Title: Dryer Sheets
In this Science Update, from Science NetLinks, you'll hear how the old saying opposites attract relates to your laundry. Positively charged particles are attracted to negatively charged particles, which can cause static cling in clothing. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.
Standard(s): [S1] PHY (9-12) 8: Summarize similarities in the calculation of electrical, magnetic, and gravitational forces between objects.

[SC2015] PHYS (9-12) 9: Obtain and evaluate information regarding technical devices to describe wave propagation of electromagnetic radiation and compare it to sound propagation. (e.g., wireless telephones, magnetic resonance imaging [MRI], microwave systems, Radio Detection and Ranging [RADAR], SONAR, ultrasound).Digital Tool Description: In this lesson students will calculate terms of a geometric sequence to determine frequencies of the chromatic scale using a graphic calculator. Students will then compare sine waves to see and hear the trigonometry behind harmonious and dissonant note combinations.
