Composition of the Atom

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their results to Rutherford's experiment. Students discuss the subatomic particles of the atom and using a handout of the periodic table they construct a model of a magnesium atom using toothpicks and gumdrops.

It is so helpful to have so many resources on one website. Sources that used to take hours of hunting on line now take little time to locate. In the event of a change of plans or if I need sub plans for the day, my work is done.
