(S7MT-Ia-1) Direction: Use the scientific method in solving the problem below through an experiment. Take a picture or a video while performing the experiment. Observation Ask a Question Form a Hypothesis Design an Experiment List down the materials Create a procedure or list down steps to follow in the experiment Draw the setups Identify the variables The Scientific Method One summer day, you dump ice cubes into your glass of soft drink. Accidentally one ice cube fell into your glass table and you observed that it is slowly melting. You wondered how you could make them melt more slowly or faster. What melts ice the fastest? Hypothesis: Materials: 4 ice cubes (same size and shape) 4 drinking glasses (same size and shape) Teaspoon ½ tsp table salt ½ tsp sugar ½ tsp sand Watch /clock/timer Procedure: 1. Prepare all the materials. 2. 3. 4. 5. Note: Add more numbers if necessary. Draw and label the set-up. Glass A drinking glass, ice Glass B drinking glass, ice + table salt Glass C drinking glass, ice + sugar Glass D drinking glass, ice+ sand Identify the variables: 1. Controlled variable: 2. Independent variable: 3. Dependent Variable: Record and Analyze Results Make a Conclusion Time it took to melt (mins) Glass A Glass B Glass C Glass D
