DISSOLVING MODEL FROM THE SIMULATION
💚 Is this a model of a solid that has dissolved in a liquid? Or is this a model of a solid that didn’t dissolve in a liquid?
💚 Explain your answer for question 2
This model shows ________________________
DISSOLVING MODEL FROM “SOLVING DISSOLVING”
💚 Is this a model of a solid that has dissolved in a liquid?
Or is this a model of a solid that didn’t dissolve in a liquid?
💚 Explain your answer for question 4
This model shows ________________________
Nanoscale - Things to small to see, atoms and molecules
What do you see in the model?
Observable scale - What we can see with our eyes.
What do you see when sugar and water are mixed together?
How is this model similar to the model we just looked at? How is it different?
💚 What do these models show on the nanoscale that can help explain what you see on an observable scale?
Use both sentence starters:
On the nanoscale I see ______________________________
This is why on the observable scale I see ______________________________
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.

Explain why this happened (at the nanoscale).
💚 Which mixture shows something dissolving?
💚 How do you know the mixture is dissolving? (What do you see?)
💚 Why is the cumin not soluble in mixture 2?
