Try this engaging digital review activity after teaching your students how to manipulate the wave formula (λ =c / ƒ where c= speed in m/s) to find the wave speed or velocity, wavelength or frequency. There are also a few problems that require the formula to find the period of a wave (ƒ = 1/T) where the period T is time in seconds.
To do this activity, you will share a Google Sheets link with your students that will allow them to Make A Copy of their own Magic Pixel Picture activity. They will calculate the answers for 17 different questions and type their answers into the numerical answer column. They will also need to choose the correct unit from the drop-down menu. If both the answer and unit are correct, color will magically appear in the cells on the right-hand side of the spreadsheet. If the answer and/or unit is incorrect, the color will not appear and the student will know that the answer and/or the unit is wrong. This Magic Pixel Picture is a cute frog!
This is a self-checking activity, so have students show you their finished picture to check that they are successfully manipulating the wave speed and frequency formulas! I have also included a link to the Answer Key for the activity, which you will also be able to add to your Drive.
Thanks for looking!
