Inheritance of Traits

Traits are physical characteristics that:

Have as many family members as possible complete this survey of traits and discuss the similarities and differences.  You can use Google to look up each characteristic (detached earlobes, dimples, etc).

Follow along with this informative video to learn about Punnet Squares and how traits get passed on.  

Selective Breeding

Have lots of fun learning about Selective Breeding (the ways that humans can influence the traits in other living things).  Click this link to follow the simulation.  Take notes of what you learn.

Abiotic and Biotic Factors 

Biotic factors are the living things in the environment.  

Abiotic factors are the non-living things or features of the environment.  

Neither biotic or abiotic factors are more important.  The biotic factors depend on the abiotic factors in many ways.

Take a nature walk through a trail, your neighborhood, or your backyard, and record a list of 8 biotic and 8 abiotic things you see.  Remember to look carefully:

Features of Large Ecosystems

There are many large ecosystems on Earth.  Some are large terrestrial (land) ecosystems called Biomes.  Others are large aquatic (water) ecosystems. 

Whether terrestrial or aquatic, large ecosystems have common features that distinguish them: location, availability of resources, availability of food, and types of organisms.  Some additional features of terrestrial biomes include climate and precipitation.


WEB QUEST:  Use the internet to learn about the common features of some terrestrial biomes.  

Click here and complete the chart by searching and reading about each of the terrestrial biomes listed.  


TRIVIA:  Which terrestrial biome most closely matches our environment in Georgia?  

Use what you learned in the web quest to form a clear and comprehensive explanation of why you chose your answer.
