# Detailed lesson plan science

Look/observe the materials in the picture Can you separate the mixture of cement, gravel and sand? Yes madam we can. Can you give other materials that form mixture? Yes, Madam. What are those materials that form mixture? The food we are eating. Example: fruit Salsas, pinkest,pickles and others.

Very good! Our lesson for today has something to do with your given example about mixture. What is mixture? Substances put together. The other Ways of Separating Mixture are: Mixture contains two or more 1. Evaporation-salt forms the seawater.

We separate salt from the seawater. By the process of evaporation.

2. Filtration-we can separate substance from a by filtering out undisclosed materials from the mixture. 3. Sieving-a sieve is made of a wooden or metal frame. 4.

Straining-ex. Coconut milk can be extracted from the granted meat by straining. 5. Winnowing-separating the chaff from the rice grains by wind. 6.

Sifting-the example of missing a magnet is the activity of group 3. 7. Using a magnet-the example of missing a magnet is the activity of group 3. 3. Developmental Activities A.

Activity Proper Divide the class into 3 groups each group works on the Activity chart assigned to them. Group 1- Activity 1 Material: Stone of different sizes, sand, muddy water, Jar, cover for the Jar, another empty Jar Procedure: Punch small holes in the Jar cover. Place the following materials in the Jar in this order to serve as a filter: big stones, small stones, and sand. Pour the water into the Jar. Turn the Jar upside down. Allow the water to filter into another container.

Observe. Question: 1. What materials are left inside the Jar? 2. What materials pass through the holes?

Materials: mongo, seeds, Jar and rice Procedure: Mix the rice and mongo seeds in Jar shake the Jar in all directions. Question: Can you separate the mix of rice and mongo seeds? How? Group 2-Activity 2 Materials: 3 small mineral water bottles, salt, sand, Get 3 small mineral water bottles.

Put equal amounts of salt and sand in two of the water bottles. Pour these into third water bottle and shake it thoroughly. Question: Where you able to separate the salt from the sand Materials: cheesecloth, glass, sand and water water. Procedure: Get a scoop of sand and a glass of water.

Mix the sand and Pass the mixture through cheesecloth.

Question: How does the water separate from the sand? Group 3- Activity 3 Materials: stones, sand, soil, water, 2 Jar, cover for the Jar Put the stones of different sizes, sand, and soil. Pour clear water (not pond water) inside the Jar and cover it. Shake the Jar well until the sand, stones, fine dust, and clear water are mixed. Set the Jar down and watch the mixture settle 1 . How did the mixture appear afterwards? 2.

Which materials settled at the bottom? 3. Which materials stayed on top? 4.

Which materials did not separate from the water? Materials: Magnet, iron fillings and flour Procedure: Get your iron filings. Mix them with flour. Hold a magnet over the mixture. Observe what happens.

Question: Can you separate the mix of iron filings with flour? B. Generalization What are the different ways of separating mixture? Filtration, Sieving Straining, Winnowing, Sifting and Evaporation, Using a magnet How can you separate the coins from the sand? Coins in the sand By picking up of the How can you separate the chaff from the rice grains? By winnowing in the wind

How can you separate the grated coconut from the grated meat? Using straining c. Valuing: Showing safety precaution in doing experiments, should you be experiments? Why? IV. Evaluation: Direction: Match Column A with Column B. Write the letter only.

1. Refining flour using a sifting. Separating materials by heating. Separating UN-dissolved solid materials in a mixture. Separating the chaff from the grains by wind.

Separating pebbles from the sand using a wire screen.
