Atomic Theory and Model Lesson – The History of the Atom:
This 18 slide Atomic Model lesson package examines the history of the atomic theory including the contributions of key persons as well as their influence on how the atom was perceived in their time including Democritus, Dalton (Ball Model), J.J. Thompson (Raisin Bun Model), Rutherford (Gold Foil Experiment) and Bohr (Energy Level Model). The lesson package also includes an inquiry activity to be done prior to the lesson which gets the students really thinking about how the atom was developed.
There are 3 videos embedded in the PowerPoint. Simply start the slideshow and click the image and it will open in your browser. The PowerPoint contains diagrams, examples and explanations. It includes the lesson (student and teacher versions of the PowerPoint) and a student lesson handout as a word document which follows the PowerPoint.

– Student lesson handout
In order, the lesson covers:
– Atomic Theory Matching
– Atom Size

– J.J. Thompson – Raisin Bun Model
– Rutherford – Gold Foil Experiment
– Bohr – Energy Level Model
The student version of the power point contains multiple blanks that need to be filled in throughout the lesson. These blanks are conveniently underlined and bolded on the teacher copy. I have found this to be the most effective means of keeping my students engaged and active without having them write everything out. This also leaves more time for discussion and activities.
I also have a range assignments and lessons/units from other grade levels at my store. Please come, have a look around and don’t forget to follow if you like what you see.
