Title: Mentos, Soda, and Nucleation
In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students will then work in groups to determine what their hypothesis is about what is happening and why. The students will be given a chance to debate with other students about why their hypothesis is correct. This lesson could be used in eighth grade physical science, physical science, chemistry, and/or physics.
Standard(s): [S1] (8) 1: Identify steps within the scientific process.
Title: What's the Matter - Concentration Game
What’s the Matter? is a guided inquiry lesson on classification of matter, physical and chemical properties, and physical and chemical changes. There are two parts to this lesson: (a) concentration game for definitions and (b) concentration game for matter classification, physical and chemical properties, and physical and chemical changes. This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
Standard(s): [S1] PHS (9-12) 5: Describe physical and chemical changes in terms of endothermic and exothermic processes.
Title: Which Came First, Ice Cream or Refrigeration?
As students begin their study of states of matter, this hands-on activity demonstrates how the interaction of a solid and a liquid can reverse the initial state of each material.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
Standard(s): [S1] CHE (9-12) 5: Use the kinetic theory to explain states of matter, phase changes, solubility, and chemical reactions.
Title: Cold Car Start
In this Science Update, from Science NetLinks, you'll hear how wind chill affects car engines. Wind makes the temperature feel colder because it carries heat away from our bodies; it affects car engines in a similar way. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.
Standard(s): [S1] CHE (9-12) 8: Distinguish among endothermic and exothermic physical and chemical changes.
Title: Analyze the Data
In this lesson, one of a multi-part unit from Illuminations, students explore rates of change and accumulation in context. They calculate concentrations and flow rates and use an interactive Java applet to graph their data.
Standard(s): [MA2015] AL1 (9-12) 46: Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. [S-ID7]
