The following is an example of a junior high school biology single-celled biology lesson plan: * * 1. Teaching objectives ** 1. knowledge objectives - To let the students understand that single-celled organisms can complete life activities independently. - Students will be able to give examples of the relationship between single-celled organisms and humans. 2. ability objective - Through the observation of the Paramecium under the microscope, students 'microscope operation skills will be strengthened. 3. emotion goal - Cultivate the students 'learning habits of thinking positively, taking the initiative to explore, and speaking boldly. * * 2. Important and Difficult Points in Teaching ** 1. teaching focus - Single-celled organisms could complete life activities independently. 2. teaching difficulties - The principle of single-celled organisms completing life activities independently. - Use a microscope to observe the Paramecium accurately. * * 3. Teaching preparation ** 1. experimental preparation - Paramecium culture fluid, microscope, glass slide, cover glass, dropper, magnifying glass, some cotton fiber, tweezers. 2. Teaching Coursewares. * * 4. Teaching process ** 1. to lead - Through the basic units of biological structure and function, the structure levels of animals and plants, and other knowledge that he had learned before the review, he showed the picture of the eye worm and compared it with the multicellularized organism to draw out the concept of the unicellularized organism. 2. Teaching new lessons - Common single-celled organisms - Show pictures of single-celled organisms such as bacteria, yeast, Paramecium, Amoeba, Chamaesium, and euglena to let students understand the variety of single-celled organisms. The students were guided to think about their living environment and came to the conclusion that most single-celled organisms lived in water (freshwater and seawater) or humid environments (moist soil, tree trunks, etc.), and some of them were parasitic on other organisms. They also emphasized that although single-celled organisms were composed of only one cell, they could independently complete life activities such as nutrition, breathing, secretion, movement, reproduction, and so on. - Observation of Paramecium Experiment - The purpose of the experiment was to observe the appearance and movement of the Paramecium. - He introduced the experimental materials and tools, such as the culture fluid of the Paramecium, the microscope, and so on. - Ask the students questions before the experiment, such as why they were absorbing from the surface of the culture fluid and the effect of putting cotton fibers on the droplets. - Students conducted experiments and thought about related questions, such as what could be observed with a magnifying glass, what the shape of the Paramecium looked like, and so on. The group representative reported the experiment results, the teacher commented, and finally played the experiment video. - Internal structure and physiological function of Paramecium - The picture of the structure of the Paramecium was shown. The explanation was that it moved through the cilia, and the cilia moved to make it rotate in the water and respond to external stimulation. It obtained nutrients through the mouth groove and digested food through the digestive vesicle. It discharged waste from the body through the anus and expansion vesicle. It breathed through the surface membrane. It also explained the reproduction methods of the Paramecium, including division reproduction, mating reproduction, etc., so that the students could understand that although the Paramecium only had one cell, it had the common characteristics of all living creatures and could independently complete various life activities. - Other single-celled organisms - Show a picture of Chamaematis and give a simple explanation. Let the students know that there are many single-celled organisms similar to the Paramecium. * * Reflection and Evaluation ** 1. merit - The integration of experimental teaching could help improve students 'interest in learning and hands-on ability. For example, in the experiment of observing the Paramecium, students could operate the microscope themselves and intuitively feel the shape and movement of single-celled organisms. This was better than purely theoretical teaching. - The question-and-guide teaching method could stimulate the students 'thinking ability. The questions set in each teaching link, such as the questions before the experiment, could allow the students to observe and think in a targeted manner during the experiment, and cultivate the students' scientific literacy of active inquiry. - The use of multi-media could visualize abstract knowledge by showing pictures of single-celled organisms, the structure of the Paramecium, and motion videos. It could help students better understand the concept and structure of single-celled organisms. 2. deficiency and improvement - In terms of class time control, when students were doing experiments and group discussions, there might be situations where the time was too long or too short. In the future, he could plan the time of each link more accurately, predict the possible situations of the experiment in advance, and guide the students 'reports more effectively to ensure the smooth progress of the teaching. - Students with weaker learning abilities might have difficulty understanding the internal structure and physiological functions of single-celled organisms. They could add more analogies or simplify the explanation of complex concepts in the teaching process, and provide more tutoring materials or one-on-one tutoring after class to meet the learning needs of students at different levels. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The greater the stimulus, the greater the response. This principle involved the relationship between stimulus and response. From a biological point of view, the human body's stimulus feedback mechanism included perception, transmission, processing, and response. When external stimulation acts on the human body's sensory organs (such as the eyes, ears, nose, tongue, skin, etc.), these sensory organs will transmit the stimulation signal into the nerves, and then through the neural mechanism of the nerve center to decode, select, judge, and finally output the nerve to respond to the action. During this process, if the intensity of the stimulation was greater, it might cause a stronger reaction. For example, in terms of perceptual stimulus response, when the stimulus reached a certain threshold (the critical value of the sensation), the receptor received a strong stimulus, which would cause the human body to produce a more obvious physiological and psychological reaction. For example, when one heard a sudden loud noise (a loud stimulus), the human body would have a strong panic reaction, such as a rapid heartbeat, high muscle tension, etc. This was because the perceptual neural network in the brain made corresponding adjustments to this kind of high-intensity stimulus. The same was true for emotional stimulation responses. When people experienced relatively strong emotional stimulation, such as extreme anger, this large emotional stimulation would make the facial muscles tense more, the heart rate faster, and the emotional agitation stronger. This was regulated by the emotional center and the autonomous nervous system. There was a similar phenomenon in the field of consumer behavior. If a brand gave consumers strong enough stimulation (satisfying certain stimulation conditions, such as the length of stimulation, repetition, intensity, simplicity, compound feeling, etc.), it might cause a greater reaction from consumers, such as making consumers have a deeper impression of the brand or prompting them to make consumption decisions. In addition, from the perspective of conditioned reflex in psychology, through repeated conditioned and unconditioned stimulation, if the intensity of the stimulation is greater, the response to the conditioned reflex may be more intense. For example, if a brand is often associated with children's health with high-intensity publicity (greater stimulation), it may make consumers think of children's health more naturally and strongly when they see the brand. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
