1, making a maze box:

Make a small maze box with cardboard, colored paper and scissors. Children can design and build their own maze, and then use balls or other objects to navigate in the maze.

2, making solar cars:

Use solar panels, small engines and waste to help children make solar cars. They can learn the basic principles of solar energy and electric motors and experience the application of science and technology for themselves.

3, making a simple circuit board:

Use conductive paper, wires and small light bulbs to help children make a simple circuit board. They can learn the basic knowledge of current and circuit and try to build a simple circuit by themselves.

4. Make a simple robot:

Use waste materials, small motors and battery boxes to help children make a simple robot. They can learn the basic knowledge of robots and experience the fun of making robots themselves.

5, making three-dimensional printed building model:

Use 3D design software or network platform to help children design and print their own 3D building models. They can learn the basic knowledge of computer aided design and 3D printing technology.

6, making electromagnet:

Use copper wire, batteries and nails to help children make a simple electromagnet. They can learn the basic principles of electromagnetism and electromagnetic induction and try to make an electromagnet that can attract metal objects.

These technological handicraft projects can help children develop their practical ability, scientific thinking and creativity. At the same time, it can also stimulate their interest in science and technology, engineering and other fields. When carrying out these projects, please ensure the safety of children and make appropriate adjustments according to their age and ability.

Extended data:

Small-scale scientific and technological production is characterized by high scientific and technological content, simple structure, easy to find and process materials, low cost and independent completion. It is especially suitable for students and can cultivate their creativity, thinking ability and practical ability. Teachers can appropriately inspire students to create high-quality small works.

Small-scale scientific and technological production can be divided into imitation and creation. Imitation is mainly formed by imitating others, and most children's science and technology small productions begin with imitation. From the beginning of imitation, you gradually become interested, and you can create your own.

Creative means that this kind of small production is mainly created by children themselves. Like building your own car or something. There are different levels of creation. Generally speaking, children's scientific and technological production is primary, and we can't ask too much.
