Curriculum, Manual


Setting up a valid experiment can be the toughest part of the scientific method for young scientists. A poorly designed experiment can make data hard to understand and even meaningless. The purpose of this tutorial is to teach basic fundamentals of experiment design and data collection/interpretation.

Reviewer Comments:

Inspired by a ‘significant trash problem’ this 3-class period lesson was funded by the Sea Grant Program at the University of Guam, however its goals are applicable to most regions of the world. The lessons are engaging and varied and are adaptable for grades 3 – 12. This part (1 of 2) requires only easily accessible materials (trash & Internet). Assessment ideas are included (a “Good Litter Survey” functions as a pre- and post-test), and lessons focus on types of trash (biodegradable vs. non-biodegradable), decomposition rates, the North Pacific Gyre, and personal trash assessment. There is also a link to part 2 entitled “Where the Waste Goes – The Dump.”
