1The Music-and-Bean-Plant Science Fair Project
Okafor's ninth-grade science fair season is underway, and Priya submits a project titled 'Classical Music Makes Plants Grow Faster.' Priya placed six bean seedlings on the classroom windowsill beside a speaker that played a classical radio station at roughly 70 dB for eight hours a day. Six more seedlings went into a dark storage closet, where the radio could not be heard.

Students in an environmental science class are monitoring a 40-hectare lake that receives runoff from a golf course and from aging septic systems. From May to September they record: total phosphorus rising from 12 to 48 µg/L; chlorophyll a rising from 4 to 28 µg/L; Secchi depth falling from 2.4 m to 0.6 m; dissolved oxygen at 8 m falling from 8 mg/L to 2 mg/L; nitrate staying between 0.05 and 0.08 mg/L all summer.

A teacher finds a press release that reads: 'Students who use the StudyBoost app score 27% higher on tests.' The release describes a study in which 38 high school students who had downloaded StudyBoost on their own were compared with 38 classmates who had not. All 76 took a 10-question quiz at home, on their own devices, and reported their scores through a web form; the app users averaged 7.0 correct and the non-users averaged 5.5 correct, a 27% difference.
