How to write a scientific experiment report?

Scientific experiment report: preliminary work

Experimenter: Wu,, Dafang,

Theme: Plants and Environment

Experimental date: September 26th, 2005.

Experimental scheme: 1, specifying the plant name;

2. Investigate the living environment of plants:

① See whether the soil is dry or wet;

(2) Whether plants need sunlight;

3 plants need to be in a cool place or a dry and hot place;

④ How much water should be poured; Do you need enough water? )

⑤ When watering, whether to water the page or the root;

6. What is the ambient temperature for plants to live?

Specific embodiments: (corresponding to the above)

(1) Grab a handful of soil near the plant and touch it.

If it is dry, it should be hard (sometimes spherical) and make a sound when mashed;

If it is wet, it should be soft and sticky.

Find two identical plants, one in the shade and the other in the sun, and see which grows better!

③ (The method is the same as ②)

④ You can see the quality of the surrounding soil. If it is wet, you can know to water more.

⑤ You can consult the gardener's master and ask him how to water it; Or, we can see if there is water on the leaves. If there is water, we can know that it is watering the leaves.

⑥ (The method is the same as ⑥)

Scientific experiment report: experimental results

Experimenter: Wu,, Dafang,

Theme: Plants and Environment

Experimental date: September 26th, 2005.

Actual results:

First of all, pine trees

1, the soil is very dry;

2, basically need sunshine. After observation, we found that pine trees would grow better and bigger if there was sunshine. If there is no sunshine, pine trees will grow very short and most pine branches will wither;

3. Grow in a cool and hot place;

4, do not need enough water, because pine trees are drought-resistant and cold-resistant, and do not need to be watered frequently;

5. Water the roots when watering;

6. The temperature is about 27~28 degrees.

Second, pomegranate tree

1, the soil surface is dry, but it is still wet inside;

2. They need plenty of sunshine;

3. Adult trees don't need watering;

4. Water the roots when watering;

5. The temperature is about 28 degrees.

6, small discovery: pomegranate is very red in the sun, but it is cyan or yellow in the shade.

Summary: There are all kinds of flowers and trees in the world, and different plants need different growing environments.

Why is it so hot!

Because it's summer!

The main content of creating class physical environment

The basic skills mainly include the use of instruments, the design of experiments, the query of tables and the knowledge of drawing. The specific contents are as follows:

Correct use of scales, pallet scales, spring scales, measuring cylinders (or measuring cups), pulleys and pulley blocks, thermometers, ammeters, voltmeters, sliding resistors, etc.

Density, mechanical efficiency, resistance and electric power can be measured as required.

You can check the density table, melting point table, boiling point table, etc.

Be able to make diagrams, complete light path diagrams, connect physical drawings from circuit diagrams, or draw circuit diagrams from physical drawings.

Does the external environment have a great influence on the conclusion of physical experiments?

Have a great influence. So there is the so-called ideal experiment and the so-called error analysis. Personally, the most basic law is often not what we see in reality, but what we idealize. If we use experiments to verify these laws, we should consider the influence of various factors in each reality on the experiments.

How to optimize the physical and psychological environment of classroom teaching

The optimization strategy of physics classroom teaching aims at completing physics teaching tasks, improving students' quality and cultivating students' innovative spirit and practical ability. The quality of physics teaching depends to a great extent on the effective implementation of physics classroom teaching strategies. Here, the author discusses the optimization strategy of physics classroom teaching in middle school.

First, optimize the interaction between teachers and students in physics classroom teaching

The Outline of Basic Education Curriculum Reform (Trial) points out that "teachers should actively interact with students in the teaching process and develop together". Educators, psychologists and sociologists at home and abroad have done a lot of research on teacher-student interaction. However, in the past, there were more studies on classroom teaching interaction under the background of economic development and high education level, but less on classroom teaching interaction under the background of underdeveloped education. This kind of research is of weak guiding significance to underdeveloped areas. To improve the quality of the whole people and promote quality education in an all-round way, we cannot ignore the curriculum reform of basic education.

1. Current situation of physics classroom teaching

Due to the constraints of family, school and social conditions, students in mountainous areas have a shallow knowledge and a narrow knowledge. Most of them are introverted, timid and talkative, and students are often in a passive position. The main battlefield for students to accept physical knowledge is the classroom. At present, most teachers in the classroom are mainly teaching, and students are rarely allowed to acquire knowledge and development through their own activities and practices; There are few learning activities that rely on students to consult materials and discuss collectively; Teachers often assign written exercises and reading textbooks, and rarely assign practical assignments such as observation, production, experiment, reading extracurricular books and social investigation. Students rarely have the opportunity to express their views and opinions according to their own understanding. To a certain extent, classroom teaching still has the situation of "classroom-centered, teacher-centered, textbook-centered". Ignoring the cultivation of students' innovative spirit and practical ability. A large number of studies show that learning style is closely related to learning results. At present, the way students participate in classroom teaching in China affects the learning effect. Simple behavior participation can not promote the development of students' advanced thinking ability. Only the learning style with positive emotional experience and deep cognitive participation as the core can promote the improvement of students' all-round quality, including high-level thinking.

2. Analysis of the factors affecting the interaction of physics classroom teaching in junior high school.

(1) Lack of hardware facilities

Nowadays, many researches on teacher-student interaction mostly use multimedia technology to obtain information and realize network interaction. However, the school where the author is located is limited by financial resources, and the current hardware facilities cannot realize network interaction, and there are not a large number of books for students to consult. At present, the way for students to acquire knowledge here is mainly in the classroom, but there is very little knowledge taught in the classroom, and most of the knowledge needs students to consult books and learn by themselves. Moreover, physics is a very practical subject, which requires a lot of experiments, especially for students to experience it themselves. However, due to the lack of funds, the school where the author works can only meet the needs of teachers to do demonstration experiments at most.

(2) Traditional teaching concepts, teaching methods and learning methods.

Traditional basic education is weak, and the traditional education mode is still adopted, that is, teachers talk more and students have less activities; A lot of injections are used, but few are really enlightened. Most of the students' learning methods are passive acceptance, rote memorization and copying the knowledge told by teachers or books. This kind of cramming teaching mode, with heavy academic burden, often leads to students' weariness of learning, rigid thinking mode and lack of innovative spirit. In order to promote quality education in an all-round way, the most important thing now is inquiry learning under the guidance of constructivism theory. Moreover, the traditional concept is to emphasize scores over ability, which brings difficulties to the interaction between teachers and students.

(3) Influencing factors of students' psychological quality.

Due to the constraints of family, school and social conditions, most students are not confident enough, their psychological quality is not good enough, and because of the influence of family economy, their psychological burden is too heavy, so they can't devote themselves to their studies. On the other hand, because students rarely answer questions since childhood, students are often in a passive position in long-term traditional education, and this repressed "humanity" is even more serious in junior high school, which makes the classroom atmosphere depressed and brings difficulties to the development of teacher-student interaction activities. Especially for the seventh grade students, a large number of students still maintain the psychology and learning methods of primary school students, and have not yet reached primary school to junior high school. ......

How to write the error analysis of college physics experiment report?

Mainly to analyze uncertainty.

There are two kinds of uncertainties: A and B, so I won't go into details. There are about ten pages in the textbook. . Turn over the books by yourself.
