To create this animation, I began by designing each scene in PowerPoint. For the Earth and Moon visuals, I used PowerPoint’s built-in 3D models. I selected the 3D objects for Earth and Moon from PowerPoint's 3D Model library, inserted them into the slides, and positioned them to represent the orbital layout. Using PowerPoint’s animation settings, I applied a rotation animation to the Moon, making it orbit around the Earth to simulate realistic movement. To illustrate the tidal effect, I used a semi-transparent blue ellipse placed around the Earth. This ellipse represents the areas affected by tides. For the animation, I applied a “Grow/Shrink” effect to simulate the ebb and flow of the tides. I set the growth percentage to slightly expand and contract, creating a pulsing effect that mimics tidal movements.

Additionally, I synchronized the timing of this animation with the Moon’s rotation around Earth. As the Moon moves, the blue ellipse grows and shrinks to represent how the Moon’s gravitational pull causes tidal changes. This synchronized animation gives a more realistic visualization of the tidal effect on Earth’s water.
