01.06 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.
