Science Conceptual Frameworik

What were some new learnings, something that you may have already known, or some questions you still have?  I was interested in the idea that waves pass through each other.  Although this makes complete sense from observations like ripples in the water and echoes and being able to hear different sounds ta the same time, I really hadn’t thought about it before.

What preconceptions do you anticipate your students will have about topics found in this standard?  All waves must have a medium that they are traveling through.  Waves collide and are destroyed.  Waves lose energy.  Waves can’t travel through everything.

What are some ways you plan on addressing these preconceptions? I would have the students experiment using sound and transferring the waves through different medium. We would also look at light as it travels through space, air, clouds, etc.  Tying in with previous learnings about sound transmission, we will take a deeper look at the “phones’ that we made.
