What is a small technology project?

The characteristics of small technology projects are characterized by a "small" word. Where is the "small"? （1）Simple structure. Generally, as long as a few parts are made and assembled, it is ready. （2）Easy to find materials. Many materials can be found at home, such as empty cardboard boxes, toothpaste tubes, foam plastics, tin cans, wasted ballpoint pen cores, broken toys, iron wires, iron sheets, etc. （3）Easy processing. Most projects have low technical requirements for craft skills, which can be mastered by primary school students. （4）Low cost. Some projects can even be done for free, without increasing family burdens. （5）Quick results. Many projects can be completed in half a day, which meets the psychological needs of children and is easy to popularize. 2 Activity forms （1）Open science courses to make science education universal and guide students to make. （2）Establish interest groups to guide students to make. （3）Encourage students to choose their own topics and independently complete small projects, and give appropriate guidance when necessary.Activity content and tutoring methods: (1) Produce according to the drawings, instructions, or printed materials. (2) Focusing on the development of creativity and intelligence, this is a small-scale technology project. It mainly involves creating toys that children enjoy, with the following forms: ① Teachers introduce a method for making a small project and the scientific principles behind it, using actual objects to demonstrate, which sparks students' interest. Students then innovate and create based on these principles. For example, the "Chicken Feeding" is a pull toy that uses the principle of levers. When pulling, the movement of the chicken heads is consistent or opposite, which is due to the different positions of the lever's force point and support point. After understanding the principles, students have designed and created many novel lever pull toys, such as "I'm Sitting on a Rocket to Space," "Fishing for Cats," "Playing Table Tennis," "Crossing the Canyon," etc. ② Transforming waste into treasure technology projects. Teachers explain how to use the gears from old clocks and toys to design and create new toys. Some students were inspired to complete innovative and high-quality activity toys on their own, such as hand-operated electric dry boats, electric bump cars, robots, clown dancing, owls and mice, etc. ③ Special topic technology project competition. Different topics are set for students of different grades, and everyone in each class designs and makes their own projects. The class selects a team, and then competes in the grade-level competition. For example, a wind-powered car race was held for students in grades 4, 5, and 6. We stipulated that the wheels of the cars must be made from thick paper and cannot use ready-made wheels or other substitutes. Other sizes, weights, and styles are not limited. Another time, a rubber band-powered car race was held, with only the uniform specification and length of rubber bands being limited. This way, students' enthusiasm was very high, and the designed and made racing cars were diverse, fully demonstrating their intelligence and creativity.Attention: (1) Separate grades according to age, knowledge level, practical ability, and interests and choose different content for making. For students in lower grades, choose content that is easy to succeed, such as small parachutes; for students in middle and higher grades, the difficulty should be increased. (2) Encourage innovation. (3) Emphasize safety during the making process.
