IBO MISSION STATEMENT
The International Baccalaureate Organization aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect. To this end the IBO works with schools, governments and international organizations to develop challenging programmes of international education and rigorous assessment. These programmes encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right.
3
As IB learners we strive to be: INQUIRERS We nurture our curiosity, developing skills for inquiry and research. We know how to learn independently and with others. We learn with enthusiasm and sustain our love of learning throughout life.
OPEN-‐MINDED We critically appreciate our own cultures and personal histories, as well as the values and traditions of others. We seek and evaluate a range of points of view, and we are willing to grow from the experience.
KNOWLEDGEABLE We develop and use conceptual understanding, exploring knowledge across a range of disciplines. We engage with issues and ideas that have local and global significance.
CARING We show empathy, compassion and respect. We have a commitment to service, and we act to make positive difference in the lives of others and in the world around us.
THINKERS We use critical thinking skills to analyse and take responsible action on complex problems. We exercise initiative in making reasoned, ethical decisions.
RISK-‐TAKERS We approach uncertainty with forethought and determination; we work independently and cooperatively to explore new ideas and innovative strategies. We are resourceful and resilient in the face of challenges.
COMMUNICATORS We express ourselves confidently and creatively in more than one language and in many ways. We collaborate effectively, listening carefully to the perspectives of other individuals and groups.
BALANCED We understand the importance of balancing different aspects of our lives – intellectual, physical, and emotional – to achieve well-‐being for ourselves and others. We recognize our interdependence with other people and with the world in which we live.
PRINCIPLED We act with integrity and honesty, with a strong sense of fairness and justice, and with respect for the dignity and rights of people everywhere. We take responsibility for our actions and their consequences.
REFLECTIVE We thoughtfully consider the world and our own ideas and experience. We work to understand our strengths and weaknesses in order to support our learning and personal development.

The Grade: FHS: Students will receive a grade for their Flathead High School transcript based on the following scale. Assessments – 50% Lab Work – 30% Homework – 20% Semester Exam – 20% IB: Students will receive a cumulative score from the International Baccalaureate Organization at the end of this two-‐year course of study. This score will be derived using the following scale. Internal Assessment (IA) – 20% External Assessment (EA) – 80% One scientific investigation – internally assessed by the teacher and externally moderated by IB. The performance is marked against common criteria, with a total mark out of 24.
Paper 1 – 20%: 40 multiple choice questions Paper 2 – 36%: DBQs, short answer and extended response questions Paper 3 – 24%: short answer and extended response questions
To be practiced throughout the 18-‐month enrollment in this course concluding with a final, independent, IA during the second year of the course.
To be assessed May 2016 over two days.
Finding Success:
External Assessment (EA): Every summative assessment taken for an FHS grade will be composed of previous IB EA exam questions. Students will have the opportunity to practice exam questions in individual topics prior to the May 2016 exams. Success in the EA is dependent on knowledge of content and the ability to interpret exam questions. The following terms will begin almost every exam question. Familiarity with their meaning will help in the appropriate answering of exam questions.

Internal Assessment (IA): This requirement enables students to demonstrate the application of their skills and knowledge and to pursue their personal interests, without the time limitations and other constraints that are associated with written exams. Students will practice the art of internal assessment throughout the 18-‐month course with a final IA that will be submitted for moderation during the senior year. The following documents are all essential for successful completion of the student’s IA. Academic Honesty – Academic honesty in the Diploma Programme is a set of values and behaviors informed by the attributes of the learner profile. In teaching, learning and assessment, academic honesty serves to promote personal integrity, engender respect for the integrity of others and their work, and ensure that all students have an equal opportunity to demonstrate the knowledge and skills they acquire during their studies. All coursework – including work submitted for assessment – is to be authentic based on the student’s individual and original ideas with the ideas and work of others fully acknowledged. Assessment tasks that require teachers to provide guidance to students or that require students to work collaboratively must be completed in full compliance with the detailed guidelines provided by the IB for the relevant subjects. For further information on academic honesty in the IB and the Diploma Programme, please consult the IB publications Academic honesty, The Diploma Programme: From principles into practice and General regulations: Diploma Programme. Specific information regarding academic honesty as it pertains to external and internal assessment components of this Diploma Programme subject can be found in this guide.

