biology working models including botany and zoology working models
This is a 3D model of an animal cell using a quarter-cut plastic ball to show the inside. Each organelle is placed in its correct position. The nucleus controls the cell, mitochondria generate energy, the ER transports materials, and the Golgi body packages them. The cytoplasm fills the space, and the cell membrane controls what … Read more
The human hand is one of the most important parts of our body. It helps us hold, grab, write, and do many daily tasks. The hand can move in different ways because it has joints, which are places where bones meet. A hinge joint is a type of joint that works like a door – … Read more
Concept Overview: The human heart is one of the most important organs in the body. It is a muscular organ, about the size of a fist, located in the chest slightly towards the left side. The heart works like a pump, sending blood to all parts of the body. The heart has four chambers – … Read more
Introduction The human digestive system is a group of organs that helps the body break down food, absorb nutrients, and remove waste. It starts from the mouth and ends at the anus. In the mouth, food is chewed by teeth and mixed with saliva, which contains enzymes to start breaking down starch. The chewed food … Read more
This is a rotating wheel model showing the seed germination cycle.As we rotate the top wheel, we can see the different stages in the life of a plant — from a seed, to germinating seed, then a seedling, followed by a young plant, and finally a mature plant that produces seeds again. This cycle shows … Read more
This is a working model of the human respiratory system.The plastic bottle represents the chest cavity.The two balloons inside are our lungs, and the straws act as the trachea and bronchi.The balloon at the bottom represents the diaphragm, which plays a key role in breathing. When we pull the bottom balloon (diaphragm) downward using the … Read more
Photosynthesis is the process by which green plants make their own food using sunlight, water, and carbon dioxide. It is one of the most important natural processes on Earth because it provides food and oxygen for all living beings. In photosynthesis, plants take carbon dioxide from the air and water from the soil. The chlorophyll … Read more
This is a Kidney Working Model. The syringe represents the kidney, and the sponge or cotton acts like the nephrons which filter blood. When ‘blood’ (colored water) is pushed through the syringe, the cotton filters it and sends the clean fluid or ‘urine’ into the plastic tray, which represents the bladder. This demonstrates how our … Read more
In this DIY video, learn how to make a Balanced Diet Wheel Working Model using cardboard, color paper, and a rotating pointer. This simple yet educational project helps students understand the different food groups and the importance of a balanced diet in an engaging way. Turn the arrow to any food group and explain the … Read more
What if I told you that a few plastic lenses and a cardboard tube can turn into a device that lets you see things you never imagined? Let’s build a working microscope! For your microscope working model, here’s how you can build it using cardboard, an LED light, a transparent sheet, a cardboard pipe, color … Read more
This model will demonstrate the working of the human heart, focusing on how blood flows through the heart using syringes, paint, cardboard, and aluminum foil. It will show the basic heart structure (atria, ventricles, and valves) and how the pumping action occurs. Materials Required: Cardboard (for heart structure and base)Syringes (for simulating blood flow)Aluminum foil … Read more
सौर ऊर्जा से चलने वाली सिंचाई प्रणाली एक आधुनिक कृषि समाधान है जो फसलों को पानी देने के लिए सूर्य के प्रकाश का उपयोग करती है। इसे पैसे बचाने, पानी के संरक्षण और पर्यावरण की रक्षा के लिए डिज़ाइन किया गया है। यह प्रणाली दूरदराज के क्षेत्रों में किसानों के लिए विशेष रूप से सहायक … Read more
Creating a reflex action working model using serial lights (red and blue), cardboard, and color paper is a fun and educational project. Here’s a step-by-step guide: Materials Required Steps to Make the Model 1. Prepare the Base 2. Design the Layout 3. Install the Serial Lights 4. Add the Switch 5. Wire Connections 6. Label … Read more
A reflex action working model demonstrates the rapid and automatic response of the body to certain stimuli without conscious thought. Reflex actions are controlled by the nervous system, particularly the spinal cord, bypassing the brain to save time during emergencies. This ensures quick reactions, which are crucial for safety and survival. How the Model Works: … Read more
A microscope working model using cardboard, LED light, and a transparent sheet can simulate the basic functioning of a microscope by demonstrating how light is focused through a lens to magnify objects. The model helps explain the principles behind how a microscope magnifies tiny details by using simple materials to mimic the essential components. Key … Read more
