2. Compare a model and mock up by the use of a Venn Diagram.
3. Five Reasons why we make use of models, mock ups, specimens and objects.
1. Overcome limitation of space and time. as a teacher you must present the model in your class discussion so that it can be easy to identify the learners for what the models presented in connection with your subject taught, this is also save time and space.
2. to "edit" reality for us to be able focus on parts or a process of a system that we intend to study. for example in using model and mock ups this would help a lot in focusing the parts of a process of a system that we intend to study, this will serve as a guide not to go beyond the topic.
3. To overcome difficulties. the reason why they neglect of doing an assignment or activity is the difficulty in looking for specimen with this they could overcome difficulties, they could compare this to other specimens objects.
4. To understand in accessible. With the models students have no reason to do what is being told to do such as activity that is hands on activity.
5. Help the learner understand abstractions. Students need not to imagine what is the topic you are talking about in science. at least with the use of models they could understand abstract ideas.
