march 8

ok im very sorry i havent written in a long time. but going to this week in science we stared a physics unit. it is very confusing but i kind of understand it. the defininiton of physics:The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics. weve done many exparments for example:

1) we took a basketball and brenna had to look at the ball an donly the ball and walk at the same speen as vinyy who was holding the ball. we found out that if you look at a objet and only the object and move at the sam espeen its moving the object will look stationary.

2) we had a toy car and we hada counter whos had to count the time in seconds the car would run and the counter would say the seconds that passed by. in my gruope we did every two seconds. so every 2 seconds vinny who was the marker would mark the distance the car travled in 2 sec. in the end we found out that some times an object can move faster towards the end or go slower.
i have the work sheet so when i fingure out how to scan i will scan it on the my blog i promis.
