Yr 8 Science Students Explore Sound
Working through a number of different stations, Year 8 students experimented with how sound was made by using both everyday and specialised equipment. The objective was to learn what creates sound, and to learn about pitch and frequency and what affects the pitch and frequency of a sound.
The stations included water and dye in a glass, with students running their finger around the rim of the glass, three glasses the same size, but with different amounts of water in them, tuning forks on acoustic boxes using a mallet to strike the fork, the twanging of rubber bands of different thicknesses, the whirling of a balloon with a coin inside and then a small nut and larger nut inside, and twanging a popstick over the side of the table at different lengths.
Students had fun working their way around each of the stations, and then completing worksheets on the topic.
