6. The most common use for fluorides is in toothpaste, preventing tooth decay. It is also put in water for the same reason (Importance and uses). It is also used for Teflon pans, water proof clothing and helps make detergent. Teacher comment to student was: states (Level 1-2). This states a benefit (Level 1-2). explain(Level 5-6) To explain it (Level 5-6) we need to know how fluorides do this. * * FOR MORE DETAILED EXPLAINATION LOOK AT APPENDIX A.

7. One common biological use of chlorine is food preservation. The reason for this is because micro organisms like bacteria, or fungi, cannot survive with too much NaCl. With too much NaCl osmosis happens in a way that hurts the micro organism’s cell because now water is drawn out of the micro organism’s cells. Teacher comment to student was: Excellent – this is what we mean by EXPLAIN the benefits. * * FOR MORE DETAILED EXPLAINATION LOOK AT APPENDIX A.

8. Chlorine is also used in many other household appliances including; bleach, computer hardware, plastics, textiles, paper and many more. Teacher comment to student was: STATEMENT (level 1-2) DESCRIBE (level 3-4) or EXPLAIN the science behind (Level 5-6). Notice that this is a STATEMENT (level 1-2) To get a higher grade, the task sheet says you must DESCRIBE (level 3-4) or EXPLAIN the science behind (Level 5-6). * * FOR MORE DETAILED EXPLAINATION LOOK AT APPENDIX A.

11. Halogens are non- metals and are found in group number seventeen on the periodic table. The real name for halogens is “salt-makers”. This is because, every compound that contains a halogen is a salt. Halogens can help us greatly and widely but, they can also be very harmful. I will talk to you about the effects of one particular halogen, chlorine. I will talk about the good and the bad uses and effects of chlorine and from that, base my opinion on if the manufacture of halogens and their compounds should be banned. Teacher comment to student was: It is good that your intro paragraph clearly states what the whole essay is about. With more experience you will find a way to write this without the phrase “I will talk about..”

16. Max. Achievement level Level descriptor 6 The student states a clear focused problem or research question, formulates a testable hypothesis and explains the hypothesis using scientific reasoning. The student selects appropriate materials and equipment and writes a clear, logical method, mentioning all of the relevant variables involved and how to control and manipulate them, and describing how the data will be collected and processed. The student evaluates the method, commenting on its reliability and validity. The student comments on the validity of the hypothesis based on the outcome of the investigation. The student suggests realistic improvements to the method and makes suggestions for further inquiry when relevant. Criterion E: Processing data Criterion D: Scientific inquiry Max. Achievement level Level descriptor 6 The student collects sufficient relevant data and records it in a suitable format.

19. The International Academy - Amman Done by Science Department Thank you

23. Problems to avoid 1. neither of these two are ‘cited’ in the essay; put them in Bibliography 2. Double space 3. Indent second line and subsequent lines so it is easy to see the source name 4. Match the source identification with what you put in parentheses for the in-text citation so it is very easy for the reader to find the source in the list.

26. Test Section Style of questions Section A: Recall of information Multiple choice questions. Single-answer recall questions. Close questions. (Short –answer questions). Section B: Application of knowledge to solve simple problems. Simple equation application questions. Questions that require a simple grasp of content and skills to answer them. Section C: Application of knowledge to solve familiar problems. Questions are modelled on questions that students have had previous exposure to through assignment work, book work, etc. Section D: Analysis of scientific information. Requires a source of data to analyse i.e. table of data, equipment readings, and/or graphs of data. Questions require students to either:  make predictions,  outline and/or explain the underlying trend/pattern using conceptual understanding,  derive the mathematical relationship/model that describes the pattern/relationship,  discuss the reliability and/or validity of the data and the ability to extrapolate from it. Section E: Application of knowledge to solve unfamiliar problems. Requires questions that the student has not been exposed to previously OR Questions that require the student to use their knowledge in a way they have not done before Section F: Evaluation of scientific information. Questions MUST require the student to make a judgement/evaluation about scientific information AND explain their reasoning using their scientific knowledge and understanding to justify their choice. Questions could:  present a scientific theory/concept or scientific knowledge and ask the student to explain if it is correct/accurate OR how accurate it is or not using their understanding,  present two sides of a conceptual argument and get the student to evaluate who is correct and explain why using their understanding,  the science underlying an application is outlined/explained and the student has to evaluate if it is correct and explain why/why not using their understanding. Appendix C - What style of question goes in what section?
