lab write up guidelines--
Remember to complete a bar graph for all 7 group- 3 bars per group!
LAB WRITE-UP Template
Use this template to assist you in typing your lab reports. Go back and delete this info so that your document looks like a lab report.
Format = 12 pt font in either Times new roman or Arial.
Name
Date
Period #
Title
Purpose: clearly states the reason for the experiment (identify the problem)
Hypothesis: states your prediction of the experiment using an “If, then” statement to reflect the dependent and independent variables. Also include your reasoning for the hypothesis.
Materials: a list of all the materials used in the experiment.
Procedure: An organized step by step plan written in numerical order so that another person could follow and duplicate your experiment. Be sure to identify the control and experimental group in your experimental design.
Results: Written results report only what happened in your experiment.
This includes all tables, charts, graphs, and drawings recorded during the lab.
NOTE: Format for graphs – a graph contains a proper title, labels (x-axis = independent variable and y-axis = the dependent variable), numbering that best fits data, and type of graph fits data (line, bar or pie graph).
Conclusion: Use complete sentences and include the following:
- State if your hypothesis is supported or refuted.
- State why the hypothesis is or is not supported.
- Use the data from your experiment to support your reasoning.
- Include background research to support your findings.
c. State what types of experimental error that you may have encountered.
d. State what improvements if any that you would make to this experiment.
e. State what you learned from this experiment.

Second set of window panes for honors biology: organelles, cells and cell transport. Due: Wednesday, September 11th
Test on Cells Friday, September 13th
1. Chloroplast- organelle found only in plant cells, it makes chemical energy (sugar/ glucose) using solar energy (sunlight) to combine water and carbon dioxide.
2. Mitochondrion (singular) - responsible for breaking down sugar (glucose from plants) into a more usable form (ATP) for our cells. Found in animal cells and plant cells. Cells that do more work have more mitochondria in their cells (muscle cells and sperm cells have the most!).
3. Centrioles- organelles found only in animal cells that are only active during cell division (mitosis) where their job is to make sure that duplicated DNA strands get pulled apart evenly.
4. Ribosomes- found in plant and animal cells, they are responsible for building proteins and enzymes in a cell by using instructions they receive from the DNA via an RNA strand.
5.Nucleus- the control center for the cell, it contains the DNA instructions used to make every part of your body, your DNA NEVER,NEVER, NEVER leaves the nucleus!!
6.Cell wall- found only in plants, it provides structure and support to plant cells.
7.Cell or plasma membrane- found in plant and animal cells, it controls the movement of all substances in and out of the cell. SUPER IMPORTANT!
8.Cytoplasm- gel-like substance that all of the organelles are suspended in, it provides a medium for nutrient exchange as well as a cushion for the organelles.
9. Active transport- transport of a substance across the cell membrane that requires energy!! When something moves from where there is less of a it t0 where there is more of it. This usually takes work. Imagine you are trying to push the last little bit of a sleeping bag into it's case.
10. diffusion or passive transport- transport of a substance across a cell membrane, this type does not require energy because the substance is usually small, like oxygen, and moving from where there is more of it to where there is less of it (with the concentration gradient). imagine a ball rolling drown a hill - from where it is highest to where it is lowest- no energy needed.
11. facilitated diffusion- this is a lot like passive transport in that it doesn't require energy. It does however require a door called a protein channel. this is because the substances are usually large, like a sugar molecule. These substances move with the concentration gradient (high to low) as well.
12. Osmosis (or diffusion of water)- is the movement of water (only water) across a cell membrane- this works with the concentration gradient as well, moving from where there is more water to where there is less. It does not require energy! ** note- water usually follows salt! If you've ever eaten too much salty popcorn at the movies you may have noticed that your hands get puffy. Your cells are soaking up fluids to balance out the salt in your cells. this is an example of how your body carries out homeostasis.
13. Fluid mosaic model- this refers to the way your cell membrane is made, it is made up of two floating layers composed of proteins and lipids. the membrane is constantly moving which allows substances to glide through it. the lipid layers insure that the water level in your cells is controlled- the inside lipid (fat)Layer holds the water in, the outside lipid (fat) layer keeps water out. the protein channels are like tunnels that take substances from one side of the cell all the way across both layers to the other side of the cell.
14. Eukaryotic cells- have membrane organelles, in particular a nucleus that holds its DNA. Animals, Plants, Fungi and Protists are made of these types of cells. They are thought to be a symbiotic relationship between cells that were once prokaryotic.
15.Prokaryotic cells- Don not have membrane bound organelles. They have DNA, but it is not kept inside of a nucleus, it is in the shape of a plasmid (circular) that floats around in the cell. ONLY BACTERIA are Prokaryotic
16. Euglena- a photosynthetic organism that lives in water. It has Chloroplasts and other organelles and is a unicellular (one celled) organisms made of cells like us- Eukaryotic! (It is a protist)
17. Paramecium- a one celled organism (protist) that swims (it also lives in water) using its cilia. It eats other organisms to survive.
18. Contractile vacuole- organelle in protists that helps them maintain proper water balance by helping to pump out excess water. They need this since they live in the water.
19. Plasmid- a circular strand of DNA found in bacteria.
20. Golgi body- organelle responsible for packaging substances made or excreted by your cells.

Summer Work UPDATE FOR MRS. FAULKNER and MRS. BRADLEY'S CLASSES
IF YOU HAVE MRS. FAULKNER, PLEASE EMAIL HER WITH ANY QUESTIONS REGARDING YOUR ASSIGNMENTS. sbfaulkner@gaston.k12.nc.us
If you are taking AP Biology or AP Environmental science we have made some adjustments to accommodate students who were unaware of the summer assignment given out at the end of last year.
The previous post contains the links to all of the summer work assigned.
For those of you taking either of these classes first semester:
Everything except for the reading assignment ("The Song of the Dodo" for AP Biology, or "Raising Elijah" for AP Environmental) will be due on Friday, August 30th, 2013.
The reading assignment for both classes will be due no later than Friday,September 27th, 2013.
For those of you taking either of these classes second semester:
ALL work will be due the first day of your class during second semester.
Already finished with everything?
All AP biology and AP environmental students, first and second semester:
If you have completed everything as originally assigned and hand it in the first day of school, August 26th, you will be rewarded for your efforts. You will receive 2 late passes- one for homework, one for labs or projects, you may use these during any grading period. ONE RULE: the work must be handed in a week ( 7 days) prior to the end of the grading period.

Assignments were given out the last week of school and were posted online (except for reading guides) before school let out last year.
If you are still needing the assignments for some reason you should go to my google site for the reading guides: https://sites.google.com/a/gaston.k12.nc.us/bradley-s-biology/ this is the same site as my tinyurl site:

APES EO Wilson study guide
Here's a link to the shared google doc, but as I told you in class Thursday, there is also a word document posted at my google site ; www.tinyurl.com/bradleybiology
google doc:
https://docs.google.com/document/d/1H_is9R9yyVYu3lSdMThYv_cIVODRzSkHFDXnYvIQpEE/edit?usp=sharing
If you have this done when you come to class your day will be infinitely easier!
