Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good personalities and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate the ability of children to solve problems by themselves. When children encounter problems, they should first see and experience the solution themselves, because parents and teachers solve problems in the process of doing crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green. Playing with DIY crafts can cultivate children's practical ability by using different tools, which fully exercises children's little hands. Brushes, paints, scissors, hot-melt guns, glue"Children are brave to try any tools and to some extent, they are developing different skills. Improving children's self-confidence in the process of handcrafts, we try everything possible together, experience many failures, but we always succeed, which to some extent enhances their self-confidence. Cultivating children's concentration when children explore various tools and handcrafts, they are very focused, and if there is no external disturbance, they can continue to explore.

The purpose of the experiment: Children assemble their own educational toys, which can stimulate their innate desire for exploration and growth. It establishes a learning environment and creates a space for activities and exploration, helping children to maximize their potential. The right choice can create opportunities for learning for children, and its impact will last throughout their lives. When parents play with their children and provide appropriate guidance, they can help children complete the process of understanding knowledge, establishing relationships, recognizing rules, self-reliance, and establishing self-awareness during the fun of play.

Principle Application: Light from an object after passing through a camera lens is converged on the film, forming an inverted, reduced, real image.

Experimental cognition: The lens of a camera is equivalent to a convex lens.

Knowledge Expansion: Concave lenses are made based on the principle of light refraction. Concave lenses have a thicker center and thinner edges. Concave lenses are divided into double-concave, flat-concave, and concave (or positive crescent shape) forms. Concave lenses have the role of converging light, so they are also known as converging lenses. Thicker concave lenses have the functions of distant vision and convergence, which is related to the thickness of the lens. Presbyopia glasses are concave lenses.

Knowledge Extension: When a convex lens is placed in the sun, the light will focus into a single point; under a fluorescent lamp, the light again focuses into the shape of the lamp; when looking out the window, what changes does the light experience? Yes! Adjust the distance of the object to form an image, and you can see the scenery outside the window formed near the focal length.
