Fifth grade elementary school, Jiangsu education edition, science cloud and fog
Clouds were visible suspended bodies formed by the condensation or sublimation of water vapor in the air. They were composed of a large number of small water droplets, supercooled water droplets, ice crystals, or a mixture of them. Its formation condition was that the air was rapidly pushed up by the ascending airflow. The air pressure was low, and the air expansion consumed heat, causing the temperature to drop (the temperature dropped by about 1 ° C for every 100 meters of dry air rise). As the temperature dropped, the water vapor became saturated. The water vapor attached to the condensation nucleus and condensed into cloud droplets. A large number of cloud droplets combined together and were suspended in the air by the ascending airflow to form clouds. Fog and clouds were actually the same thing, but they were in different locations. The fog was close to the observer's position, and the clouds were far away from the observer's position. On the mountain, it was often difficult to distinguish between clouds and fog. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Elementary school fourth grade first volume western normal university edition mathematics question
The following is some of the content related to the fourth grade mathematics questions: ** 1. Unit Conversion ** 1. ** Conversion of length units ** - For example, how many decimeters was 3 meters? According to 1 meter = 10 decimeters, 3 meters = 3×10 = 30 decimeters. - How many meters was 500 centimeters? Since 1 meter was equal to 100 centimeters, 500 centimeters was equal to 500 divided by 100 = 5 meters. 2. ** Area Unit Conversion ** - How many square decimeters was 2 square meters? 1 square meter = 100 square meters, 2 square meters = 2×100 = 200 square meters. - How many square meters is 30000 square centimeters? Since 1 square meter = 10000 square centimeters, 30000 square centimeters = 30000 divided by 10000 = 3 square meters. ** 2. The classification of angles and related calculations ** 1. ** The degree of the angle is determined ** - Give the degree of an angle and determine what angle it is. For example, an angle of 35° was an acute angle because it was greater than 0° and less than 90°. - For an angle of 120°, since it was greater than 90° and smaller than 180°, it was an obtuse angle. 2. * * Calculating the relationship between the number of horns ** - Given a circular angle, how many right angles is it equal to? Because 1 circle angle = 360°, 1 right angle = 90°, so 1 circle angle = 360° × 90° = 4 right angles. ** 3. Relationship between quantity (unit price, quantity, total price; speed, time, distance)** 1. ** Relationship between unit price, quantity and total price ** - Knowing that the unit price is 5 yuan, the quantity is 8 pieces, asking for the total price. According to the unit price x quantity = total price, the total price = 5 x 8 = 40 yuan. - If the total price is 60 yuan and the unit price is 10 yuan, ask for the quantity. From the total price divided by the unit price = the quantity, it can be seen that the quantity = 60 divided by 10 = 6. 2. ** Speed, Time, Distance Relationship ** - Speed: 12 m/s, Time: 5 seconds, Distance: According to the speed x time = distance, the distance = 12 x 5 = 60 meters. - The distance is 80 kilometers, and the speed is 20 kilometers per hour. From the distance/speed = time, it could be seen that time = 80/20 = 4 hours. ** 4. Rectangle and Square Area Classes ** 1. ** Rectangle Area Calculation ** - Given that the length of the rectangular shape is 8 cm and the width is 5 cm, find the area. According to the area of the rectangular shape = length x width, the area = 8 x 5 = 40 square centimeters. - If the area of the rectangular shape is 48 square meters and the width is 6 meters, find the length. From the length = area/width of the rectangular shape, it could be seen that the length = 48/6 = 8 meters. 2. ** Square Area Calculation ** - The side of a square is 7 decimeters. Find the area. According to the square's area = side length x side length, the area = 7 x 7 = 49 square decimeters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Jiangsu Education Version Elementary School Science Fifth Grade Volume 1 Our Brain
The unit "Our Brain" in the fifth grade elementary school science textbook of Jiangsu Education Press adopted a cognitive structure that was organized in the order of "stimulation and response → brain structure and function → protecting the human brain". In terms of the structure of the brain, the adult brain weighed about 1400 grams, which accounted for about 80% of the human brain. The size of the brain could be experienced by clenching two fists together. Its shape was similar. The surface of the brain was like a walnut, with many concave grooves and bulging folds, which greatly increased the surface area of the cerebral hemisphere. The brain was divided into two halves, which were as hard as tofu. The brain had a variety of functions, including memory function, such as looking at a picture for ten seconds, closing your eyes and remembering the items on the picture; emotion recognition function, such as recognizing fear, happiness, anger, sadness, and other emotions; movement control function, the brain's management of the human body was a kind of intersecting relationship. The left hemisphere dominated the movement of the right side of the body, while the right hemisphere controlled the movement of the left side of the body. At the same time, the left hemisphere focused on managing language and other functions, while the right hemisphere focused on managing spatial concepts and other functions. There were also creation functions. This unit would also involve the process from stimulation to response, as well as the development and utilization of the brain. It would allow students to have an in-depth understanding of the brain from many aspects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Prepare for the rubber band jump ** 1. ** Selection of venue ** - It was better to choose a flat and not too hard ground, such as a lawn. It was better to avoid cement ground that could easily cause falls and injuries. 