HONORS CHEMISTRY – Happy use your brain day!! Can you now use what you’ve learned about density? Who is going to be your spokesperson? When is your lab going to be due? Do you need two due dates???
Can’t wait to “watch” you work!
Hon Chemistry 9-6-22 ID of Unknown Lab
clear average is 1.48 g/cm^3
actually 0.81 g/cm^3
i believe the clear blocks are gamma
My Milky block
Width=3.9 cm
Length=6.6 cm
Height=2.6 cm
Volume=LxWxH
V=6.6 cm x 3.9 cm x 2.6 cm
Volume= 66.9 cm^3
Mass= 59.6 g
D=m/V
D= 59.6 g/ 66.9 cm^3
D= 0.890 g/cm^3
Color Black
V=l^3
V= 12.20cm * 4.15cm * 1.30cm
V= 65.82cm^3
m= 65.96g
D= m/V
D= 65.96g/ 65.82cm^3
D=1.00 g/cm^3
Averaged Density= 0.99 g / cm^3
Block name Beta
Milky
Width-7.32cm
Height-1.25cm
Length-4.50cm
Volume= l x w x h
Volume=(4.50cm)x(7.32cm)x(1.25cm)
Volume- 41.175cm^3
Mass=36.60g
Density=Mass/volume
Density=36.60g/41.175cm^3=0.889g/cm^3
Density=0.889g/cm^3
The milky group have an average of .910 g/cm^3, which matches perfectly with the Delta block name.
1.14 g/cm^3 average for clear
so we’re done?
thanks sydney
should we do uncertainty?
Moriah, ask her if we need to keep the sheets
I can do the average for the paper white blocks?

I’m guessing white is Alpha?

(l=7.60cm; w=8.25cm; h=1.30cm—ruler)
V=lwh
V= 81.51cm^3

D=0.97g/cm^3
2) olivias block:

3) Jackson’s block:

V=lwh
V=65.82cm^3

D=1.00g/cm3
Average: 0.97g/cm^3 + 1.00g/cm^3 + 1.00g/cm^3 = 2.97g/cm^3
2.97g/cm^3/3 = 0.99g/cm^3
Manning, Jackson Reeves, and I think that the average of the density of our block (0.99 g/cm^3) is closest to the density of Beta (0.967g/cm^3).
has anybody averaged the gray block
Milky
L- 10.4 cm

Are any other groups getting blocks very accurate to the correct value
WITHOUT averaging?
my clear block has:

Moriah, check this
ALPHA-white
BETA-black
DELTA-milky
GAMMA-clear
EPSILON-grey
everybody respond if they agree with their placement. I agree
i have that down
I agree with lindsay

This week I finished the coin mass lab. I struggled with it at first because I couldn’t balance the ruler, but I eventually got it to balance and finished my project. I give myself a 4.
This week I was able to stay on top of homework assignments by using kahoots, quizlets, and class group chats in order to fully take advantage of the tools and resources that are open to me. This is so I can be better prepared for class and future tests. Based on this reflection, I give myself a 3 out of 5 because there are still things I could have done better.
I would give myself four stars for this week. I was pleased, but frustrated, with my test this week. I was pleased with the grade, but I was mad at my careless mistake that led to me not getting the better grade. Additionally, I was pleased at the class’ ability during the Lab of Unknowns to communicate and calculate without speaking. Next test I will use my time more wisely, so that I could help eliminate careless errors.
For this week, I would rate myself 3/5 stars. This week I stayed on top of my work, but was still a little lazy for most of the week. This was mostly due to the three day weekend. I did, however, run further than I ever have in my life, which is something I guess.
This week has been three out of five stars for me. While I may have not gotten the grade I wanted to on my test. I know that I did the best of my ability. From this I have learned for the future a better way to study and take a test.
I would give myself three out of five stars for this week. I was happy with the way I worked hard to study and finish all my assignments while also having after school activities. I didn’t do as good as I wanted to on certain tests/quizzes, but I learned how to better prepare for them in the future by studying a different way. Next time I will try other studying methods as well as focusing on my work!
This week, I would rate myself a 4/5. I did very well on my test, but looking at my mistakes, most of them were careless. I was frustrated at how I could’ve scored higher but was proud of myself for getting an A on the first test.
This week I rate myself four out five. I was happy with my grade on the test, but I could have done better if I didn’t make careless mistakes. I was also happy with how well the class worked together on the ID of Unknowns lab.
This week I’d rate myself a 4/5. I was happy with the way i studied for the test but I made careless mistakes on the test that held me back from getting a much better grade on the test. I think one solution for this could be to practice with time management, as time was the reason I wasn’t able to go back and check over my work and answers like I do on most tests.
