In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

In this activity, learners work in small groups to match various marine animals with their different environments.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this math activity, learners use a "function machine" to collect and organize simple data. The function machine in this case is a cardboard box and the input/output data are paper fish.

In this game, students will become familiar with fish shapes, learn that fish within a given taxonomic family have similar body shapes, and discuss how different body shapes enable fish to survive in

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this hands-on activity, learners discover the similarities and differences between a vertebrate and invertebrate by dissecting a perch and a crawfish.

In this hands-on art activity, learners will study and identify features of the external anatomy of a fish.
