Biology lessons. Preparing for the exam: how to learn biology yourself at home from scratch Learning biology from scratch

The role of biology is enormous in our world. Although it is not one of the priority subjects, most schoolchildren and parents consider it “superfluous”. At the same time, to obtain a medical education, a good knowledge of biology is a priority. We are not talking about the quality of teaching a subject at school - we are talking about the attitude of the majority of students towards this discipline, which does not have the best effect on learning the material. Although extremely important.

Biology - the science of living nature

Biology is a subject that requires perseverance and attention, so individual lessons are essential to understand its content and in preparation for further education. Video lessons from the educational portal will help your child learn the school curriculum more effectively, consolidate what he has learned and acquire additional knowledge in the field of botany, zoology, and the cellular structure of plants and organisms - from protozoa to humans. Knowledge of the topics of biology lessons gives the student an understanding of not only physiological and biochemical processes, but also makes him understand what “life” is in general.

Starting to study botany and role of biology in the 6th grade, schoolchildren must understand the role of plants in the life of not only humans, but also the entire planet, learn about their diversity and distribution, and become familiar with the structure of plants and their individual parts. The duration of video lessons on botany topics is short and takes into account the age characteristics of the child, but the quantity and quality of information offered by teachers will ensure a high level of knowledge. The student has the opportunity to access any section of the program as many times as he or she needs. So biology methods can be mastered very quickly.

In the 7th grade, students move on to the study of living organisms, starting with the simplest spineless species, insects, aquatic fauna, and ending with terrestrial animals. At this stage, schoolchildren gain an understanding of how an animal cell differs from a plant cell, the world of insects, the basics of species classification, etc. The purpose of the series of video lessons for the first two years of education is, first of all, to awaken children’s interest in the living nature around us, to teach them to understand and take care of it.

Biology is the first stage of knowledge for a future doctor

Starting from 8th grade, biology topics Day by day they become more complex and difficult to understand. The study of the human body and the most complex branches of biological science begins - genetics, cytology, selection, physiology. It is very difficult to explain such complex things in an understandable language, but the experience of teachers who conduct video lessons on these topics allows us to achieve our goals.

Biology is not a speculative science. In order to achieve success in it, you need to know, which consist of several concepts - observation, experiment and analysis. In this sense, biology is an analogue of physics, only in the sphere of living nature, and is just as difficult to study and understand. Individual lessons with the help of video lessons, the presence of a minimum experimental base and the desire for knowledge will be the first steps towards obtaining a medical education.

The 11th grade program is dedicated to methods of biology on evolutionary theory and a review of scientific disciplines that arose at the intersection of biology and other sciences, such as bionics, ecology, etc. For students who want to go far beyond the school curriculum, the educational portal offers a series of optional video lessons, which outline various sections of biological science in more detail .

Biology, as the fundamental science of life on Earth, should, from the first lessons, become for students the most interesting subject with great research potential, which over time turns into the main incentive for the conscious evolution of individual knowledge. To properly prepare for biology, today it is not enough for a teacher to have high-quality lesson notes and the necessary equipment - each lesson requires additional visual aids and fascinating supporting information on each topic of the biology course. Therefore, educational videos with notes from biology lessons, which will be discussed below, can help not only the student, but also the novice teacher to structure a lesson correctly, skillfully select teaching aids and glean various entertaining information on a specific topic.

The meaning of biology as a science is very important, because knowledge of the historical development of the organic world, the patterns in the structure and functioning of living systems of various kingdoms and subkingdoms, their interrelations, stability and dynamism plays a vital role in the formation of the materialistic worldview of each person, as well as in the compilation of a general scientific picture of the world.

Study in different classes

Preparation for the exam in this subject includes coverage of all the material covered over six years, therefore the teaching of 6th grade biology lessons should be conducted with a focus on periodic repetition of the topics covered. At the same time, the initial biology topics in the 6th grade, which cover such fundamental concepts as the cell, cell structure, tissue, should be as interesting as possible for inquisitive students, which will subsequently help develop a subconscious craving for the subject. This interest is fueled primarily by experiments and research conducted both in school classrooms and at home. Since many of the objects that this discipline studies are literally at hand, it is precisely this circumstance that the teacher must take full advantage of.

Of course, today no biology video can completely replace the process of traditional learning in school lessons, but these materials are quite capable of playing the role of convenient and effective auxiliary tools for the educational process. And who knows, maybe over time, with the further development of Internet technologies, distance learning will become a successful alternative to school lessons, which will allow most topics in biology or study any other subject remotely. On our portal you can study biology for free , with only Internet access .

It is important to note the humanitarian importance of biology, which consists in developing environmental thinking in a modern schoolchild, the essence of which is realizing oneself as a part of nature.

Biology is not the easiest subject, but studying it should not turn into a punishment. In biology, one concept comes from another, so it is important to understand the basics before moving on. Learn biology-related vocabulary and review study material thoroughly to better understand the subject and prepare for a test or exam.

