Project-Based Learning(Project-Based LearningProject-based learning is a teaching method that designs learning scenarios, which is a problem-oriented approach based on a student-centered education model that is grounded in the real world.Project-Based LearningThe teaching of this subject involves subjects such as mathematics, physics, technology, engineering, and design, etc., so the teaching content is actually a comprehensive curriculum around various problems. This requires students to solve problems through interdisciplinary and cross-field learning.

Students in order to successfully completeProject-Based LearningProjects require the integration of knowledge from various disciplines and life experiences, as well as cooperation with the team to solve various problems.

In this process, the behaviors of inquiry, communication, innovation, and collaboration exhibited by students are beyond the reach of traditional teaching models. It is precisely through these behaviors that the comprehensive quality of students is enhanced in all dimensions.

Experimental Purpose:

The hard-won happiness of today is not easy to come by, and we should cherish and love our home. Do you know the way the ancients built wooden houses? How does the electric light in modern homes work? Then let's get together today to build our own warm home.

Principle Application:

Theoretical Analysis:

Knowledge point 1: Tenon and Mortise Structure: In ancient times, most houses were built using wooden structures. Very few used metal nails for reinforcement. The hardworking and intelligent ancients used the tenon and mortise method to build house frames. The houses were strong and durable. For example, the Forbidden City is built with wooden tenon and mortise structure. It has remained strong for hundreds of years. Many of our model constructions today use the tenon and mortise structure.
Knowledge point 2: LED lights and direct current: In our lives, there are many kinds of light sources that emit light. For example: sunlight, candles, incandescent lamps, neon lights, LED lights, etc. Many neon lights and advertising lights use LED lights. The LED lights we use today are driven by direct current power. All power supplies that distinguish the polarity are direct current power supplies. The 220V household power and 380V industrial power in our lives belong to alternating current power. They do not distinguish the polarity. The LED light beads have two leads, one long and one short. The long lead is connected to the positive pole. The positive pole is generally represented by a red line. The short lead is connected to the negative pole. The negative pole is generally represented by a black line. If the connection is reversed, the LED light beads will not light up. The LED light beads with tungsten filaments will easily burn out if the connection is reversed.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision of teachers and parents to ensure safety! Do not consume any of the products! They are not suitable for children under three years of age. Do not approach fire sources. Before assembling any batteries, please check if the circuit is clear, all parts of the circuit are complete, and all contacts are good. The + on the battery is the positive pole, and - is the negative pole. Be careful during the assembly process, and if glue is used, do not get it in your eyes or on your skin.
