THIS WEEK:

• We began section 3 on DNA and genetics
• Finished section 2 on reproduction; you should be an expert on reproduction in plants and animals! Okay, maybe not an expert...but close!

HOMEWORK:

• You should already have handed in your final copy of "Our Ecosystem" assignment/lab
• Read page 38-54 in your textbook

• our class identified common plant and animal species in the ecosystem
• We recognized examples of interdependence and symbiosis in our ecosystem
• Reproduction was learned about by looking at real organisms
