special post

Hi,
 today we have a special post.I do one of these every 20 posts.As we all know Earth day is coming up.So I have come up with some ways to help the earth.Number 1.Try to pick up trash when you see one the ground.It is important that we keep our planet clean.Number 2.Try to recycle and reuse glass bottles and news papers.Don't put food scraps into the garbage, try to make compost out of it.Number 3.

Try to not drive the car as much and ride bikes instead.Number 4.You could plant a tree to produce more seeds to grow more trees.Trees are the source to our lives.Trees give us the shade we need and the air we breath.

And the most important,NUMBER 5.Do every thing you can to protect the earth.The earth is the place we live.We would all not be here with out it.It is our home that we must protect.The earth is the source of our food and water.So you see we must protect it.So get out and HELP THE WORLD.You can make a difference.

slope 2

Hi,

Today we are going to continue talking about slops.In this post we are going to talk about horizontal lines or no slope, undefined, and a short cut to find slope without graphing.No slope is when you graph it and it comes out in a horizontal line and undefined is when it is A straight vertical line.

The short cut is to take the 2 points and subtract x from the other x and y from the other y.Once you are done put y over x in fraction form and simplify.Keep it in a fraction always.That would be the slope.You can only use this way if you have 2 points.

slopes

Hi,
today we are going to talk about slopes.To find slope you must know how to graph points.Slope is the measure of steepness of aa line.The ratio of the vertical over horasontal.A line with a positive slpoe goes upwards and a slope with a negitive slope is going downward.

The formula is always y=mx+b.M stands for the slope and b stands for the y-intercept.If it is a horisantle line it is a no slope or 0 slope.If it is vertical it is undifined.Once you have the slope and one point you can find the other points and find the line.We will continue this next post.

graphing points.

Hi,
today we are going to talk about how to graph points.Graphing points is realy easy and it dosent require anything but a graph and coradnits.cordinates look like this-(2,3)-They can be ether nege.itive or positive but let us stick with the positive.The graph looks like this.The graph could go forever.

Let us plot something.let us take the one that I used as an example.(2,3).So we always then up.So we go 2 across and then 3 up. There is our point.That is realy it so thank you.

rock cycle.

Hi,
Today we are going to talk about the rock cycle. The rock cycle is the process that witch the rocks go through.This a picture of it.As you can see there is many ways that rocks can go.It is an endless circle.


I will explain it.Lets start at metamorphic.It can ether be melted or be turned into sediment.Sediment then squeezes together and becomes sedimentary.It then goes through heat or erosion.Once heated it turns back to metamorphic.And so on.

stand off

Hi,
today we are battle pemdas vs. percent.This is the very time to decide witch is better.Nobody would ever know that this would ever happen.But fate has broght us to this momunt.

PEMDAS
The advantages are that pemdas is a thing that you know what to do first, and it is an algorithm.P=parenthies,      E=exponents, M or D=multiplcation and divtion, A or S=Adding and subtracting.The disadvanteges are that it is confusing and it can sometimes be super long.

Percent
The advanteges of  percent are that there are magic numbers that can be very helpfull like 2,4,5,10,20,25,50,100,9 and 99.If it is any of these numbers then it would be very easy, like 1/2 would be 50% and so on.The disadventeges are that it is very hard to find the percent of a number if it is not 100.

Poll
Now vote on the side bar.Vote, vote, VOTE,vote,VOTE!!!!Please.

constallations

Hi,
today we are going to talk about constalations.They are pictures that are made by stars.The most common ones are the big dipper and Orion..Their names are usaly  Greek.They can either be an animal or person.Some constalitions are only seen in a single season and some are seen every season.sinse 1922 88 constalations are named and seen.

some constalations can have more than 10 stars.Some might have little ones in them.There are more than 100 that havn't been identified.
