Grade 7 – Physics - Making musical instrument.





Students made wind instrument with help of straw, chart paper & glue. They stuck the straw & had cut the paper in slant to get different length of straws.
When air was blown through it, a musical sound was produced which proved that with the increase in length of vibrating string, frequency decreases & vice-versa.
They enjoyed the activity.
