Pennsylvania Science Standards

   Biological Sciences Grade 4

A. Know the similarities and differences of
living things.

· Identify life processes of living things (e.g., growth, digestion, react to environment).

NatureWorks Episodes

1. Adaptation
2. Coloration
3. Natural Communication
4. Migration
9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers
12. Population Dynamics
14. Niche

· Know that some organisms have similar external characteristics (e.g., anatomical characteristics; appendages, type of covering, body segments) and that similarities and differences are related to
environmental circumstances.

B. Know that living things are made up of
parts that have specific functions.

· Identify examples of unicellular and
multicellular organisms.

· Determine how different parts of a living thing work together to make the organism function.

C. Know that characteristics are inherited
and thus offspring closely resemble their parents.

· Identify characteristics for animal and plant survival in different climates.
