Introducing Phase and Phase Change Investigation Question: How does the appearance of a substance change when it changes phase? Answering this question will be our first step toward figuring out if the methane lake on Titan froze or evaporated. We cannot directly study phase changes on Titan. Instead, we will study phase changes on Earth to help us understand what is happening on Titan.

Discussing Difference in Appearance Phase Change Video Discussion Discuss the phase change videos with your partner. Pick one of the videos and answer the following questions about it below. Include words from the word bank in your responses. Word Bank condensation does not flow evaporation flows freezing gas has its own shape invisible liquid melting phase change solid takes the shape of its container visible 1. How would you describe the appearance of the substance before the phase change? 2. How would you describe the appearance of the substance after the phase change? 3. Based on your description, choose which phase change you think occurred in your video.
