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!

Mass of my block (clear)- 59.382 g
Volume of my block- 10.48cm x 3.90cm x 1.22 cm= 49.86cm^3
Density of my block- D=m/V, or D=59.382g/ 49.86cm^3 or D=1.19 g/cm^3
Therefore, my block is Gamma (1.17 g/cm^3)
i had the gray block. my mass was 87.752 g, the volume was 59.8 cm cubed (length equals 8.3 cm, width equals 6 cm, and height equals 1.2 cm), and finally i got the density of 1.47 g/cm cubed. in conclusion my block was epsilon.

Mass= 65.149g
V=lxwxh
V=5.76cmx4.81cmx2.59cm
V=71.76cm^3
D=m/V
D=65.149g/71.76cm^3

I got a milky white block with the density of 1.1g/cm^3.
V=lxwxh=7.0cmx4.3cmx1.1cm=33.11cm^3
m=36.55g
D=m/v=36.55g/33.11cm^3=1.1g/cm^3
I had the Black block which is Beta. I found the
Volume=lxwxh as
V=12.68 cm x 4.11 cm x 1.24 cm
V= 64.6 cm^3
Then I found the mass as
mass= 65.842 g
And I know Density= m/V so
D= 65.842 g/64.6 cm^3
D= 1.018 g/cm^3 and we need to round so
D= 1.02 g/cm^3
Paper White:
Mass (m) = 38.455 g
Volume (V) = l x w x h
l = 8.75 cm
w = 4.19 cm
h = 1.81 cm
V = (8.75 cm) (4.19 cm) (1.81 cm)
V = 66.359125 cm3
D = m/V
D = 38.455 g/ 66.359125 cm3
D = 0.579498298 g/cm3
D = 0.579 g/cm3
Based on my data, I can conclude that I have the Alpha block.
Mass of my Block (clear)- 99.768 g
Volume of my Block- 83.125 cm^3
V=lxvxh
Density=1.20021654 g/cm^3
D=1.20 g/cm^3
D= m/V
The clear block is Gamma.
Gray Block
mass = 77.865g
Length = 7.11cm
height = 1.12cm
width = 6.45cm
Volume = V=lxwxh
7.11cm x 1.12cm x 6.45cm = 48.7cm^3
D=m/V
77.865g/48.7cm^3 = 1.60 g/cm3
Gray block = Epsilon
Gray Block:
m= 95.112 g
l= 10.13 cm
w= 5.36 cm
h= 1.21 cm
V= l x w x h
V= (10.13 cm)(5.36 cm)(1.21 cm)
V= 65.7 cm^3
D= m/V
D= 95.112 g/65.7 cm^3
D= 1.45 g/cm^3
Black block:
mass of the block=110.40g

The black block’s name is Beta.
Gray Block:

I had a milky white block.
V=l x w x h= 7.00cm x 4.30cm x 1.10= 33.11cm^3
m=36.550g
D=m/V=36.550g/ 33.11cm^3=1.10
Paper White which is alpha
Mass of block: 40.890g

V=lxwxh
V=(9.31cm)x(1.31 cm)x(6.90 cm)
V= 84.153 g/cm^3
D=m/v
D=40.890g/84.15309cm^3
D=0.486 g/dcm^3
I had a milky white block.
V=l x w x h= 7.00cm x 4.30cm x 1.10= 33.11cm^3
m=36.550g
D=m/V=36.550g/ 33.11cm^3=1.10g/cm^3
This week I would give myself a 3. I am giving myself a 3 because the lab we did on Tuesday confused me at first, but once I got the hang of it I was alright. And for some reason got a density that was different from the sheet, so I knew that was my bad. But overall, I think this week was a pretty good week in chemistry.
I’d give myself a 4 out of 5 on the Zooniverse activity we did on Wednesday. I thought it was super interesting and fun. Plus, I really like being able to use what we’ve learned in Chemistry to help move along actual scientific research! But I wouldn’t put a five because I still struggled to do parts of the research. But I look forward to getting on the website again.
Rate- I would rate my week a 4 out of 5 stars so far. I ended up doing better on my test than previously expected. I’ve learned how stressing out too much over a test can mess things up.
Rate: I rate myself 4 stars out of 5. I did way better on my test than I expected, but I am still confused about one problem. I studied pretty thoroughly, and I’ve learned to work on more big extra mama large problems when studying.
Reflection/ Rate: I would give myself a rating of 4 stars out of 5 this week. I would rate myself this because I worked really hard studying for the test last week, and it payed off. I didn’t give myself five stars because I made mistakes that could have been avoided, and I know there is always room to improve my problem solving skills.
Rate: I rate myself 4 out of 5 stars this week. I give myself a 4 because of the lab we did on Tuesday. I was definitely confused since the whole class was a group, and we could not verbally communicate with each other. As soon as I texted my classmates and figured out what I was supposed to do, I got the hang of it!
