In today’s science class, students created the model that demonstrate what could restrict the size of fish populations in the pound. In this activity they have used construction paper as a pound and building block as a fish. They have learned that population cannot increase indefinitely. Availability of food and shelter, clean water, diseases, space and buildup of waste products limit growth.
