In class we discussed compressional waves in particular as to how they relate to sound. We also discussed the theoretical (and kind of gross) idea of the Brown Note.   Today we spent some time learning how to calculate the speed of a wave, which is the product of the frequency of the wave multiplied by its wavelength. You can check out a full tutorial to find any of these quantities here.
Today we made some waves of our own outside with different types of rope. On Monday we will analyze our data and continue our study of waves.
Much of today was spent discussing the parts of the two main types of waves we will study in this unit. Transverse Wave Compressional Wave
Continuing our investigation of heat transfer, today we discussed and demonstrated convection. In convection, warmer, less-dense materials moves up, allowing colder, more-dense materials to sink.  Mr. Powell is back from OWL and we are continuing our investigation of energy. This week we are exploring thermal (heat) energy, specifically about how this energy is transferred. In class today we did a quick experiment with conduction and saw that heat can be transferred through a metallic solid in through the process of conduction. |
