Students' Projects - Grade 6

During my School Internship, I was handling grades 6 and 9. In the grade 6 textbook, there is a lesson titled 'Trip to Ooty' which is an anecdote of a group of school students going on a school excursion in the Ooty Toy Train.  After I finished teaching the lesson, I had asked the students to make models of the Toy Train using whatever resources they had. Many students had contributed to it out of which two were outstanding. One was a boy who made a large model of the train using many different carton boxes, while the other one was that of a boy who made a smaller one, but more of a working model. In fact, his model operated on the principle of repulsion between two magnets which was quite commendable at that age to achieve.
