Unit Test 8: Circulatory, Lymphatic and Excretory systems- IBO Grade

for Criterion C

Level 1-2: Level 1-2 questions require simple recall, matching and simple selection.

LEVEL 3-4: These are more difficult questions - students may still need to recall but also need to justify or argue their reasoning. More thanmemory is required for most of them.

LEVEL 5-6: Application of knowledge to solve familiar problems. Students will be able to answer parts of these questions, butfor them to be ranked at a 5-6 level, their answers need to show the qualities associated with Criterion 5-6 on the rubric.

MYP Guide Descriptor

The student does not reach a standard described by any of the descriptors below.

The student recalls some scientific ideas and concepts and applies these to solve simple problems.

The student explains scientific ideas and concepts and applies scientific understanding to solve problems infamiliar situations. The student analyses scientific information by identifying parts, relationships or causes.The student provides an explanation that show understanding.

The student explains scientific ideas and concepts and applies scientific understanding to solve problems infamiliar and unfamiliar situations. The student analyses and evaluates scientific information by makingscientifically supported judgements about the information, the validity of the ideas or the quality of the work.

What do I have to do?

Forget everything you've studied.

Correctly answer simple vocab, multi-choice or labelling questions.

Level 1-2 plus:- give correct, longer-answered(explained) answers, showingunderstanding, not just memory.- Solve problems that you may haveexperienced before (or similar).Levels 1-4 plus:- Apply your knowledge to solvingproblems in a new context.- Analyse and evaluate informationpresented to you, supporting youranswers with scientific knowledge andjudgement.

Understanding the assessment criteria:Successful completion of multiple choice and Ql will result in level 2 being awarded.

Successful completion of Q3, Q4 and Q5 will result in level 4 being awarded.

Successful completion of Q2. Q6 and IB question will result in level 6 being awarded.

To gain higher marks, all requirements of earlier sections must be fulfilled!

•You need to identify which sample was taken from the radial artery and which sample was tajjie'n from thefemoral vein. Match samples X and Y with the correct blood vessel and justify your answer/In youranswer include an explanation about why the concentrations of oxygen (O2) and carbon dioxide (CO2)vary depending on the bloodvessel from which the sample was taken.
