Experiment 3: Thermal Expansion What is thermal expansion and how why does it lead to sea level rise? Procedure: Make an by filling a beaker with water and adding a pinch of salt and “ocean” food coloring. In the place a few ice cubes in the blue water to represent “ocean,” icebergs/polar ice caps. Mark the water level (“sea level”) with tape. Do you that the level” will decrease or increase when it is heated? “sea Heat the water in the microwave for 2 mins and take another level” “sea measurement. (NOTE: exercise great caution when handling the beaker after heating!) After Lab Questions: From Experiment 1, after adding the Bromothymol blue to create your “ocean,” did the color turn blue or yellow? A) From Experiment 1, after adding the dry ice (cooled and compressed CO2) to the did the color change? “ocean,” B) If yes, what does this indicate?
