This activity would provide a good excuse for getting out the sensor kit and carrying out an experiment on how well different materials muffle sound.
Use it to reinforce the discussion on fair testing and the handling of data. Print the table and plot a graph. Ask what type of graph could be used. Retest the materials and extend the table to include other materials.
Talk about pitch and why you get different results for different pitches. Is the trend the same for all materials.
