Today we came in and turned in our homework "Nuclear read and react". (The one where we wrote a paragraph on the back) We Coats-Haan couldn't get us to focus and get on to the notes she introduced herself and went around and shook everyones hand. Then we looked at our other homework and texted in our results for #of mrem/yr. We moved on to atomic notes, in which we started to learn about different parts of protons and neutrons. We have no homework tonight! Our next quiz is on 5/7
also Coats-Haan kept saying "Neato"
QOD - Gravitational force- this witch was large, representing the fact that gravitation force is based on mass. this witch was also floating away representing the fact that it isn't very strong.
Strong Nuclear- this witch was a woman of color. I don't remember why exactly, it had something to do with the particles having color?
Electromagnetic and Weak Nuclear- electromagnetic had a stick that looked like it had electricity going through it, also she looked much meaner than the others. This is because she is the one that causes pain. Then the weak nuclear witch looks like she could be the same witch a electromagnetic, she is just hiding in a doorway in shadow. They look similar because now there is evidence that they may be 2 different forms of the same force

Today in class we were given the option to finish up the Camera Lab or work on the test review. We were, however, interrupted by a fire drill (a brief description of our exit route: exit to the right of the room and proceed towards the emergency exit staircase. Without talking please continue toward the bleachers of the track field and line up for attendance). When we returned to our room, we began working. The class was really calm and basically we got to work on whichever work we needed to.

QOD: Nothing can travel faster than the speed of light and “n” is the denominator in determining the speed so it cannot be less than one, in turn calculating a speed greater than 3x10⁸.
