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.

Experimental Objective: To understand how saltwater can be transformed into kinetic energy. To exercise students' ability to complete experiments using simple tools and materials. Through these two points, to enhance students' observation and analysis skills.
Analytical and judgmental thinking ability.

Principle Application: This saltwater-powered car model does not require any batteries and can run with just a little saltwater. It can help children understand the knowledge of green energy.
And develop good habits of environmental protection from a young age.
Brine-powered cars are concept vehicles powered by brine, and human attention is once again focused on the rich sea with high salt content!
salt
The principle of a water battery: Magnesium plates and carbon plates react chemically in salt water (the electrolyte). When the magnesium plate loses electrons and the carbon plate gains electrons, an electric current is generated.

Experimental Cognition: First, take a zinc strip from a 5V battery and polish it clean: Take a copper key: Zinc strip and copper key: Prepare a cup of salt water, and use the zinc strip and copper key with the salt water.
The crocodile clamp is clamped in the cup, kids can try it, but be careful with the battery.

Knowledge expansion: The earliest such inventions were used in telegraph machines, providing power sources for telegraph machines.

Knowledge Extension: In 1799, the Italian physicist Volta immersed a zinc plate and a tin plate in saltwater and discovered that an electric current passed through the wire connecting the two metals. Therefore,
He then placed a soaked cloth or paper between many zinc sheets and silver sheets, stacked them flat. When touching both ends with his hands, he felt a strong electric shock. Volta used this
A method successfully produced the world's first battery, the Voltaic battery.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision and guidance of your teacher and parents to ensure safety! All products are prohibited from consumption! They are not suitable for children under the age of three.
For children's use only. Do not approach fire sources. Before assembling the battery, please check if the circuit is unblocked, if the components on the circuit are complete, and if all contacts are in good contact.
Alright, on the battery, the + sign indicates the positive terminal, and the - sign indicates the negative terminal. Be careful during the assembly process, and avoid getting glue on your eyes or skin if you use any.
