If you need to review information from the lesson, watch the video below.
You should have read the book for homework. Answer the following questions.
Question 1
1.

Question 2
2.

Question 3
3.

Why did it look like the sugar "disappeared" when it was mixed with water? What happened to the sugar?

Discussing Solubility
These are models that Diego used to help Maya make inferences about sugar, cinnamon, and water molecules.
Use the information the Sugar and Water Model to answer the questions below

Question 4
4.

Question 5
5.

Question 6
6.

How do you know (explain your answer)? Use evidence from what you see in the Sugar and Water Model.

Sentence starter: In the model, it shows ____________

Another way to say that sugar can dissolve is to say that sugar is soluble in water.

Question 7
7.

Use the information the Cinnamon and Water Model to answer the questions below

Question 8
8.

Question 9
9.

Question 10
10.

How do you know (explain your answer)? Use evidence from what you see in the Cinnamon and Water Model.

Sentence starter: In the model, it shows ____________

Question 11
11.

Choose “soluble” if the solid will dissolve in the liquid. Choose “not soluble” if the solid will not dissolve in the liquid.
Question 12
12.

Question 13
13.

Question 14
14.

Modeling Dissolving
Just like Diego in the book Solving Dissolving, explaining and understanding the concept of dissolving requires the use of visuals and language. We’ll create nanovision models of dissolving.
Question 15
15.

Model 1 – Dissolving (Soluble Solid)
  • Use the MM 2.3-2.4 Dissolving Models document on google classroom
  • Follow the directions on google classroom
  • Take a screenshot of your Model 1 – Dissolving (Soluble Solid) Model
  • Add the picture of your in “Show Your Work” on goformative

Question 16
16.

Model 2 – NOT Dissolving (Not Soluble Solid)
  • Use the MM 2.3-2.4 Dissolving Models document on google classroom
  • Follow the directions on google classroom
  • Take a screenshot of your Model 2 – NOT Dissolving (Not Soluble Solid) Model
  • Add the picture of your in “Show Your Work” on goformative

Writing a Scientific Explanation (Paragraph)

Write a CER (Claim / Evidence / Reasoning) paragraph to answer the question below.

Question: Which flavor ingredients will not leave sediments in the salad dressing?
Question 17
17.

Write your CLAIM (Answer to the question)

Sentence starter: The flavor ingredients that will not leave sediment are ______________ and _________________

Use the following sources of evidence to support your answer

Question 18
18.
