SCIENCE7: Types of Mixtures

This will really help students in knowing Types of Mixtures. It has examples, explanations, exercises and activities.

1. 11/27/2020 1 SCIENCE 7 TYPES OF MIXTURES

2. MELC #3 : Distinguish mixtures from substances based on a set of properties. Quarter : 1 Week : 4 OBJECTIVES : Identifies the two types of mixture; Differentiates the two types of mixture; Performs an experiment about mixture; and Appreciates the importance of mixtures in our everyday lives .

3. MATTER Anything that occupies space and has mass. MIXTURES Is a combination of two or more substances that are not chemically combined. PURE SUBSTANCES Is a substance that are made of only one type of atom or only one type of molecule. LET’S HAVE A RECAP…

4. QUESTIONS: LET’S OBSERVE… What have you observed in the picture? 2. What is the difference between the two pictures? 3. Which picture shows a homogeneous mixture? 4. How about heterogeneous mixture?

5. MIXTURE It is made up of two or more substances that are not chemically combined with each other. The components of a mixture retains its own identity and properties. The separation of components can be easily done. Mixtures are classified based on how uniform they are and on the particle size of components relative to each other.

6. HOMOGENEOUS HETEROGENEOUS MIXTURE

7. HOMOGENOUS MIXTURE A mixture in which the components are evenly distributed throughout and has a uniform appearance.  + =

8. A mixture in which the components are not evenly distributed throughout. Heterogeneous mixtures possess different properties and compositions in various parts. The properties are not uniform throughout the mixture. HETEROGENOUS MIXTURE + =

9. HOMOGENEOUS MIXTURE HETEROGENEOUS MIXTURE 1. Have a uniform composition throughout the mixture. 1. Have a mixed composition which may vary from point to point. 2. Components are not visible to the naked eye. 2. Components can be seen easily. 3. The whole mixture is in the same phase. 3. Substances can be of two phases and layers may separate. 4. Particles size is often at atomic or molecular level. 4. Have large particle sizes. 5. Components cannot be separated easily. 5. Components can be separated easily.

10. HOMOGENEOUS MIXTURE Can you guess which one is homogenous or heterogenous? HETEROGENEOUS MIXTURE HETEROGENEOUS MIXTURE

11. HOMOGENEOUS MIXTURE HETEROGENEOUS MIXTURE HOMOGENEOUS MIXTURE

12. HOMOGENEOUS MIXTURE HETEROGENEOUS MIXTURE 1. Milk and Cereals  2. Soft drinks 3. Smoke 4. Cup Noodles 5. Fruit salad I. IDENTIFICATION. Identify the following substances and mixtures as either homogeneous or heterogeneous.  LET’S WRAP IT UP…     LET’S BRING IT HOME: Study in advance on Saturated and Unsaturated solutions.

13. ONLINE/MODULAR : For online, attach and submit your video on Friday, October 2, 2020 @ 02:00 PM to Google Classroom. LET’S DEEPEN MORE For modular, write your answer on a short bondpaper and submit your answer on Tuesday, October 6, 2020 @ 08:00 – 04:00 PM here in school. September 28, 2020 LET’S WORK IT OUT… 1. TASK: Using a recorded video, perform a simple experiment emphasizing the difference of homogeneous and heterogenous mixture. Explain what makes it homogeneous or heterogeneous. (50 points) 2. TASK: Using available materials at home, list down at least three materials each showing a homogeneous or heterogenous mixtures. Explain what makes it homogeneous or heterogeneous. (50 points)
