The following is a lesson plan for making a small creative invention: * * 1. Teaching objectives ** 1. Let the students understand the basic structure and principles of the ship, and cultivate their scientific cognitive ability. 2. To stimulate the students 'creativity and hands-on ability to make small ships through small inventions. 3. Cultivate the students 'teamwork spirit and learn to communicate and cooperate in the production process. * * 2. Teaching preparation ** 1. [Materials: Abandoned plastic bottles (as the main body of the ship), ice cream sticks, rubber bands, small motor (with propeller), battery box, batteries, wires, scissors, glue, plastic sheets, colored pens, etc.] 2. [Location: Spacious classroom or hand-made workshop.] * * 3. Teaching process ** #(1) Introduction (10 minutes) 1. By playing videos of ships sailing on the sea or showing pictures of ships, students could arouse their interest in ships. Ask the students about the purpose of the ship and why the ship can sail on the water. Guide the students to think about the structural characteristics of the ship. 2. He briefly introduced the invention he was going to make today--making a small ship. #(2) Knowledge Explanation (15 minutes) 1. Explain the basic structure of a ship, including the hull, power system (such as engine, propeller, etc.), rudder, etc., so that students can understand the functions of each part. 2. It introduced the materials used to make the small ship and how these materials simulated the real structure of the ship. For example, a plastic bottle could be used as a hull because it could float on water. A small motor and a propeller formed a power system, just like the engine of a real ship that drove the propeller to move the ship forward. #(3) Production (30 minutes) 1. hull construction - The students were instructed to clean the discarded plastic bottles and use scissors to make simple modifications to the plastic bottles. For example, they could cut out some small windows on both sides of the bottle, which could be used as viewing windows or ventilation holes for ships. - The students were asked to draw their favorite patterns on the plastic bottles to decorate the ship. 2. Power system installation - Help the students fix the small motor at the end of the plastic bottle. You can use glue or plastic sheets to make a simple stand to fix the motor. - Connecting the battery box and the motor, connecting the positive and negative poles of the battery box to the positive and negative poles of the motor with wires, and then putting the battery into the battery box. - The propeller was installed on the shaft of the motor to ensure that the propeller could rotate flexibly. 3. Production of other parts - The rudder of the ship was made of ice cream sticks and fixed to the rear of the ship. The direction of the ship could be controlled by adjusting the direction of the rudder. - He could use the remaining materials to make some small decorations, such as the flag on the ship. #(4) Testing and improvement (15 minutes) 1. Put the small ship into the water (it can be a water tank or a small pool) to test if the small ship can sail normally. Observe the state of the small ship in the water, such as whether it is traveling in a straight line, whether the power is sufficient, and so on. 2. If there was a problem with the small ship, the students were guided to analyze the problem. For example, if the ship did not move forward, it might be a motor connection problem or the propeller was stuck by a foreign object; if the ship's direction was unstable, it might be the installation position or angle of the rudder. Then, he encouraged the students to improve the small ship. #(5) Exhibition and Communication (10 minutes) 1. Ask the students to show the small ship they made and introduce their creativity, problems, and solutions during the production process. 2. Students were organized to visit each other's works, and they were encouraged to learn from other works and make suggestions for improvement. * * 4. Reflection on Teaching ** 1. the key of success - During the teaching process, most of the students showed a high enthusiasm for the creative invention of the small ship and were able to actively participate in every production process. This showed that the way of learning through practical operations could effectively stimulate the students 'interest in learning. - The students displayed a certain creativity in the production process, such as the hull decoration, the design of the rudder, etc. They had their own unique ideas, which helped to cultivate the students 'innovative thinking. - Teamwork spirit had been trained to a certain extent. During the production process, students helped each other, exchanged ideas, and solved problems together. 2. deficiencies in - For some students with weaker hands-on ability, there were certain difficulties in the production process, such as the installation of the motor, the connection of the wires, and other relatively delicate operations. In the future, more individual guidance was needed for these students. - In terms of material preparation, although they tried their best to consider the variety and maneuverability of the materials, some students still asked for more different types of materials to enrich their works. In the future, they could collect more types of waste materials in advance for students to choose from. - In terms of time allocation, the production segment was slightly tight, resulting in some students not having enough time to adjust their works to the best state during the testing and improvement segments. Next time, he could extend the production time or simplify the explanation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
