Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic of exploration in the field of education. More and more teachers and parents are beginning to
Emphasizing the cultivation of scientific literacy in children from an early age, so that children develop good personalities and behavioral habits from the very beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, and change
Good parent-child relationships, the time we spend with our children without smartphones, iPads, or television is filled with joy, interaction, and communication. It can help cultivate the ability to solve problems on their own.
Decision-making skills are important for children to learn. They should first see and experience the problem themselves to solve it, because this is how parents, teachers, and others solve problems in the process of doing crafts. This can help develop children's problem-solving skills.
The imagination of children, in their world, cars can fly in the sky and the sun can be green... Playing with DIY crafts can cultivate children's ability to practice by using "
Different tools were used, allowing the child's small hands to fully engage in activities. Brushes, paints, scissors, hot glue guns, glue....., they were all willing to try out, and to a certain extent, they were also able to master them.
Degree of development of different skills. Improving children's self-confidence in the process of handcraft, we try all possibilities together, experience many failures, but always succeed, in a
To a certain extent, it has enhanced his self-confidence. When a child is exploring various tools and crafts, he is very focused, and if there is no external interference, he will continue to be so.
Excuse me, he can keep exploring.

The purpose of the experiment: To enable children to learn more about scientific knowledge and their own ability to practice by means of game entertainment.

Principle Application: The function of a magnifying glass is to amplify the field of view, and by placing the magnifying glass at a suitable distance in front of the object, one can view the enlarged image within the monocular.

Experimental Cognition: Amplifying the Image of Objects - The Main Function of a Magnifying Glass

Place the magnifying glass at an appropriate distance from the object to view the enlarged image through the lens, and pay attention to the object.
The body has not actually been magnified.

Knowledge Expansion: Focusing on the Secondary Function of Ignition

Under strong light, the focal point of the lens will be particularly bright, and the focal point will become focused or ignited.

Knowledge Extension: 1. The imaging principle of a magnifying glass: Objects within the focal length of the convex lens form a upright and enlarged virtual image.

2. Microscope

① Structure: eyepiece, objective lens
。

Imaging Principle: The object lens forms an inverted, magnified real image, and the eyepiece functions like a regular magnifying glass, magnifying the real image into a virtual one.

3、Telescope

①结
Construct: eyepiece, objective lens.

Imaging Principle: The object lens forms an inverted, reduced real image, and the eyepiece functions like a regular magnifying glass, amplifying the real image into a virtual one.
