Science this week

Well this week in science we did not do many things. We just went according to the packet that we have all the Kinematics questions in. We did learn something new about velocity arrows. This is the same thing as the dot diagram or the motion diagram except this has arrows to show which direction that the object of measure is traveling in. Mark, Chris and i did a lab on how to measure the distance traveled when we hit a basketball with a hammer. We found we created a graph ob it and we were able to conclude that the basket ball starts off at a fast speed, then slows down constantly over a long period of time. Then on Friday, we had a partner quiz on all the things that we had learnt. We were supposed to make a graph on how fast somethings was going. And, that concluded our week in science

This is important for us to learn so we know how to calculate speeds pf things later in life if we are talking a physics career.

Science in school this week

this week in science, We only did tings about lab report on how we could find the normal speed that our object was moving at.

Our objective was to locate where in six meters would a fast car and a slow car, we took the speed of the fast car by measuring how long it took the car to travel six meters, then we divided the six meters by the seconds the time that it took the car to accomplish the six meters. The equation that we used was: Change in Position

Change in time

So, the fast car's speed came out to be 14.56 seconds over the distance of 6 meters.

The slow car's speed came out to be 27.6 seconds over 6 meters.

The fast car's speed came out to be 0.411 meters/seconds

The slow car's speed was 0.22 meters/seconds

Thats almost half the speed of the the fast car's speed.

So, we predicted that the the crash between the two cars shall take place somewhere in the six meters closer to the slow car.

Before we did this in class, we learnt what a slope was. It is the same thing as the speed. You calculate the slope by taking one point of the position and subtract the second point from the first point. Then divide that by the first point's time and subtract the second points time.

cow eyes!!!

i didn't blog when we did the cow eyes because i had the flu and was out on the Wednesday. The cow eye dissection was very important because that showed us how the eye works and how it lets the light pass through the eye causing us to see This is very important because we should know how our eyes use refraction to let us see and how the principals of light are applied to how we see.

We got to see some of the following parts in the cow's eye:

1. Retina
2. Optic nerve
3. lens
4. Iris
5. pupil
6. Cornea
7. Optic disk

It was pretty cool.

what i learnt was that the light would enter the eye and refract in the Aqueos Humerous and go through the pupil and refract in the lens and goes to the retina and casts the picture of what the light bounced off of and thats how we see.

A three day week in science

This week, we only had three days to learn things in science. On Monday, we took a partner quiz reviewing a lot of things of that happened in science to make sure that we remembered those things.

Trend lines

According to my understanding, A trend line doesn't have to exactly fit the dots that were placed on the graph because it shows how much uncertainty is in the results on the graph.

The black trend line shows that the results could have been according to the path of the line and no the results displayed on the graph.

On Wednesday, we discussed or homework which is about functions or equations to help create an index. this is an example function like we got in our home work.

Bob starts at t1 hours and reaches her destination at t2 hours at a position h1 and reached a position of h2, our function would be... t2-t1*h2-h1.

This is important to us because functions help us calculate complex things that we will need for jobs like rocket science and professions in math.

science on the week of halloween

this week in science, i was sick from the flu until thursday:

On thursday, i had no clue what was going on.

we talked about how an index works. this is the most simplified ratio when making a ratio on a quantitative observation.

We use index making when there is something moving per a time measure.

suppose a pop corn machine makes 10 corns in the period of 7 seconds. This is a ration of how it looks before simplification

10/7=?/1

so, we divide the ten by seven and get 1.428.

that was the rate of how many kernels were popped in one second. this is a simplified index.

This is important to us because we should be able to know how to calculate simplified ratios for different rates.
