Using everyday materials, third graders will be designing and creating a technology that can change in both pitch and volume. We agreed that the pitch should change so that it can be heard over the different levels of pitch in the cafeteria (meaning the voices of Kindergartners have a different pitch than our fifth graders)! And it should absolutely change in volume in case the volume of the cafeteria changes, too.
Our first focus as engineers is always asking good questions, and third graders have reviewed how we can change both the pitch and the volume of various technologies. Third graders have moved on to brainstorming their technology designs and will then plan out their designs with a partner! Check back soon to see how some of their plans come into action! Will they be able to change both in pitch and in volume? Will they also be able to get everyone's attention in the noisy cafeteria?
