3. PROPERTIES OF SOLUTIONS

4. At the end of the activity, the students should be able to: compare the evidence gathered with the predictions you made; and describe the properties of solutions based on observations 4

5. 5 Sample solid or liquid Will dissolve in one cup of water ( Yes or No ) Appearance Number of phases Can be separated by filtration ( yes or no ) Solution or not a solution sugar           salt           mongo seeds           powdered juice           cooking oil           vinegar          

6. Describe the mixture that resulted after mixing. Write your answer in column 3. How many phases do you observe? Write your answer and observations in column 4. Identify the solute in each of the mixtures. Write your answers in the blank: ________________ What is the solvent in each of the mixtures? __________________ In which mixture were you able to separate the components (solute and solvent) by filtration? Write your observations in column 5 of Table 1. Which of the samples are solutions? Write your answer in column 6 Answer the Guide Questions: 6

8. Activity 2 Each group will cite 4 examples of solutions. A representative from the group will explain each solution with their component and properties in front of the class. Explain also the value of solutions in our lives. The group who will got the highest score will be given a reward. 8
