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.

Objective of the experiment: To enable students to have a preliminary understanding of the principles of the balance, to teach students how to make and use a balance themselves, and to cultivate their practical ability.

The principle of application: In actual balance scales, they operate based on the principle of levers. There is a pivot point in the middle of the balance beam, and each end has a
A measuring dish is used, with objects and weights placed on it (normally with the object on the left and the weights on the right). If the lever is balanced, the masses on both sides are equal.
When the quality is unequal, add or subtract the magnetic code in the right pan accordingly. And adjust the position of the dial on the scale until the beam returns to its original position.
Balance, when the mass of the object equals the total mass of the magnetic weights on the right plate plus the scale value corresponding to the upper weight.

Experimental Cognition: This material is a teaching manual model designed to help students understand the working principle of the balance scale, allowing for a rough comparison of lighter and smaller objects.
The weight of the body has no practical measurement significance, as various reasons such as processing technology, the balance of the scale may not be guaranteed after installation.
Therefore, the two sides have added adjustable sliders to balance the scale, which can be fitted on both sides, or one side, or not used at all.
The specific adjustment will depend on the situation.

Knowledge Expansion: Balances are divided into: 1. Ultra-micro electronic balance: The large weighing capacity of an ultra-micro balance is 2 to 5g, with a scale resolution less than one millionth of the large weighing capacity. 2. Micro balance: The weighing capacity of a micro balance is generally between 3 and 50g, with a scale resolution less than one ten-thousandth of the large weighing capacity. 3. Semi-micro balance: The weighing capacity of a semi-micro balance is generally between 20 and 100g, with a scale resolution less than one ten-thousandth of the large weighing capacity. 4. Constant electronic balance: This type of balance has a large weighing capacity generally between 100 and 200g, with a scale resolution less than one ten-thousandth of the large weighing capacity. 5. Analytical balance: It is actually an electronic analytical balance, which is a general term for constant, semi-micro, micro, and ultra-micro balances. 6. Precision electronic balance: This type of electronic balance is a general term for electronic balances with an accuracy level of Class II.

Knowledge Extension: Students can find their own materials to make a unique scale.
