Matter and Energy Lab Report Introduction For this lab activity, you will observe two scenarios — The Iced Tea Debate and Salty Soup — and record your observations of physical and chemical change. During your observations, you will determine how each scenario represents the laws of conservation of matter and energy. Problem: How can matter and energy be described and conserved in a variety of systems? Hypotheses: As you view each scenario, make a prediction about what will occur when prompted by the video. The Iced Tea Debate The Salty Soup Predictions—What do you think will happen? Materials: 1. Demonstrations: “The Iced Tea Debate” and “The Salty Soup.” Procedures: 1. Observe and analyze the following video demonstrations: “The Iced Tea Debate” and “The Salty Soup.” 2. Use the data table to record observations on physical and chemical change, and the conservation of matter and energy. Variables: List the variables for The Iced Tea Debate: Independent: Dependent: Control: List the variables for The Salty Soup: Independent: Dependent: Control: Data and Observations: Record your detailed observations and draw some brief conclusions in the table below. The Iced Tea Debate The Salty Soup Describe the physical changes you observed. Describe the chemical changes you observed. Describe the instances of conservation of matter and energy in each demonstration. Questions and Conclusion 1. How was matter and energy conserved in each demonstration? 2. What phase changes did you observe? 3. What kind/s of energy transfers did you notice in each scenario? 4. Identify an example of matter and energy conservation in the world around you. Conclusion: How did your observations support or contradict your predictions? Describe an experiment that could further explore physical or chemical change.
