Population Dynamics

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

All mammals have warm blood, are vertebrates, breathe with their lungs, have hair or fur on their bodies, and produce milk for their young. But not all mammals give birth to their young in the same manner. Watch a video that explains how...

Explore growth patterns in wildlife populations.

Learners determine the type of data needed to test their inferences. As homework, they check and record heart rates of fellow students, teachers and family members. During their next class period, learners enter all data into the database.

Students play a game about the life cycle of a blue crab in order to witness the causes of changes in the crab population and discuss what a resource manager could do to keep a stable crab population. Students then create a game titled...

In this organisms and their environment activity, students will review concepts relating to ecological studies, levels of organization in ecology, and relationships between organisms in ecosystems. This activity has 10 fill in the blank,...

Students use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.

Students develop the concepts of flood stage, levees, floodplain, and the dynamics of river flooding. They construct river models and test various flow rates and volumes. This lesson has an excellent experiment for students to do.

Students assess the factors affecting animal populations. Working in groups they define specific vocabulary terms and complete several activities from "Project Wild."