Steps

Part 1

Try to have a positive outlook on biology. Of course, it is a difficult subject, but it is very interesting, especially if you think about what you have already learned through biology. Having the right positive attitude is essential to having fun learning biology. Of course, this will not make the subject easier, but you will no longer feel such a load.

• Think about how your body functions. How do your muscles work in sync to allow you to move? How does the brain communicate with these muscles so you can take a step? It is very difficult, but everything in our body is interconnected - it is this connection that allows us to stay healthy.
• Biology teaches us to understand these processes and how they are carried out. If you think about it, learning this subject will be much more interesting.

1. Break difficult words into several parts. Many biological terms may seem difficult to remember. However, most terms and concepts come from the Latin language and have a prefix and a suffix. Knowing the prefixes (prefixes) and suffixes that are included in a given term, you can correctly read this word and understand its meaning.

   To learn terminology faster, make flashcards. Flashcards are one of the best ways to remember and understand many of the words you'll encounter in biology. You can carry the cards with you and learn these words anywhere. For example, you can do this in the car on the way to school. In addition, the process of creating flashcards is a useful way to learn new words. The way to learn new words using flashcards is very effective.

   • At the beginning of each new topic, find words whose meaning you do not know and write them down on cards.
   • Throughout the topic, repeat and learn these words, and by the time of the exam or test you will know them all!

2. Draw and draw. A diagram of a biological process is much more effective in helping to understand and remember it than just text. If you really understand the process, you can draw a diagram and label the main elements. Also pay attention to the diagrams and pictures in the textbook. As you read the title and explanation of the diagram, try to understand how it relates to the process you are studying.

   • Many topics in biology begin with the study and review of the structure of the cell and its organelles. Try to draw a cell and label its main organelles.
   • The same applies to different cell cycles, for example, ATP synthesis (Krebs cycle). Draw this process several times a week to learn it before the exam.

3. Read the topic again before class. Biology is not a subject that can be understood a few minutes before class. Read new material before you discuss it in class to better understand its content and understand what is being discussed. You will understand and remember much more if you come to class with questions ready about a new topic.

   • Find out what topics are on the curriculum so you can read them before class.
   • Write notes and notes about the new material and come to class with questions prepared in advance.

4. The study of biology is based on the concept of general to specific. To understand biology, you need to have a basic understanding of its various aspects before going into more detail. That is, before trying to understand individual mechanisms and processes, you need to master the topic in general.

   • For example, you need to know that DNA is the template for protein synthesis, and only then should you try to understand the mechanism by which the DNA sequence is read and converted into protein.
   • Write a summary, organizing topics and concepts from general to specific.

Part 2

1. Answer the questions at the end of each chapter. Biology textbooks have some really helpful questions that help you reinforce concepts from the topic you just read. Try to answer the questions and check if your answers are correct. Pay attention to those questions that are difficult for you to answer. Reread your notes or chapters that discuss these issues.

   • If you still could not answer some questions, be sure to ask your teacher for help.

2. At the end of each lesson, reread your notes. You can’t leave a lesson and immediately forget everything you just learned. If you read your notes that same day or the next day, you will be much better able to remember and understand what was discussed in class. As you review your notes, think about whether everything is clear to you.

   • If you get distracted by something, read the material on this topic again in the textbook. If you still don't understand, ask your teacher to explain it to you in class.

3. Take time to study biology. Because biology is difficult to understand, try to take the time to study it. If you study a little every day, it will become a habit. Later, you will thank yourself for your efforts, because you will not have to study everything at once for the exam, because you will gradually study everything over the course of the semester.

Biology is familiar to all of us from school. Its study is long and painful - somewhere from the fifth or sixth grade and ad infinitum (if a student at the university needs to study this subject). But the task of quickly learning biology comes when a student is preparing for an exam.

We have prepared for you some useful tips on how to quickly learn a table, paragraph, retelling or any topic in biology.

6 ways to learn biology quickly

1. Review biology questions for the exam/test. Cross out the ones you know well. Use a marker of the same color to mark those that you know partially. Use a marker of a different color to mark those questions that are completely unknown to you.

Do you know that…

Is the bite of a hamster much worse than the bite of a stronger and larger animal? And all because of its thin and long teeth, which diverge in different directions during a bite. As a result, the wound is not only deep, but also torn and quite painful.

1. When studying an unfamiliar or incomprehensible topic, the main thing is to remember the essence. Then restate the question in your own words, and only then try to grasp the finer details. Writing down (at least briefly) the main points will allow you to quickly master the material.
2. Write complex terms and definitions on a separate sheet. Learn not only the meaning of the terms themselves, but also how to use them to solve biological problems. Try to retell each term in your own words.
3. You can remember terms quite quickly. First, remember that they all come from the Latin language, which has basic suffixes and prefixes. These suffixes and prefixes are repeated quite often. Therefore, knowing their meaning, you will quickly understand the meaning of even a new long and incomprehensible word.

