1. Internal assessment requirements

2. What is it about?  IA consists of one individual scientific investigation  Internally assessed, externally moderated by the IB  10 hours  6 to 12 pages long  23 points  Starts today, due on december

3. How is it evaluated? Internal assessment rubric Exploration: 25% of the 1st partial grade Data collection and processing: 25% of the 2nd partial grade First draft with conclusion and evaluation: 25% of the 3rd partial grade Final draft: 50% of the quimester exam

4. What type of investigations?  a hands-on laboratory investigation  using a spreadsheet for analysis and modelling  extracting data from a database and analysing it graphically  producing a hybrid of spreadsheet/database work with a traditional hands-on investigation  using a simulation provided it is interactive and open-ended.

5. What is the objective? Although the requirements for IA are Centered on the investigation, the different types of practical activities that a student may engage in serve other purposes, including:  illustrating, teaching and reinforcing theoretical concepts  developing an appreciation of the essential hands-on nature of much scientific work  developing an appreciation of scientists’ use of secondary data from databases  developing an appreciation of scientists’ use of modelling  developing an appreciation of the benefits and limitations of scientific methodology.

6. Let´s get started… Brainstorming… What contents of Biology called my atention? …………………………………………………………………………………………………………………………………… …………………………………………………………………………………………………………………………………… …………………………………………………………………………………………………………………………………… Example: the use of DIFFERENT ORGANIC fertilizers in tomato growth

7. Research questions  Formulate questions that include a dependent and an independent variable  Example:  What fertilizer (COW HUMUS, RABIT HUMUS, OR HORSE HUMUS) IMPROVES MOST THE PRODUCTIVITY OF TOMATO PLANTS? The Independent variable is: HUMUS fertilizerS OF DIFFERENT SOURCES The dependent variable IS: PRODUCTIVITY OF TOMATO PLANTS MEASURED IN biomass (%)  What other research questions are possible?

8. Now it´s your turn…  Possible research questions: 1. …………………………………………………………………………………………………………………………… 2. …………………………………………………………………………………………………………………………… 3. ……………………………………………………………………………………………………………………………

9.  Selecting your question is the most important part of the internal assessment  The question should be:  Interesting  Creative  Open and able to generate a conflict  Allow the possibility to find sources with diffferent opinions  Insentivate curiosity and imagination

10. Once you have a research question…  Think of how you would answer this research question through experimenting or using a database.  You may need to do some research to answer this… find several reliable sources, not only from Internet.

11. Lab design: components  Title:  Includes the dependent (responding) and independent (manipulated) variables, not in the form of a question, use words such as: effect of, efficiency of, time of…  Introduction  5 paragraph essay  ackground information – research related to your subject  Justification of your reasons to make the research  Description of your dependent variable (what you will be measuring)  Description of your independent variable (what you will be varying)  What are your expectations  Cited sources (must, at least three sources)

12. Lab design: components  Research question: must mention the dependent (responding) and independent (manipulated) variable  Variables: in the form of a data table Manipulative variables (independent) Responding variables (dependent) Control (what am I going to compare against?) Constants INCLUDE UNITS What are you varying? INCLUDE UNITS, HOW IS IT MEASURED? What are you measuring? INCLUDE UNITS10, WITH DETAILS OF HOW EACH IS CONTROLLED

13.  Materials:  Listed with units and errors Procedures :  Numbered  Detailed  considers all the variables  Includes safety and ethics  Includes a data table of results (how data will be collected)

14.  Remember your due date 08-10-2015  Finish it up before the due date, remember that you will have many quizzes and projects during that week.  If it is ready, please turn it in today. If presented until Friday 18, I will print it for you.
