Upload pictures of your 4.1 lab dye observations and their Rf values.
Question 2
2.
Upload a picture of your 4.1 lab CER.
Question 3
3.
Take a picture of your 4.2 simulation responses here
Question 4
4.
Take pictures of both your 4.2 science talk preparation AND your participation feedback from your partner.
If you didn't receive feedback from a partner- record that in the space. Also, if you had a role during the science talk record that here too.
Question 5
5.
Use your science talk feedback to explain what is 1 area that you did well during the science talk? What is 1 area you can improve?
(If you didn't get feedback, you can do a self-assessment)
Question 6
6.
Take a picture of your 4.3 making models activity from your NB or upload your responses from Google Drive
Note: If you copy and paste a link, please make sure you share the document with both teachers to view (jmayorga@stem-prep.org and ozamarripa@stem-prep.org)
Question 7

Click on show your work and complete the table. There is an example for the 1st one.
Here is a help video from the 4.3 pear deck that goes through how to complete these questions
4.4-4.7 Polarity and Intermolecular Forces
PS2-6: intermolecular forces of attraction
Question 8
8.
Take a picture of your 4.5 Properties of substances lab analysis questions 2-4 poster.
Lab template
Sample lab data
Question 9
9.
What different shapes do you notice among the 3 dyes? How might different shapes within a larger molecule explain how attractive a dye will be to a t-shirt? Hint: Look at the different types of atoms and shapes coming off of the rings
Question 10
10.
Use the shapes you noticed to describe polar and nonpolar parts of each molecule. How would each dye interact with water versus paper? Hint: Determine the polarity of water and paper given and think about how each dye would interact with both.
Water
Paper
Question 11
11.
1) Add a picture of your polarity group poster from the 4.7 slide deck.
2) Take a picture of your science talk feedback. If you did not receive feedback then write that in the text or as a comment.
Question 12
12.
Use both shapes and polarity to explain which dye to avoid for our summer t-shirt collection. Explain whether you would expect this dye to have stronger or weaker forces of attraction to water versus the other two dyes and why that dye might not stay after several washes.
Water
Paper
