We have kicked off PLTW STEAM Learning at Bryant! First Grade has been studying light and sound and doing many investigations to help understand important ideas around these topics. We have explored how vibrations create sound by experimenting with tuning forks, rubber bands and cups, and metal water bottles to name a few items. Students have also explored how light behaves when it shines on different materials such as mirrors, and translucent, transparent, and opaque objects. First graders will work in partners and use this knowledge of light and sound that they have acquired to build a device that will communicate over a long distance.
First Graders also were inspired by the words of Dr. James E. West, co-creator of components of the modern microphone, and we took a look inside our flashlights and tried to figure out how they worked!