Do you know that…

Do ants also have different professions? For example, among them there are even surgeons who treat patients in a room specially designated for this purpose. First, the surgeon examines the victim, then dresses the wound and treats it with a special clear liquid from his own mouth. Agree, it’s quite convenient, because you don’t need to run to the pharmacy to get your medicine!

1. When studying questions for the exam, be sure to write cheat sheets. Moreover, you must write it yourself and by hand - this uses mechanical and visual memory.
2. Frequent breaks help you absorb information much faster than taking study breaks every hour or two. Ideally, short breaks should be taken every 20 minutes. And try to go out into the fresh air for at least 5 minutes every hour. During this time, the brain has time to saturate itself with oxygen and rest in order to continue productive assimilation of information.

Here's a video for those who want to get a general idea of ​​biology:

Agree - quite simple tips that will help you quickly prepare for a biology exam or even learn this subject from scratch. Well, if this doesn’t help, don’t worry. There are always people next to you, ready to lend a helping hand and provide support at any time.

How to quickly memorize complex biology material?

The answer immediately suggests itself - “memorize” and that’s all! And it seems that you can do this, but everyone who has “crammed” something at least once in their life will agree that this method cannot be called fast at all, and the material memorized by heart “flies” out of your head as soon as you stop repeating it it at certain intervals.

When studying biology, you may be faced with the fact that there is a lot of material to prepare for the exam (zoology, botany, anatomy, and general biology - it’s crazy!), but there is no time for unproductive memorization. Therefore, we will try to figure out how to learn effectively and remember, if not for life, then at least before the exam.

First, a little theory. Our brain is an amazing organ that can accommodate a huge amount of information. The questions “What is memory and what is its nature?” people have been interested since ancient times, and today there are many scientific institutes in which the still unsolved mysteries of our brain are actively studied. At the moment, much is already known about the brain and the processes of memorization, for example, that memories are not stored in any one or several departments, but are scattered throughout a system of neural connections. The limbic system of the brain, located on the inner surface of the temporal lobes, plays a key role in the process of memory. The hypothalamus is also located here, an important structure for memory formation.

Now comes the fun part! In order to remember a lot and quickly, you can use certain memorization methods, they are called mnemonics techniques, and they are actively used by people whose field of activity is associated with large amounts of information.

1) Let's start with a simple technique - composing a semantic phrase. Suppose you need to remember the classification of the kingdom Animalia.

Kingdom, phylum, class, order, family, genus, species.

The Royal Tower Whoever opens it will immediately return as a Knight.

Geological periods can be remembered with the help of a humorous phrase: Every Excellent Student Should Smoke Cigarettes; You, Yura, Mal - Drink Tea at Night: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, Paleogene, Neogene, Quaternary.

Let's also try to remember the cause of suffering for all first-year medical students - 10 pairs of cranial nerves!

Onegin - Olfactory

Knows - Visual

Where - Oculomotor

Was – Blokovy

Tatiana - Trigeminal

He is the Averting Eye

Flies - Facial

Arrow - Auditory

Tongue - Glossopharyngeal

Hanging out - Wandering

Before - Additional

Heel - Sublingual

In this way you can easily remember eras, essential and non-essential amino acids or the composition of gastric juice. By the way, about gastric juice! This has been my favorite biological phrase since school, I think it will be useful for you too:

Pepsin PEPPI

Khimosin Sly

Gelatinase YELLOW

Lysozyme Fox

2)Reception of composing a word also quite easy to use, for example, you want to remember the sequence of phases of mitosis: prophase. Metaphase, anaphase, telophase... Let's simplify our task! Using the first letters, we’ll make up the phrase “Put MAT” and now we’ll definitely not forget who’s behind what!

3) The next technique is a little more complicated, but it’s also a lot of fun to use! Rhyme technique. This time we will remember animal tissues: epithelial, connective, nervous, muscle. Let's compose the verse according to the first letters: This king insolently the enemy, Sends me on the run again!

4) The technique of forming semantic phrases will help us remember the circles of blood circulation. Let's try! The systemic circulation begins in the left ventricle and ends in the right atrium. For better memorization, we use the phrase:

“THE BIG LION WANTS TO RULE THE COURTIERS”

And in the pulmonary (pulmonary) circulation from the right ventricle and ends in the left atrium. Again, let’s make up the phrase: “THE LITTLE PRINCE WISHES LOVE TO THE COURTIERS.”

It is much easier for our brain to remember associations and funny rhymes than a pile of complex material, so the more original and funnier your associations are, the faster even the most complex topics will be remembered! Biologists, by the way, are very original people, and they even memorize the Krebs cycle in the form of a poem about a pike, so mnemonics is also a creative approach to the subject! Benjamin Franklin wrote: “Many people complain about memory, almost no one complains about intelligence,” so let’s learn to remember, and not “cram,” and you will be happy in all subjects!;)

Good luck in acquiring new knowledge, interesting studies and high scores in exams!
