Preface:

In today’s era where more attention is paid to children’s education, scientific enlightenment education has gradually become an important topic in the field of education. More and more teachers and parents are beginning
Focus on developing children's scientific literacy from an early age, enabling them to establish good character and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child time spent together.
To foster good parent-child relationships, the time we spend together with our children is free from phones, iPads, or TVs—only joy, interaction, and communication. This helps cultivate in children the ability to solve problems on their own.
When children encounter difficulties in decision-making abilities, they need to see, experience, and solve them on their own, as parents and teachers also solve problems in the process of doing crafts. It is possible to develop children's abilities this way.
In a child's world, the imagination allows cars to fly in the sky and the sun to be green... Handicraft DIY activities can develop a child’s hands-on skills through use
Different tools allow the child's little hands to get ample exercise. Pencils, paints, scissors, hot melt gun, glue... They dare to try all kinds of tools, and also...
Various skills are developed at this level. By boosting children's confidence during the craft process, we explore all possibilities together, experience multiple failures, but always succeed.
To some extent, it boosted his confidence. Cultivating focus in children: As the child explores various tools and crafts, he is very focused. If there is no external interference
Sorry, he can keep exploring.

Experiment Objective: Through gaming and entertainment, help children learn more scientific knowledge and develop their hands-on skills.

Principle Application: The function of a magnifier is to increase the viewing angle. Simply place the magnifier at an appropriate distance in front of the object, and you can view the enlarged image through the periscope.

Experimental Cognition: Magnifying the image of objects — the primary function of a magnifier

Just place the magnifier at an appropriate distance in front of the object, and you can view the magnified image through the lens. Pay attention to the object.
The body actually wasn't enlarged.

Knowledge Expansion: Focus on the Secondary Function of Firemaking

Under strong light exposure, the focal point of the lens becomes extremely bright, causing the focal area to zoom in or ignite.

Knowledge Extension: 1. The imaging principle of a magnifier: When an object is within the focal length, a convex lens produces a upright, enlarged virtual image.

2. Microscope

①Structure: eyepiece, objective lens
.

② Imaging principle: The objective lens forms an inverted, magnified real image, while the eyepiece acts like a regular magnifying glass, further magnifying the real image into a virtual image.

3. Telescopes

① Knot
Structure: eyepiece, objective lens.

② Imaging principle: The objective lens forms an inverted, reduced real image, while the eyepiece acts like a regular magnifier that enlarges the real image into a virtual image.
