Dec 19th Class Assignment
Getting the Lab(right) Write
You have 10 minutes to create a few summary sentences for each section of the lab report. This is to go into your lab book to use as a reference to help you create a fluid lab report. In the last lab many of the reports showed that there was a disconnect between sections.
After creating the summary outline as an individual you are to take your specific section and create a specific outline for it. Use labwrite to help you with this. (20 minutes)
Organize yourselves by lab group job(i.e. This is the first improvement that can be made. princ invest, data, safety, comm.) and exchange outlines. Add to your outline based on the discussions you have within your group. Underline any additions to your outline (8-10min)
Homework
Write the rough draft of your lab section for peer review tomorrow in class. You must have both a hard copy (for review) and an electronic copy. (for correcting and sharing with your lab group)
Lab Job
Lab Report Responsibilities
Principle investigator- Abs, Method, Biblio, Title, Format
Communicator-Introduction
Material manager/ Safety-Discussion
Data Collector-Results
Things to remember when writing
1. When describing a concept go from general to specific. Then give a real world example for the concept. One that illustrates to the reader how this may affect the world around them.
2. Say what you mean, mean what you say.
3. Use the appropriate terminology. The terms you have learned are an integral part of how biologist communicate. Make sure you are using them when possible.

Biome Project
Biome Storybook Project
Directions:
You and a partner are to create a children’s storybook about the biomes of the Earth.
The goal of this storybook is to teach the reader about the global factors as well as the local factors that influence a biome.
Minimum Requirements
o The storybook can be either hand drawn or produced on PowerPoint. (a combination of both is also fine)
o Must have a logical and well thought storyline with developed characters and plot.
o Your characters must visit a minimum of 10 separate biomes. (terrestrial and aquatic)
o There must be a minimum of 3 abiotic and 3 biotic factors shown in the graphic or discussed per biome.(local)
o You must explain why these factors exist from a global perspective. I.e. rain shadow effect in the Andes as a result of the direction of airflow in that section of the world.
o Must have a front cover with graphic, title and names of authors.
o Must have a back cover with a short Authors biography.
