MYP 3 Science Criterion A: Knowing and understanding Unit title: ___________________ Statement of inquiry: __________________. Name: The questions in this test will be used to give you a criterion A level, it is divided into three sections. • Section A: two questions that will assess how you explain your scientific knowledge. • Section B: two questions that will assess your application of scientific knowledge and how you use it to solve problems. • Section C: two questions that will assess the way you analyse and evaluate information to make scientifically supported judgments. Each question is designed to be hierarchical, this means that as you answer each question you will find it will get progressively more difficult. You should attempt all of the questions. Level Questions 1-2 3-4 5-6 1 Section A 2 3 Section B 4 5 Section C 6 You have achieved a level: Reflection: What could you do next time to improve your achievement level? 7-8 Section A: Question One i. explain scientific knowledge This question is about Human digestive system Level 1-2 a. i) Select ____ (perhaps a matching or T/F type of question or from a list) ii) Select ____ iii) Select ____ Level 3-4 b. i) Recall ______ ii) Recall ______ iii) State ______ Level 5-6 c. i) State ________ ii) State ________ Level 5-6 and 7-8 d.

Apply the information provided to answer the following questions. Make sure to support your answer with scientific reasoning. *Provide students with information with which they can make judgements, perhaps a graph that you help interpret for them. i) ii) iii) iv) v) Level 5-6 and 7-8 b. Apply the following information, and interpret the statements. i) ii) iii) iv) v) Section C: Question Six iii. analyse and evaluate information to make scientifically supported judgements In this question you must interpret, analyse, and evaluate data to make supported judgements about _____________ Level 1-2 and 3-4 a. Apply the information provided to answer the following questions. Make sure to support your answer with scientific reasoning. *Provide students with information with which they can make judgements, perhaps a graph that you help interpret for them. i) ii) iii) iv) v) Level 5-6 and 7-8 b. Apply the following information, and interpret the statements. i) ii) iii) iv) v) The table shows the energy requirements of different groups of humans. 1. State two processes in human cells which require energy. 2. Suggest a reason for increasing energy requirements as boys grow older. 3. a) Calculate the percentage increase in energy requirement for a 14–15-year-old boy that stops playing computer games and starts training with a football team. b) Explain how the extra energy is used in the boy’s body. 4. Explain what will happen in a boy’s or girl’s body if: a) they eat food each day containing more energy than their requirement b) they eat food each day containing less energy than their requirement. 5. a) State the trends in energy requirement as boys and girls grow from 15–16 to 17–18 years old. b) Suggest a reason for the different trends in boys and girls. 6. Draw a bar chart to display the energy requirements for moderately active boys and girls, for all boys or for all girls. What is energy needed for in cells? i Write the word equation for photosynthesis. [2] ii Explain the importance of photosynthesis in food webs. [3] b Leaves need water in order to carry out photosynthesis. Fig. 5.1 shows a root hair cell, which absorbs water from the soil. Fig. 5.1 i Describe how the root hair cell absorbs water by osmosis. [3] ii Water is transported from the roots to the leaves through tubes made of dead cells. Name these dead cells [1] Rice contains large amounts of starch. In the human digestive system, starch molecules are broken down by enzymes to produce glucose. Glucose is then absorbed into the blood. i Name one part of the digestive system in which starch is broken down by enzymes. [1] ii Name the part of the digestive system in which glucose is absorbed into the blood. [1] Identify the part that absorbs the food. 1 (a) Fig. 1.1 is a diagram of the human digestive system. Use the letters from Fig. 1.1 to complete Table 1.1 to give the part of the human digestive system that is identified by each function. Write one letter only in each box. You may use the same letter more than once. There are some letters that you will not use. The first one has been done for you. Table 1.1 function letter Peristalsis B Protein digestion Insulin production Partially digested food is mixed with bile Most water is reabsorbed The human diet provides nutrients for the synthesis of biological molecules that make up cells, cell products and tissues. (b) (i) Complete Table 1.2 to show the nutrients that are absorbed from food to synthesise the large molecules listed.
