Question(s) Phenomena Scientific Practice(s) What We Figured Out Performance Expectation What happens to methanol and water as we heat them? Students observe that ice in a flask melts when heated and droplets start appearing under the watch glass over the flask. They observe that methanol melts in a flask and then solid menthol crystals appear under the watch glass over the flask. Conduct an Investigation Modeling Matter can change state of matter when heated or cooled. Matter must be moving as a gas from the bottom of the flask to the top. Develop a model to show how the air in the flask would look in a microscopic spot, as the ice and menthol are changes states. What when I try to pour water into a flask filled with air? Students observe that a flask filled with air, won’t let water fall into it through an open funnel on top. Conduct an Investigation Constructing Scientific Explanation Air has volume. Matter is anything that has mass & volume (takes up space) Construct a Scientific Explanation to Answer the question “Is Air Matter?” What things air can do? Students observe the teacher use a vacuum pump to remove air from a sealed flask. Students feel the end of the vacuum pump tubing and the gauge on the flask shows that air was sucked out of the flask. They observe the teacher pump air into the flask, which got harder to do with each pump and which led to the stopper popping Modeling Air can be removed from a container (less mass, same volume). Air can be added to a container (more mass, same volume). Develop a model to show how air can be added and removed from a container.
