Bio Build-up

Author(s): Nancy Moreno, PhD, and Barbara Tharp, MS.

Bio Build-up

This activity’s objectives are aligned with the National Science Education Standards, specifically those related to Science as Inquiry and Physical Science. In this activity, students will discover how pollutants can be disbursed throughout a food chain. Students will make a model of a simple food chain and observe how toxins can accumulate in consumers at the top of the chain. They will count, multiply, observe patterns, and draw conclusions.

Concepts

  • Pollutants often are absorbed by organisms near the base of a food chain. 
  • Toxic chemicals can become concentrated in the bodies of consumers, especially those near the top of the food chain.

Student Worksheets

Student pages in the teacher’s guide are provided in English and in Spanish.
