1, ready to use materials and tools.
2. Align the bottoms of the two cups.
3. Wrap it in paper glue twice.
Experimental principle:
This is because the Magnus effect is used, when the cup rotates, the air velocity on the upper and lower sides will be different, resulting in different forces. For a cylinder that rotates clockwise when flying to the left, the lateral force is upward, so children must operate clockwise if they want to make the plane fly.
What's the use of learning handicrafts?
First, children's growing interest.
Children like activities such as cutting and pasting. In this process, they can experience the fun of hand-making, effectively combine various art media, learn and explore new things, perfectly integrate the knowledge learned from various disciplines, and realize the connection between art and study and life.
Second, the handicraft class is to develop the brain and exercise the children's practical ability.
On the surface, handicraft class is students' practical ability, but in fact it is the development of brain function. The brain provides good ideas in manual activities and completes the production of works through the coordination of hands and brains. It exercises the flexibility and accuracy of the hand and promotes the development of the brain.
Third, the sense of accomplishment and satisfaction when completing handmade works.
Children have a desire to show off in front of adults. When they finish a beautiful work, they will take the initiative to show off in front of you in order to get praise from adults. This is the psychological characteristic of children in childhood. The completion of each child's handmade works is an affirmation of himself. Handmade works should pay attention to the student-centered learning style and guide students to actively explore the methods of classroom production in order to complete the production of exquisite works.
Fourth, handcraft is a combination of handcraft and painting, which can meet the needs of children in many aspects.
Handmade is not limited to pasting or splicing materials, but should be combined with painting, and the two should be perfectly integrated to promote the connection between disciplines. Painting can better decorate handmade products, help to enhance the expressive force of works and meet the various learning needs of students. So as to promote the development of students' imagination and better reflect the student-centered classroom creation model.
