LENGTH LAB In the length lab i learned a lot about measuring a nd how to do it correctly. I learned a lot about meters,centimeter,and millimeters. I also learned a lot about the minimum scale and maximum error that occurs when measuring,and we measured our locker and found out the length,height,and width.

VOLUME LAB In the volume lab i learned a lot about volume and how it helps us in life. First i Learned the formula VOLUME=LENGTHxWIDTHxHEIGHT then we used it to measure these shapes on a work sheet and i learned a lot in the lesson.

CONCLUSION

IN this lab we took pennies and made a hypothesis that says dose mass have an effect on volume then we took a triple beam balance and measure out the mass by two pennies and up by two until we got to ten and we got different mass measurements. Then we wrote all the results down in the lab note book and we started drawing a a graph then we filled a graduated cylinder with water up to 50 and we put two pennies in and we kept doing that until we got up to ten then the volume was shown and we recorded the data. Then we made a graph of the data and we finished. That is a summary of this lab.

In this lab i did notice a few patterns and trends that occurred. Like first when we where measuring the mass it went up by an estimate of 6 units each time and i thought that was a really cool pattern that occurred when you added more pennies to the balance. Another pattern i found was that when i was finding the water displacement of the pennies it went up by .5 then it went up by 1 and then 2 then 4 each time and i thought that was interesting that it was no perfectly up at another 10 mark line. One more pattern i came across was the way the dots went up on the graph it went up in a very straight line and i thought that was weird cause the numbers were not perfect numbers but they did go up by an estimate of six. Those are some of the patterns i found while doing this lab.

In the results of the lab it supported my hypothesis pretty well i said that the mass of the pennies will be greater than the volume of the pennies and that's pretty much what happened because the mass was more than the volume and it all worked out. The results of this lab was good compared to my hypothesis but it surprised me a little in certain spots. Such as the part were i did the water displacement i thought it would have increased by five but instead it increased by .5 sometimes and even stayed the same but it took a second try to get better results. The lab question was what is the effect of mass on volume, and i figured out the question and yes it dose effect volume to some extent because when we added more pennies to the graduated cylinder there was more weight and mass so the volume increased. Those are some of the results i found and analogized.

__whats the difference?__ thermal energy is the total kinetic of the particles but temperature is the average kinetic energy of the particles thermal equilibrium- there is no change in either objects thermal energy __SETUP ON HAND IN ICE WATER ONE HAND IN HOT WATER__

TUB B IS 20.8 TUB A 21.6 ENERGY FROM THE HAND IN TO THE WATER AND IT FELT COLD RIGHT HAND WATER FROM THE HAND CAUSE IT WAS COLD AND THEN WHEN PUT IN WARMER WATER IT MAKES A HOTTER SENSATION FEELING

BUT HANDS STILL CANT TELL TEMPERATURE

final temperature on of the hot and cold lab the temperature of the mixed water it was 45 degrees Celsius it was not like my hypothesis but are average is pretty much exact but the ice cold water cant be 30 degrees that's room temperature and it cant work we did something wrong?

the average temperature of the hot and cold water was always a little bit higher then our final temperature some energy heated up the air and the Styrofoam cup took some energy but for the most part the average is pretty much right.

so over all what happens when you mix water measure average and next time put a lid on cup and pour fast
