***Particle Model of Matter and Intermolecular Interactions***
Is it ever possible to teach students intermolecular interactions without knowing about the particle model of matter?
Do students really know what is meant by a scientific theory? Do they realize that the whole concept of 'intermolecular interactions' is a theory put forward to explain the unusual behaviors of substances as the temperature is raised?
This is what is unit is designed to explore.
Each lesson is designed to have three parts - an appetizer, main course, and desert (I have a sense of humor :).
The lesson plans for each lesson provide the teacher with instructions, and notes on the content covered in class. Each lesson has a presentation, which is included as PowerPoint slides or as Smartnotebook pages.
In either case, there is a 30-page workbook that students are expected to use during this unit. No additional paper is required. no cutting and pasting into an interactive notebook so no mess. This workbook interacts with the lesson, and the teacher.
The lessons follow a progression:
Lesson 1 - introduces the particle theory through a brief historic perspective.
Lesson 2 - students are presented with three sets of data on melting points and boiling points of substances and groups of substances. They analyze this data through representing them graphically and describing trends, identifying anomalies. From this lesson they will begin to see that intermolecular forces has a role in the physical properties of matter.
Lesson 3 - Students are introduced to the three types of intermolecular interactions - dispersion forces, dipole-dipole interactions, and hydrogen bonding. With the knowledge of these forces, they now go back to data from Lesson 2 to explain using the correct terminology.
Lesson 4 - is a lab. Here students observe properties of liquids - viscosity, surface tension, and capillary action. They then attempt to explain these properties through illustrations using the particle theory of matter, and relating the behaviors to intermolecular interactions.
This is a 30 page document students use for the entire teaching of this unit. I call this the LESSON-INTERACTIVE WORKBOOK. Because I designed it this way.The workbook is allows for students to interact with the slide presentations.
the idea came about as I watch my students drift into a daydream during a slide presentation. So now students interact with the lesson through directed activities in the workbook.
All classwork and homework is part of the workbook, as is the lab report for Lesson 4.
The pages can be printed out and stapled together to make a booklet, or placed into a binder.
