this week in science we kept on practicing with the formulas that we know to find speed on a graph. what we have learned is that in order to find the speed of jsomething on a graph you have to get the dealta positon which is what was the change of position over time then you have to divide that by delta time which is the change of time. for example if you had a 35 positoion change and a 75 time change then you have to divide 35 by 75 which is .47 is your speed. at the end of the week we had a quiz on all that we wree learning about this then the week eneded.

this week in science we got proposed a new question from mr.segan and mr. finley. it was if we had a slow car and we had a fast car and we put them a few meters a away from each other, we would have to find out at what positoion are they going to hit. the experiment that my rable came up with was: we are going to do the same thing as we did with the walking experiment and find how many meters per seconds each car moves. after we get that info we can plot that on a chart and see where each one itrelocks which in real life would be were they crash. after we are done with the prediction we will go on test if the graph mathches the car in real life. my tables results was for the slow car it moved 7.13 seconeds per meter and for the fast car it moved 3.37 seconeds per meter. after that we thiiught it wwould be eaiser if we found out how far they would go in one minute so for the fast car it went .16 meters in one seconed. after we graphed the info we saw that they were going to crash at 13.43 seconed and four meters after we tested it out we saw that it was pretty close to what we predicted so the other time that was off was probably just a confounding variable.

this week in science was short but we still did a lot of things. well earned how to find they speed of something by just looking at a graph. you cant always give mph but you could give meter per second or even meters per hour ect... another thing that we learned how to do is finding the slope of the trend line, and also we learned that the speed and the slope are the same thing. we also learned hoe to write functions that represents tables or graphs. the function is like the pattern of time and position then you just write it out like, x(+)=2(m/s)-t that's a function. that wraps it up.

this week in science we learned how to draw create and plot data on a graph and table. the things that we learned about graphs were when the line on a line graph curves down or up, if it curves up it is accelerating or going faster because it is traveling more distance per time unit. if it curves down then it is going slower because it is traveling less distance per time unit. if the line goes straight across the graph then it is not moving at all. the other time that we learned is that when something slowes down it moves horizontal.and for tables there is not that much to know or learn. thats it, peace.
