Math Skill: Number comparison and expanded notation

Science Subject: Protection of Earth’s resources

Grade level: 3rd grade

Environmental Area: Reduce Reuse Recycle

Purpose: Understand trends in the amount of recyclable materials collected in Vanderburgh County through the curbside program and develop awareness of waste reduction

BACKGROUND FOR THE TEACHER

The city of Evansville provides several recycling services, including a curbside recycling program, electronics recycling, tire recycling, yard-waste recycling, and drop-off recycling. Among them, the amount of recyclable materials collected through the curbside recycling program makes up a dominant portion (see the table below). Residents in the city of Evansville are provided a 96-gallon bin to place recyclable materials. Over 60,000 bines were distributed as of June 2020. The amount of recyclables collected through the services significantly increased in 2013, however it has not improved much since then (See the figure below). The residential recycling rate was about 13% in 2019.

In 2014, House Enrolled Act 1183 (HEA 1183) established a 50 percent recycling goal for Indiana. Educating the importance of recycling in Evansville becomes more critical than ever.
