Neuron Communication
Neuron Function. There are 3 neurons that do different things, motor, sensory, and relay. The relay neurons allow the motor and sensory neurons to communicate with each other. The motor neurons communicate from the brain and spinal cord to the muscles. The sensory neuron collects information from sensory receptor and transmits it to the brain.
Action potential is how the pulses are sent through the nerves. Inside the nerve membrane it is negatively charged with potassium and outside the nerve membrane there is positively charged sodium. In polarization the positive charge goes inside and the negative charge goes outside. In depolarization the positive goes out and the negative goes in. Through using polarization and depolarization a charge gets sent to the end of the nerve and synapse happens.
Synapse is when the electrical pulse sent through the nerves through neurotransmitters to the axon button. It is then turned into a chemical pulse to cross the synaptic gap. It goes through the postsynaptic membrane and through the Neurotransmitter receivers to the dendrite of the receiving.

A) I use the plugins Custom CSS, Calendar , and Compflight.
B) The strengths of the Custom CSS allows me to customize my blog more, for example I have turned my font into comic sans. The calendar is nice because it allows you to have a calendar on your blog so if you need to know the day you can just check there. Compflight is very useful because it allows you to insert any images you need without having to go to google images as well as putting the image as small, medium, large, or full size.
C) Some of the weaknesses of the Custom CSS is that if you do something and forget how to fix it, your blog could be stuck like that until you get help, for example I don’t remember how to change my font back. The calendar doesn’t really have many weaknesses other then that it isn’t very interactive. Compflights only weaknesses is that it has a limited amount of images in it.
D) Out of all of these I would say that Compflight is the most useful for classes as it makes creating a blog post that requires generic images a lot easier. I also think that Custom CSS is helpful as it allows students to customize their blogs more.
Exploring Quadratic Functions
 Find and write the definition of a quadratic function in words you understand. (use your textbook, google, etc)
Quadratic functions are curves called a parabola, which is a U shape that can face any direction.
 Give an example of a quadratic function and give an example of a function that is NOT a quadratic.
 y = 1x^2+2x+4 is a quadratic function. Y= 2x + 4 is not
 Go to desmos.com and type in the following function:
 Desmos will give you the option of adding “sliders” for or all. Click all. This will allow you to change the values of to see how the graph changes.
 Start with slider values . Describe any symmetry you notice.
The line is identical on both sides of the y axis
 Keep b = c = 0. Change the value of :

 Does the graph open up or open down?
 Does the graph have a maximum point or minimum point?

 Does the graph open up or open down?
 Does the graph have a maximum point or minimum point?

 Is the graph narrow or wide?

 Is the graph narrow or wide
 a) i) Opens down. ii) No. B) Opens up. ii) No C) Graph is wide. D) Graph is narrow.
 We call the maximum or minimum point of a quadratic function the vertex. Complete the following statements:
 When is Positive (positive/negative), the vertex is a Minimum (maximum/minimum)
 When is Negative (positive/negative), the vertex is a Maximum (maximum/minimum)
 Let and Use the slider to change the value of Describe how the graph changes as changes. Y value of the vertex

Roots are the solutions to the quadratic equation. The roots are found by looking at where the curve crosses the x axis (xintercepts).
Adjust the sliders for a, b and c so you can get a curve that just touches the x axis (y=0).
Equation: y = 4x^2
This quadratic equation has ONE solution.
Adjust the sliders so you can get the roots of 0 and 1
Equation: y = 3.4x^2 + 3.4x
This quadratic equation has TWO solution

Rube Goldberg Project Power Tech
So mine and Rok’s Rube Goldberg machine started with a Hotwheels car (Wheel and Axl) knocking a ball off of a screw (Wedge) then the ball rolling down a incline plane and landing in a cup activating a pulley then the cup on the other side of the pulley knocked over a domino which landed on a teeter totter (Lever) which pushed a ball down another incline plane and then the ball when through a screw then the ball knocking over more dominoes then a ball getting knocked over into a cup.
Tech Team Year Reflections
What are some things you have learned and/or tasks you have accomplished this year? (Use videos, pictures, upload materials etc. as evidence of learning in your blog)
So this year in Tech Team I really only had 1 big project which was to make a page for a news paper. The parts of it that were successful was that it was very easy and fun to make using photoshop. Some of the challenging parts was centering images and using the text feature in photoshop as it caused me some issues from time to time. To overcome the challenge of the text feature I started copy and pasting the names instead of writing them out as it was easier that way. To improve on the project I think I would make it more appealing by maybe adding a border to it.
As Riverside continues to immerse itself into innovation and technology, what do you think Riverside can do to provide support and help for teachers and students? (Provide specific examples)
I think that training the teachers in the technology and how to fix stuff would be a lot better for students instead of the students missing class to go to the wave. Or have one or two teachers from each department be well enough informed so that they could help out the teachers or students.
Do you have any feedback or suggestions, as we move forward, that could help the Tech Team meet the needs of our school and staff / be more effective? (Provide specific examples)
I think that if the teachers knew which students in there class were apart of the tech team it could be more effective because they could just have them fix any issues before sending someone to the wave or asking for help from another teacher.
Rube Goldberg Project
 First, we drop the marble into a cut in flag pool noodle. The marble then goes almost straight down and then it curves up and falls on to the next pool noodle. This noodle then drops the marble onto a slanted piece of cardboard which guides the marble on to another set of pool noodles. The noodles roll the marble across the back wall and drops the marble into a tube which then rolls the marble down and dings the bell.
 Point A starts with potential energy and transfers to Kinetic around point B. Point BC goes from kinetic to potential as the marble falls, at point d the energy goes back to potential as the marble falls,FG and GH are examples of kinetic to potential as the marble falls. HI is kinetic to potential as the marble stops, and kinetic to sound as the marble hits the bell.

Racism then vs now
While racism is still around I think that it really isn’t as bad as it once was, because now most racism is just from peoples words and hate speech. While back then it from laws that made black people sit at the back of the bus and other forms of segregation. I also think that the media now tends to exaggerate on certain events to try to make it seem more racist because that’ll get the media more views. As well as now most people who are racist aren’t very smart and are very ignorant, while back then it was common and tended to just be the way things were. The KKK are still around but back then they were far more prominent and did some truly horrible things when now there are laws that prevent them from doing those things and those laws are strongly enforced. Which is why I believe that racism is far less then it was back then.
My Dream Life
Making Babies
1. Include a drawing of your child with as much detail as possible.
2. Include a short description of the traits your child has.
Square face, prominent round chin, curly hair, light brown skin, brown eyes average mouth, pointed nose, round nostrils, and freckles
3. Answer the following questions:
How does the coin flip relate to the probability of inheriting genetic conditions? Because there is a 50% chance you get a trait from the father and a 50% chance of getting a trait from the mother
How does this simulation accurately represent or not represent real life?
This inaccurately represents real life because it was random traits and unreflective of how in real life the baby would have the traits of the parents.
Did you identify any prejudices you might have about what traits you find “desirable”? Where do you think these prejudices come from?
Yes, I think a lot of these came from what looked well with other traits and whether it made the baby ugly or not.
