Atomic Models - Questions

The Atomic Models Concept Builder is comprised of four different Matching Pairs activities.  In order to complete any of the activities, learners must successfully associate four pairs of ideas. In the first activity - Scientists and Models - learners associate the name of a scientist with the name of the atomic model that they developed. In the second activity - Discoveries and Models - learners associate a specific discovery or experiment with a description of a model that the finding led to. In the third activity - Electrons and Models - learners associate the name of a model with a description of what the model uniquely proposes about the electron. And in the fourth activity - Diagrams and Models - learners associate a pictoral representation of a model with the name of the model. The Concept Builder scrambles the arrangement of ideas within the Matching Pairs grid. Otherwise, all students will have the same set of terms.

Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes.

Atomic Models

This activity presents learners with 8 different statements that must be matched by meaning. Learners tap on the statements to select them and then tap on the Check Match button. The order of the statements is randomized. A mis-matched pair restarts the game and re-randomizes the order of the statements. The statements are ...
