Like the Eighth grade, we also change gears and turn to Physical Science. We focus on Physics and begin with Motion and Forces
What is position?
What is motion?
How are both measured?
We also want to be finding interesting experiments in physics. Why are they important and how do they tie in with what we are covering? To help get the ball rolling we will look at some great discoveries and experiments throughout history in the Science Channel's presentation of 100 Greatest Discoveries: Physics.
This weeks contract has you designing a lab, demonstration, inquiry that teaches us about position or motion. The best presentations will be done by both classroom groups on lab days(Wednesdays).
you meausure motion by time, location, speed, and acceleration
ReplyDeletewhy do we want to know about physics? what impact will it have in our future
ReplyDeleteWhat are the differences between position and motion?
ReplyDeleteHow did people come up with all these formulas for motion, acceleration, speed, ect.?
ReplyDeletehow are motion and speed diff.
ReplyDeleteWhy do things accelerate?
ReplyDeleteok i was trying to find out how to make purple smoke but aperenty that makes a bome so instead i found a really cool experemient on youtube on making marshmellows (well it says marshmellow but idk if it really is) it is cool. you take hydrogen preoxide + liquid soup + potassium iodide = a type of marshmellow. but idk how this happens yet. just paste the link bellow in a serch engine and watch

Position- where something is in reference to another, use reference points and latitude and longitude
ReplyDeleteMotion- change of position, measure by distance in meters
Motion is a series of potions put together to create movement.
ReplyDeletePosition= a location compared to another location. You can measure this by using reference points and longitude and latitude and also using meters.
ReplyDeleteMotion= a change of position over a period of time. you can measure this by usng meters.
y do we do meters per second instead of miles per hour?
ReplyDeletemotion is changing potitions, speed is how fast you are going
ReplyDeletewe run 10 miles an hour how can we mesure this time
