4th Grade Explores Sound Waves and Communication

Ms. Abby Thomas and Mrs. Sheree's 4th grade classes have begun their final unit focusing on Sound Waves and Communication. To introduce the unit, students participated in hands-on investigations to better understand how waves are created and how energy moves.

Using ropes and slinkies, students explored two types of wave motion:

• Transverse waves - created by moving the rope up and down

• Longitudinal waves - created by pushing and pulling the slinky side to side

Through these activities, students observed how motiuon energy travels through a medium. Most importantly, they discovered that they were the source of the energy creating the waves. By applying force with their hands, they were able to generate visible wave patterns and observe energy transfer in real time.

This engaging lesson allowed students to connect physical movement to scientific concepts, laying a strong foundation for understanding sound waves and communication.

We are proud of our 4th graders for their curiosity, teamwork, and enthusiasm as they dive into this exciting unit!
