. The number to the right of a decimal is a tenth. A tenth is like a fraction. It is smaller than one. If you took one and broke it into 10 pieces that is a tenth. I am practicing converting decimals into fractions and fractions into decimals because they mean the same thing.
I am working on my language arts curriculum and am practicing homophones and poetry. My poem is a little bit silly though