21 Sep. 2012. Lab Possibilities – The internal assessment task will be one scientific investigation taking about 10 hours and the write-‐up should be about 6 to 12 pages long. Investigations exceeding this length will be penalized in the communication criterion as lacking in conciseness. The task produced should be complex and commensurate with the level of the course. It should require a purposeful research question and the scientific rationale for it. Investigations my include: hands-‐on laboratory investigation, extracting data from a database and analyzing it graphically, or using a simulation provided it is interactive and open-‐ended.
8
IB Animal Experimentation Policy – This policy applies to all experimentation in IB World Schools, whether assessed or non-‐ assessed, for extended essays or for the group 4 project, in classrooms or school laboratories, or in other locations where IB students may conduct experiments. The IB policy may be more stringent than some local or national standards for experimentation in schools. Bearing in mind its mission statement, the IB should be in the vanguard of ethical behavior. The policy is based upon the established 3Rs principle (replacement, refinement and reduction), in which any experimentation involving animals should initially consider: replacement of the animals by using cells, plants or computer simulations; refinement to the experiment to alleviate any harm or distress to the animal; and reduction in the numbers of animals involved. Our standards for work in schools should also be more stringent than those of university and R&D research committees as we are not carrying out essential, groundbreaking research. Practical work in schools has other purposes such as reinforcing concepts and teaching practical skills and techniques. Even in a practically based extended essay the work will not be fundamental research. • Any planned and actual experimentation involving animals must be subject to approval following a discussion between teacher and student(s) based on the IB animal experimentation policy. • Experiments involving animals must be based on observing and measuring aspects of natural animal behavior. Any experimentation should not result in any pain or undue stress on any animal (vertebrate or invertebrate) or compromise its health in any way. Therefore experiments that administer drugs or medicines or manipulate the environment or diet beyond that which is easily tolerated by the animal are unacceptable. Experiments resulting in the death of any animal are unacceptable. • Any experimentation involving humans must be with their written permission and must follow the above guidelines. Experiments involving body fluids must not be performed due to the risk of the transmission of blood-‐borne pathogens. Internal assessment moderators or extended essay examiners who see evidence of breaches of the above policy in the sample work sent for moderation or in extended essays are required to complete a problem report form (PRF) to be submitted to IB Cardiff. The internal assessment section of the group 4 subject reports for May and November examination sessions will contain examples of experiments deemed to be unacceptable. Animal dissection There is no requirement in the group 4 experimental sciences for students to witness or carry out a dissection of any animal, vertebrate or invertebrate. If teachers believe that it is an important educational experience and wish to include dissections in the 4/PSOW they must apply the following policy. • Discuss reasons for dissections of whole animals with the students. • Allow any student who wishes to opt out of the dissection to do so. • Seek to reduce the number of dissections.
• Seek to replace animal dissection with computer simulations and/or use animal tissue, for example, hearts and lungs obtained from butchers.
• Dissect animals obtained from an ethical source only, for example, no wild animals or animals killed on the road.
9
Assessment Criteria – Students will be assessed using the following five criteria. Each criterion will be scored separately using the rubrics below and will then contribute to the total IA score of 20%, using the following weights.

uncertainties. □ Axes are scaled appropriately.
□ Error bars are included to represent variability of data. Source of error bars is also stated as a caption and correct.
14
Selecting the appropriate graph: Line Charts or Graphs show how a particular data changes at equal intervals of time. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically.
A bar graph is a chart that uses either horizontal or vertical bars to show comparisons among categories. One axis of the chart shows the specific categories being compared, and the other axis represents a discrete value.
A histogram is a graphical display of data using bars of different heights. It is similar to a bar chart, but a histogram will group numbers into ranges. Histograms display frequency data for a value or range of values.
A scatterplot is a graph of plotted points that show the relationship between two numerical sets of data. The data may then be assessed to determine if there is positive, negative, or no correlation between data sets.
A pie chart is a circular chart divided into sectors, illustrating numerical proportion. In a pie chart, the size of each sector, is proportional to the quantity it represents – pieces represent parts of a whole.

Guide to Body Paragraph Development CEAL
“Statements that do not support the [claim] destroy the unity of a paragraph” (Hacker 24). Step—CEAL Key Questions Helpful Hints
Claim
What is a reason or subtopic that is needed to prove the thesis?
Is your claim provable? (A) Is the claim arguable?
Claims (topic sentences) are the assertions that the writer wants the reader to accept in order to accept the overall thesis.
“Readers expect to learn a ¶‘s main point in a [claim] early in the ¶“ (Hacker 31).
The claim (topic sentence) guides the reader to expect evidence.
Evidence
What support do you have for the claim? Have you properly cited the source for the evidence?
Types of support for the claim could include: facts, statistics, examples, quotations, data, etc.
What is the citation tool appropriate for this topic and discipline as assigned by your teacher (MLA, APA, Chicago Manual of Style, etc.)?
Have you used the examples of the expected citation format as you created your own citations?
Analysis
Why do you offer this piece of evidence? How does the evidence prove the claim? *** You may have more than one piece of evidence to support any claim. Have you analyzed each piece of evidence offered?
This is the writer’s own words in which reasoning shows an understanding of the connections between evidence and statement or argument.
Types of reasoning might include: reasoning by analogy, causal reasoning, inductive reasoning from specific to general, deductive reasoning from broad principle or conclusion to specific point, etc.
Link
How does the claim you make and the evidence you offer link back to the thesis or the big idea of your writing?
So what? Why does this claim & evidence matter to the big idea?
Transitional expressions can be used to show relationships, e.g. therefore, consequently, as a result, thus, then, etc.
Repeat for each body ¶ ***Variations for a body ¶ are numerous and might include – CEAEAL CEEAAL CEAAEAAL The number of body ¶s is determined by the content, purpose and audience as well as the discipline itself.
