Waves Unit Reflection



How does the use and study of waves affect societal well-being?
During this Unit we learned about Seismic Waves, Water Waves, Electromagnetic Waves, and Sound Waves. In the beginning of the unit I didn't really know anything about wave only about Microwaves but not as much as I know now. Also, I know about the waves that are in pools or at the beach. Without waves how would we be able to help humans from death and diseases without UV rays (new born babies in hospitals), x-rays or gamma rays (used in hospitals to treat cancer). Doctors use magnetic resonance and radio waves to see a picture of human’s tissue. Radio waves and the Doppler effect are used to find the speeds of moving vehicles and of moving balls at sport events such as tennis matches. 


What did I like?
I really liked how we started the whole unit. How we listened to songs, while that drawing waves, what we thought waves were. It was very good way to see how we would be embarrassed, because of our small knowledge about waves. 
What would you change or add for next year's grade 7 students? 
I think it would be more fun if there would be more group work
