Solutions: The Homogeneous Mixtures : An Online Treasure Hunt for 3rd Year High School (Science)

Authored by P. Mosquite and P. Arinto

Sugar melting into your coffee. Powdered juice dissolving in water. Soap being washed away from your body. Your dirty clothes being washed clean.

These are examples of solutions being formed or produced. What is a solution? What are its components, properties, types? We will find out in this online treasure hunt. After working on this activity, you should be able to recognize solutions around you and appreciate their value.

The activity is simple. Working in groups of three or four, answer the questions below by reading the websites listed (under “Resources”). Note that the websites are not arranged the same way the questions are arranged. Read the questions, click on the website URLS, and read the websites carefully. Write down your answers neatly and be ready to discuss them in class. And then proceed to answer the Big Question.


  1. What are the components of a solution? Give an example of each.
  2. Why are solutions called homogeneous mixtures?
  3. Describe the changes that occur in the process of solution formation. Or what happens when the solvent and solute get together?
  4. What factors affect solubility?
  5. What term is used to describe liquids that do not dissolve in each other (for example, oil and water)?
  6. List down the differences among saturated, unsaturated, and supersaturated solutions.
  7. What are the colligative properties of a solution? What do these properties have in common or why are they grouped as “colligative”?
  8. What is the difference between molarity and molality?

The Big Question
Look around you (your house, school, market, etc.) and see how many solutions you can find. Identify the solvents and solutes in each solution. If you can, determine the concentration of the solute (sometimes this is indicated in the container).
Present your answers in the form of a table, thus:

Name of the Solution Solvent Solute Amount of Solute (Concentration)

Do this activity as a group—that is, the same group that did the online treasure hunt. Make sure everybody contributes to the list. You will get one point for every correct item in every column of the table. This means the more correct items, the higher your score.
Submit your table (with the names of group members please) tomorrow. Happy hunting for solutions!
