22 questions
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.
1

When Maya mixed sugar and water, Maya said "The sugar disappeared." Did the sugar disappear?

1

After leaving a sugar and water mixture by the window for a few days, what did Maya observe in the cup?

0

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

1

Are the sugar molecules attracted or not attracted to water molecules?

1

Does this model show sugar dissolves or not dissolve in water?

0

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.

1

Is sugar soluble or not soluble?

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

1

Are the cinnamon molecules attracted or not attracted to water molecules?

1

Does this model show cinnamon dissolves or not dissolve in water?

0

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 ____________

1

Is cinnamon soluble or not soluble?

Choose “soluble” if the solid will dissolve in the liquid. Choose “not soluble” if the solid will not dissolve in the liquid.
1

Pepper and water

1

Citric acid and water

1

Cumin and water

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.

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

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
