In response to the “Dalian Education Digital Classroom” initiative by the Dalian Education Bureau during the pandemic, our school developed related courses for high school and middle school students during the extended school closure. Since the launch on February 27, the entire school has worked together, with all teachers actively engaged, overcoming numerous difficulties during the pandemic to create micro-courses. In just one month, 39 teachers completed nearly 180 micro-courses. As of April 14, Dalian Tiantu Limited Television has adopted 153 high-quality micro-classes. Starting from March 3, these premium courses have been broadcast daily on Dalian Tiantu Cable Television channels for first and second-year high school and middle school students, and are also available on online platforms such as China Mobile’s “He Education” platform, China Mobile’s “Migu Video”, and China Telecom’s “Internet + Classroom”, allowing for on-demand viewing.
Our school has produced 31 high-quality micro-classes including “Video Switching Techniques”, “Making a Simple Rainwater Alarm”, “Expansion Training: Roman Chariot”, “Sketching the Xinghai Bay Cross-Sea Bridge”, “Creative Making with Hemp Rope”, “Mini Desktop Vacuum Cleaner”, “Making a Handheld Fan”, “Dancing Sound-Controlled Painting”, “Glamorous Transformation of Beverage Bottles”, “Spring-Themed Dress Design”, “Soft Clay Badge Making”, “Chemical Color Bottle Magic”, “Homemade Powered Car”, “Making a Patchwork Drawstring Bag”, “Plant Dyeing with Onion Skins”, “Chemical Printing of Images and Cultural Shirts”, “Handmade Soap Making”, “Identification of Human ABO Blood Types”, “Rubber Stamp Illustration”, “Homemade Water Well”, “Expansion Training: Powered Rocket”, “Clever Repair of LED Lights”, “Storm Bottle”, “Golden Rain in a Bottle”, “Woodcut Printmaking”, “Revealing Fingerprints”, “Preparation and Application of Nutrient Solution”, “Making Essential Oil Hand Cream”, “Solar-Powered Car”, “Soilless Cucumber Seedling Cultivation”, and “Magical Smart Creative Light”, which have been adopted by the Learning Power platform.
Today, we present a micro-class by Teacher Lu Yan on the production of a Foldable Desktop Storage Box. Are you still troubled by a messy desktop? At this time, you need a storage box to help you solve the problem. A storage box, as the name suggests, is a box for storing items, which can concentrate many objects, saving space and making it easy to find. The foldable desktop storage box utilizes the instability of a parallelogram to achieve a telescopic function, maximizing space savings and improving utilization. Today, we will use the most common ice cream sticks and small scraps of cloth in our daily lives to make a foldable desktop storage box.

Topic | Production of a Foldable Desktop Storage Box
Author | Lu Yan Teacher of Robotics Production
Principle Introduction
To give an object telescopic functionality, we need to utilize the principle of the instability of a parallelogram.
Materials and Tools
Ruler, small scraps of cloth, ice cream sticks, compass, pencil, awl, scissors, cardboard, and glue gun. ▼
Punching Ice Cream Sticks
Prepare8ice cream sticks, and punch holes in the center and both ends.
Cross-Fixing the Center Points of Ice Cream Sticks
The punched ice cream sticks are crossed in pairs, and a short bamboo skewer is passed through, with small round pieces fixing both ends.
Assembling the Telescopic Structure
4 pairs of crossed ice cream sticks are connected and fixed with long bamboo skewers to form the basic structure of the storage box.
Confirming the Size of the Storage Box
Measure the length, width, and height of the storage box to determine the size of the fabric needed.Note to leave2centimeters for seam allowance when cutting.
Cutting Fabric and Sewing the Fabric Bag
Cut the fabric according to the measured dimensions and sew it into a bag, making sure to leave space for the bamboo skewer to pass through.
Combining Structures
Combine the fabric bag with the basic structure, with the upper long bamboo skewer passing through the fabric bag and fixed with small round pieces.
Conclusion:This is the method for making a foldable desktop storage box. In real life, many objects are made using the instability of a parallelogram, such as telescopic doors, retractable clothes drying racks, and lifting platforms. Small principles can have great applications, and we should learn to view the things around us with wise eyes.
