Wave Tanks (HCPSIII 8.6.3 and NGSS PS 4-1, PS 4-2)
Thank you for letting us use the wave tanks again! The unit was split into two main activities. Part 1 was to use the wave tanks to explore different characteristics of waves (amplitude, frequency, and wavelength). They then used the speed equations (distance/time and frequency*wavelength) to calculate speed. Part 2 was to use the engineering design process to create a boat to then race across the length of the wave tank. Students could choose from either wind energy (blown air through a straw) or paddle energy (using the paddle). The constraints: small enough to fit into the tank and no electrical components.

Aloha @lifescienceswahiawa,

Thank you so much for sharing! These kinds of tactile learning experiences and application of the engineering design process are so powerful. We are very fortunate to be able to support teachers like you. Mahalo for all that you do!
