Name: __________________________________________ Grade/Section: ___________________________________ Date: ___________________ Score: __________________ Volcano Model and Volcanic Eruption (EARTH SCIENCE) Most Essential Learning Competencies: The learner shall be able to: describe the different types of volcanoes and volcanic eruptions, explain what happens when volcanoes erupt; and illustrate how energy from volcanoes may be tapped for human use. Objectives: Create a model of volcano using basic tools and ingredients. Illustrate the process involved in volcanic eruption. Compare and contrast the volcanic eruptions produced by different substances Materials: For the Volcanic Eruption 2 tablespoon of baking soda 2 teaspoon of yeast 6mL of liquid detergent 5pcs. of Mentos candy 1 bottle coke (small) ½ cup hydrogen peroxide (Available in Science Lab) Food coloring (red or orange) Stirring rod (Available in Science Lab) For the Volcanic Model Let the students think of the materials they want to use in order to make a volcanic model. Safety precautions: Wear protective clothing such as safety googles, lab aprons or coats, and protective gloves. Read through the instructions first and prepare the materials needed before starting the activity. Follow verbal and written instructions carefully. If you are unsure about any part of the activity, ask your teacher before taking any action. Handle chemicals, glassware, and equipment with care. Do not stiff or taste any chemicals or substances. Keep your work area neat and tidy at all times. Page | 1 Procedure: For the Volcanic Eruption 1. Using the stirring rod, mix ¼ cup water, 1 tablespoon baking soda, 6mL liquid detergent, and three drops of food coloring in a cup. 2. Pour the prepared mixture into the mouth of your volcano. 3. Slowly pour vinegar into the bottle and watch how furious your volcano is. Record your observations. 4. Clean area for another experiment. 5. Repeat step 1. 6. Put 5 mentos candy inside the volcano and slowly pour 1 bottle of coke. 7. Repeat step 4. 8. Add yeast into the mouth of volcano. 9. Mix 20mL cup of hydrogen peroxide and food coloring. 10. Pour hydrogen peroxide into the mouth of your volcano. Data and Results: Substances involved Duration of Eruptions Height of eruption (cm) Distance of lava flow from the mouth Other observations 1. Vinegar 2. Coke 3. Hydrogen Peroxide Guide Questions: 1. How do you come compare the volcanic eruptions using various substances? ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ 2.
