Teaching material analysis in Grade Two and Seven (Volume Two) and Teaching Suggestions.
(A) the target system
The learning objectives of each chapter and the summary of each chapter should echo each other; There are teaching objectives of each chapter in this teacher's teaching manual for reference. In teaching, we should pay attention to the implementation of diversified and multi-level teaching objectives, so that students can develop in knowledge and skills, processes and methods, emotional attitudes and values. Especially when preparing lessons and learning textbooks, we should dig deep into the hidden target factors in the textbooks.
To determine the learning objectives, we should pay attention to the requirements of different levels. For details, please refer to the appendix "Description of Learning Objectives" after the "Biology Curriculum Standard for Full-time Compulsory Education (Experimental Draft)". Among them, the goal of knowledge is divided into three levels: cognition, understanding and application; The goal of skills is divided into two levels: imitation and independent operation; Emotional goals are divided into three levels: experience (feeling), reaction (identification) and comprehension (internalization). Behavioral verbs should be used as much as possible to express learning objectives in teaching plans.

The main purpose of such activities is to cultivate students' observation ability and thinking ability. Attention should be paid in teaching:
(1) Preparation and rehearsal before class;
(2) Pay attention to the intuition of argument and the guidance of observation;
(3) Conditional schools can change the demonstration experiment to students' hands-on experiment, or the biology team can finish the class and the students can demonstrate it in class.
P3 detection of protein and vitamin C.
Purpose:
1. Understand the value of scientific methods and define the design of single factor and other group experiments;
2. To lay the foundation for the activity of "Exploring the Nutritional Components in Food".
Principle:
1. protein or polypeptide has a peptide bond "-CO-NH-", which reacts with CuSO4 in a strong alkali solution to generate a purple-red to purple-blue color reaction. This reaction is the same as the color reaction produced by the reaction between Cu ++ and biuret, so it is called biuret test. The reagent used is called biuret reagent, solution A is NaOH solution, and solution B is CuSO4 solution. The purplish red substance produced is "copper sodium biuret complex".
2. The blue indophenol reagent transforms the reduced Vic into oxidized Vic. Vic solution changed indophenol reagent from blue to colorless under neutral conditions; Vic solution generates indophenol under acidic conditions.
The reagent changed from blue to pink.
Precautions:
1. When preparing the egg white diluent, it should be diluted at least at the ratio of 1: 1, otherwise it will be difficult to fully react with the reagent;
2. The significance of setting up the experimental group and the control group and the similarities and differences between the two groups should be emphasized during the demonstration;
3. For the preparation and use of biuret reagent and indophenol reagent, please refer to p2~3 of this volume (indophenol can be purchased from reagent store);
4. Vic solution can be dissolved in Vic tablets or fruit juice;
5. It is best to choose liquid as the experimental material, and the color should be as light as possible. If there is precipitation, it should be filtered.

1. Understand the relationship between the molecular size of substances and dialysis bags, and then understand whether starch can be absorbed;
2. Cultivate the reasoning ability to analyze the essence (the movement of molecules through the membrane) through the phenomenon (color change).
Precautions:
1. Dialysis bags can be bought in stores, or they can be replaced by bladder membranes;
2. The teacher had better instruct the students to complete the equipment half a day in advance, and the students will demonstrate and explain in class;
3. Compare the experimental device with the absorption of digestive tract (refer to the teacher's teaching book p 1 1 in this volume).
P43 Observe the changes of arterial blood and venous blood.
Purpose:
1. Intuitively understand the color difference between arterial blood and venous blood and its causes;
2. Prove the changes and reasons of blood composition and color in blood circulation.
Precautions:
1. This demonstration experiment is relatively simple. Conditional schools can change this experiment to students' hands-on experiments and organize discussions.
2. Attention should be paid to the relationship between the color changes of arterial blood and venous blood and the changes of blood components in blood circulation;
3. This demonstration experiment can be combined with the study of systemic circulation and pulmonary circulation.

These activities are basically new content. Most experiments give questions and methods, and students draw conclusions through inquiry, so that students can gradually experience the process of scientific inquiry. Some inquiry activities are to guide students to ask questions, make assumptions, design experiments, make expectations, implement experiments, analyze results, draw conclusions and express communication. Attention should be paid in teaching:
(1) Pay attention to the organization of each inquiry activity;
(2) Give full play to students' intelligence and create a good atmosphere and conditions for students' exploration, and teachers should not do everything instead;
