Slide 1: Introduction
Solubility is an important property of matter. Solubility refers to the ability of a substance to dissolve in another substance.

On the next slide, make an educated guess with your team on which objects are soluble or insoluble than water.  Discussion only.

Soluble- dissolves in water
Insoluble- does not dissolve in water

Slide 4 - Slide

Start by introducing the concepts of solubility and density, providing a brief explanation of their importance.

Slide 2: Solubility
Solubility can be determined by testing if a substance dissolves in a liquid. If it fully dissolves, it is soluble. If it does not dissolve or only partially dissolves, it is insoluble.

Slide 6 - Slide

Explain the process of testing solubility and how to classify substances as soluble or insoluble. Emphasize the importance of observing if a substance fully dissolves or not.

Slide 7 - Slide

Slide 4: Testing for Solubility
To test for solubility, add a small amount of the substance to a liquid and stir. Observe if it dissolves completely or not at all.  If it dissolves completely, it is soluble.   If it does not dissolve, it is insoluble.

Slide 8 - Slide

Explain the practical steps to test for solubility. Instruct students to carefully observe and record the results of their tests.

Slide 6: Conclusion
By testing the solubility of objects, we can better understand their properties and how they interact with other substances.

Slide 11 - Slide

Summarize the key points of the lesson and emphasize the importance of testing solubility and density to gain a deeper understanding of objects.
What does it mean if a substance is insoluble?
A
It changes its physical state when mixed with a liquid.
B
It does not dissolve or only partially dissolves.
C
It becomes highly reactive in the presence of a liquid.
D
It fully dissolves in a liquid.

Slide 12 - Quiz

How can solubility be determined?
A
By heating a substance to its boiling point.
B
By observing the color change of a substance.
C
By measuring the density of a substance.
D
By testing if a substance dissolves in a liquid.
