text: There many things in the new technology that would be valuable in a classroom with students. For instance, it help tell how students are feeling. Also it could tell if a student is faking a smile and is really upset. Finally, it would be a helpful learning tool by changing lessons by the students emotions. Next time you see a facial expression try telling what emotion that it applies to.Cars are the most common use of transportation is todays society, but can limiting car usage be beniftial to our citizens? While you read this i want you to think how this can benefit you. Have you ever considered walking over driving, maybe even biking over driving, if not i want you to consider it next time you go to the gym or wherever you go. Limiting our car usage can be done in many types pf ways, such as: walking, biking, or jogging. If we walk instead ov drive not only are we getting to where we need to be, but you also get a workout. Same as jogging and biking, as you can see limiting car usage isnt that bad becasue you can do your body a much needed favor and get some exercise. We all know how we complain about gas prices, so if you cut back on driving you wont have to worry about gas. These are just two of many ways we can limit our car usage.          Dear principal,
