day and night working model 3D for science exhibition simple and easy innovative howtofunda

Earth rotation working model, in this course teaches students how to create a 3D model that demonstrates how the Earth rotates on its axis, causing day and night. Through hands-on learning, students explore key astronomical concepts like rotation, revolution, and the Earth’s tilt. The course guides learners in building a functional model using materials such as a globe, bulb (to represent the Sun), wires, and a motor to simulate the Earth’s spinning motion. By observing the model, students understand how sunlight falls on different parts of the Earth and how time zones are formed. The course also explains the difference between rotation and revolution and their effects on seasons and day length. Ideal for science fairs and school projects, this course combines creativity and science, helping students visualize complex Earth movements in a simple and engaging way while promoting curiosity about space and planetary science. howtofunda
