Learning Activity Sheet Earth and Life Science- Grade 11 First Quarter - Week 4 Name of Learner: Kyle Caleb B. Medina Date: 10/09/ 2021 . Section: 11- HOBBES MDL (DIGITIZED) Teacher: LILIANA C. ANOG MELC No: 8 Describe the physical and chemical changes in rocks due to changes in pressure and temperature (metamorphism) MELC No: 9 Compare and contrast the formation of the different types of igneous rocks Activity 1: Igneous Rock Buffet Directions/Instructions: In this activity, you will try to make edible igneous rocks by combining several materials found at home. This will help you understand and apply the effects of environmental factors on a rock formation. Materials: โ chocolate chips/cookies/any biscuits available โ pounded rice Krispies/adobong mani/cornick โ marshmallow (any color) โ chocolate sprinkles/coffee powder โ pan/casserole โ nonplastic plate โ any cooking source Activity Proper: Procedure: 1. Melt the marshmallow and chocolate chips/cookies/any biscuits available at home mixture in two separate pans/casseroles with a slow fire at the same time. 2. After melting, transfer the mixtures in the 2 plates. Place different combinations of pounded rice Krispies/adobong mani/cornick and chocolate sprinkles/coffee powder in each plate. 3. Mix all the contents of the plates and flatten the surface. 4. Let one plate to cool down in room temperature or just place on the table for 10 minutes, while the other plate must be placed in the freezer or in a cooler with ice cubes for 5 minutes. Page 2 of 3 5. After cooling down, slice the rock buffet and observe the characteristics of the mixtures in the two plates. 6. Answer the guide questions. Write answers after each question. Guide Questions: 1. What is the difference between the mixtures in the two pans in terms of hardness? -The one that I've put on the table has quite a bit of hardness and is also kinda squishy at the same time. -The plate that I have left on the Ice cube is kinda solid compared to the first one. 2. How do temperature and time affect the cooling of chocolate and marshmallows? -On my observation, The Ice helped the other plate to dried out fast and for the melted marshmallow and chocolate to mixed. The result of the other one made the cooling longer and resulted in not much hardness. 3. Which plate has more porous spaces in between? Why? Explain your answer. -The plate that is left at the table is the one who has more porous spaces than the other one. It might be because of the condition that the chocolates and marshmallows had experienced more heat than part of being cooled off. 4. From the activity, what type of igneous rock is involved? Explain your answer. -The result of the meltation of the chocolate and marshmallow is kind of similar to a rock named "Scoria. The rock scoria has a dark reddish color which is kinda similar to the color of the chocolate I've melted, and it also has porous spaces that is also a similarity to the result of my experiment on the plate I've cooled down from cube ice. The process that had formed the rock scoria is also similar from the procedure I've done on my experiment. Scoria rock and my experiment had both traversed through conditions of extreme heat and were both also immediately cooled off by water and ice substances. Most of the igneous rocks are used in the construction of buildings, houses, malls, parks and many more. a. What are the common igneous rocks being used for construction? -Granite. b. What are the common uses of igneous rocks in constructions? -Igneous rocks are use as materials for building concrete walls, buildings, and statues. c. Why do you think igneous rocks are being used for this purpose? -Because the toughness it has to the point that it can withstand rough Weather and such erosion.
