Interview

I had to interview one of my peers and find out what they wanted to do for their STEM project. Sharon King is one of my 22 STEM classmates. While talking with Sharon, I learned that she is interested in diseases. She would like to do her project on Lupus, a disease that has to do with your immune system attacking your body. Sharon is interested in Lupus because some of her family friends has it and it sounded interesting. There are 4 types of Lupus. They are Systemic Lupus Erythematosus, Discoid Lupus Erythematosus, Neonatal Lupus, & Drug induced Lupus Erythematosus. Sharon wants to study the effects that Lupus has on your body. She also wants to discover its symptoms, how it is obtained, the effects that it has on everyday lives, as well as a possible treatment. Sharon plans to complete her project by doing lots of research and possibly experimenting.

THE PLANT CELL

I had to create a powerpoint presentation of either a plant cell or animal cell, labeling all the organelles in that specific cell and real-world analogies for each organelle. I chose to make one on a plant cell and focus the analogies around farming.
Below are my slides on the plant cell.

Alternating & Direct Currents

I have been notified that when I talked about Nikola Tesla, I was not clear on the difference between AC (alternating currents) & DC (direct- current) electricity.

AC current is a specific type of electric current in which the direction of the current's flow is reversed, or alternated, regularly. Direct current is no different electrically from alternating current except for the fact that it flows in the same direction at all times.

AC is like doing "line jumping" exercises; going back and forth really fast

DC is like running a lap around a gym; go down on one side, then come back on the other

<-- AC <-- DC

KEY:

* - electrons

<> - direction the electrons are moving

l - pole

__ - wire

Hopefully, my explanation and images cleared up any questions :)
