This activity is about habitat loss. Using hula hoops, traffic cones, rope and other materials, students will play a version of the game "tag" where they will simulate the impact of development on wildlife populations. The students will be able to recognize that habitat loss is a critical issue facing wildlife populations. This activity can be performed indoors or out; the suggested minimum size to ...

This activity is about the food web in the northern Bering sea. Working as a group, learners will create a list of the members of the food web and draw the web, using drawings or pictures, and showing the interconnectivity between its members. Using index cards and yarn, learners will then simulate the food web and reflect on the consequences of disruptions within it. Extensions to this activity are ... Full description.

Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates in an aquarium in their classroom. For an optional extension, teachers can take students to a local stream or pond to conduct field observations. Materials needed include sand, water, aquatics plants and insects; ... Full description.

This problem-based learning module focuses on the dilemma of wetlands management. The module is based upon the continued debate over the restoration of the natural cycle of water to the Florida Everglades. Students are challenged to perform an Earth system science analysis of the restoration of water level and flow to the Everglades ecosystem. They are also asked to predict the future survival of ...

Readings in this chapter guide student reflection on sustainability of the planet, and whether the Earth system is near a tipping point, where ecosystems will reorganize and seek a new equilibrium, with consequences for biodiversity. The resource includes a scientist profile, a video clip about Earth's tipping point (2012), and a personal reflection assignment. This is the sixth chapter in the unit, ... Full description.

This online, interactive "Chutes and Ladders" type of game is for ages 7-9 and can be played with a friend or against the computer. As players land on squares, depending on the described action, they either "leap" frog ahead if they help the environment or butterfly "flutter" back if they do not. The website includes a short explanation of why we should care about frogs and butterflies, as well as ... Full description.

In this activity, students learn how different classes of topographic features reflect light in characteristic ways, and how data captured by satellite sensors can be used to measure vegetation cover. They are introduced to the NDVI (Normalized Difference Vegetation Index) and use software to create a graph comparing the NDVI values in different parts of the map. The analysis results in a histogram, ... Full description.

In this simulation activity, students experiment with a population of M&M candies or paper dot "beetles" to test how well each color is adapted to survive on a field of colorful wrapping paper or fabric. Students act as predators and see that camouflaged beetles survive predation preferentially. Students reflect on how the activity could be modified to better simulate the process of predation-based ... Full description.

Students use a variety of utensil "beaks" to represent the feeding adaptations of different kinds of finches. Foraging on a lawn environment, students search for different kinds of food (yarn, beans and pasta) each having three color variants. Over the course of three trials, every student has a chance to forage and record data. In the last trial, some students can be given "mutations" which limit ... Full description.

Students learn about the connections between organisms in the ocean in this kinesthetic activity. Each student is given a card, identifying an organism, its food source, and its predators. Holding the end of a ball of yarn firmly, the ball is passed from organism to organism as they are linked in the predator-prey food web. Once all students are connected in the food web, an extinction event is simulated ... Full description.
