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.

Have you ever experienced the feeling of being on the brink of a bottomless abyss at a science museum or a youth palace? Is it really a bottomless abyss? Then today, let's get our hands dirty and uncover the mysteries behind it.

Experimental Purpose:

Knowledge point 1: Planar mirror: Do you know why you can see yourself when you look in the mirror? Because a planar mirror reflects the light from the object back. When it reflects to your eyes, you see the object in the mirror and yourself.
Knowledge point 2: Semi-transparent lens: A semi-transparent lens is a special mirror processed through a special technique. It can reflect light from some objects back, and some light can pass through the lens. You can see the items on the back of the semi-transparent lens. It can be seen through under certain conditions, and it cannot be seen through under certain conditions.
Knowledge point 3: Semi-transparency and reflection: The middle light strip serves as the scenery, with a flat mirror in front and a semi-transparent lens near the eye. Light that hits the semi-transparent lens reflects and transmits part of it. The light will reflect back and forth between the flat mirror and the semi-transparent lens. Every time the light reflects off the semi-transparent lens, it will form an image on it. The more times the light reflects off the semi-transparent lens, the more images will appear on it. Each time the light reflects off the semi-transprt lens, some of it will pass through. Therefore, the effect of the tunnel will gradually diminish.
Knowledge point 4: Direct and parallel circuit connections: When the positive and negative poles of the power supply line are connected to the positive and negative poles of the light line, it is a direct connection circuit. When the positive and negative poles of multiple light beads are connected to the corresponding poles of the circuit, it is a parallel circuit. If one light bead breaks, the others will continue to shine. In contrast, in a series circuit, when one light bead breaks, all the light beads will stop shining.

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.