2. ** Dress code ** - Wear comfortable sportswear and take out hard items such as keys and rulers from your pockets. Put your glasses aside to ensure safety. 3. ** Rubberband check ** - Check the rubber band. If there are broken ends, connect them together. ** 2. Group and role confirmation ** 1. ** Group Method ** - The four students could be divided into two groups through the method of "palm and back of hand", or they could voluntarily form a group. 2. ** Decide on the party who puts up the rubber band and jumps the rubber band first ** - Each family would send a representative to decide through the method of "rock, paper, scissors". The winner would jump the rubber band, and the loser would pick the rubber band. ** 3. The process of rubber band jumping ** 1. ** The part where the rubber band is placed ** - Starting from the ankles, followed by the knees, waist, chest, shoulders, ears, head, and finally small and large movements, the difficulty gradually increased. If the party who jumped the rubber band felt that the rubber band was not wide enough at the ankles, neck, and other places, they could ask for it to be widened. 2. ** The way to jump rubber bands ** - The players had to agree on a minimum of four steps. For example, at the beginning, he could stand on either side of the rubber band. In the first step, he jumped into the area surrounded by the rubber band at the same time. In the second step, he jumped up and crossed one rubber band. In the third step, he jumped up again and crossed another rubber band. In the fourth step, he put one of his legs into the rubber band area and jumped up at the same time. ** 4. Game Rules ** 1. ** Action Rules ** - When jumping rubber bands, it was not allowed to touch the rubber band with your hands, otherwise it would be considered a foul. 2. ** Winning and losing rules ** - Single Player Failure Rule: If the player fails to complete all the actions in the specified order, or fails to complete each action in the specified order, the player fails and is eliminated. - The rules of winning and losing in a group: If one member of the group completes the required actions in order, this family can ask the family with the rubber band to upgrade the position of the rubber band, and the family with the rubber band will continue to jump. When they reached the "large-scale" position, they would win completely. 3. ** Game Character Exchange Rules ** - If two members of the same group failed in the process of jumping the rubber band at a certain part, the members of this group would hold the rubber band and the members of the opposite group would jump the rubber band, exchanging roles. In terms of teaching, rubber bands could also be integrated into the curriculum. For example, students could understand the history and cultural background of rubber band jumping through explanation. After the teacher demonstrated the basic skills, the students could try the basic skills such as three-step jump, four-step jump, single-foot jump, etc. Then, they could practice under the guidance of the teacher through the practice method. Finally, they could use the competition method to divide the students into groups to enhance the students 'spirit of cooperation and team awareness. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The second volume of the fourth grade of Hebei Education, the reflection of the teaching of observing objects, is concise
Observing objects from different positions was a necessary foundation for learning space and graphics knowledge. It was helpful to establish the concept of space and cultivate spatial imagination. Students have already started to learn about it in Year 2. This unit will further master the specific methods and techniques to feel the internal relationship between objects and spatial patterns. During teaching, students should be paid attention to fully experience in observation activities. They should use the view to restore the physical link to expand their imagination, and associate the objects that can be placed according to their experience to communicate the connection between the view and the physical object and develop their spatial imagination. Attention should be paid to observation and operation. Students should accumulate perceptual knowledge by using visual teaching aids, learning tools, and observation. They should abstract rational knowledge from them, so that students can have a sense of identity, deepen their impression of the object space, and gradually develop the concept of space. For example, although the introduction of the front, side, and top of the object was easy to accept, the child should be taught to choose the right perspective to observe and fully experience the results of the observation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
