Math

In this math unit we are doing patterns and relations. We are able to describe patterns on the graph of a linear relation, create a table of values using the points on the graph, determine the missing value in an ordered pair for a linear equation. Describe the relationship between the variables on a graph, decide if a table of values represents a linear relation, graph points from a table of values. Create a table of values by substituting in a linear equation, construct a graph from a linear equation using integers, and determine the missing value in an ordered pair for a given equation. 

For example, I will show you how to determine the missing value in an ordered pair for a linear equation. First you analyze the equation, for example, the equation is y= 3x. Now you find the x values, for example, the x values are 1,2,3,and 4. Now you do the first equation which is y= 3x (x= 1). The answer to the first equation is 3, because you multiply 3 and 1. And to finish the linear equation you just do the same thing with 2,3.and 4. 

 

Electromagnetic Spectrum

Electromagnetic spectrum is the term used to describe the whole range of different types of electromagnetic radiation. In light waves, electric and magnetic fields vibrate therefore light is classified as electromagnetic radiation. This is an energy that travels and spreads out as it goes. Hotter, more energetic objects create higher radiation than cooler objects.

Some types of electromagnetic radiation include: radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Visible light only takes up a small part of the spectrum. Everything on the spectrum may seem different, but they are still electromagnetic radiation.
