BayQuest — A Journey of Exploration
Introduction and Standards
In this interactive, students have to locate five plants and/or animals that live in or around the Bay. Once they locate all five, students use their PDAs to report back to the PROduction Company: what is the connection between these organisms and their habitat? Should their stories be included in the television series?
3.0 Life Science
- Explain that individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and reproducing.
a. Describe ways in which organisms in one habitat differ from those in another habitat and consider how these differences help them survive and reproduce.
b. Explain that the characteristics of an organism affect its ability to survive and reproduce.
- Explain that in any particular environment, the growth and survival of organisms and species depend on the physical conditions.
b. Explain that in all environments-freshwater, marine, forest, desert, grassland, mountain, and others-organisms with similar needs may compete with one another for resources, including food, space, water, air, and shelter.
c. Explain that in any particular environment individual organisms with certain traits are more likely than others to survive and have offspring.
- Explain ways that individuals and groups of organisms interact with each other and their environment.
a. Identify and describe the interactions of organisms present in a habitat.
- Competition for space, food, and water
- Beneficial interactions: nesting, pollination, seed dispersal
- Roles within food chains and webs: scavengers, decomposers, etc.
- Give reasons supporting the fact that the number of organisms an environment can support depends on the physical conditions and resources available.
c. Explain that within any environment organisms with similar needs may compete with one another for resources.
d. Cite examples to illustrate that competition is reduced when organisms use different sets of resources, such as birds in a forest eat different kinds and sizes of seeds.
