This web quest will walk you through some of the scientists, discoveries, experiments and models that helped to shape early atomic theory. You will need the Web Quest worksheet, the "History of Atomic Structure" article and a device with internet access to complete the exercise.
Each step of the quest is listed below starting with Democritus and working through Niels Bohr. Please move through the activity in the order below so that you can see how the model was built from the time of the ancient Greeks through the mid 20th century. By the end of the activity, you should have a good understanding of how the model of the atom has evolved and the scientific discoveries that led to this evolution. Have fun!
