For example, student voices may echo off the walls or students may have to talk loudly because they sit far apart. To help with this problem, you can develop an invention that would stop the sound from echoing and allow students to talk quieter in the cafeteria. By covering the walls with something soft, the sound in the cafeteria won't echo.
If you lift up a student's backpack, you would notice how heavy it is from the books and materials he or she must carry. It is difficult for young students to carry around these heavy backpacks.

Your solution may be a way to transport the backpack without carrying all the weight or to make the backpack lighter.
A Friendly Reminder
