Could you hold planet Earth in your hands? Of course not — it is way too giant to pick up!
Instead, you can hold a classroom globe to see all the oceans and continents in one glance.
How does a little ball help us understand our huge planet?
What Is a Model?
In science, a model is a copy or picture that stands for something in the real world.
📊A side-by-side comparison diagram on a clean white card. Left side shows the massive Real Earth in space with stars, labeled 'Real Earth: Huge and far away!'. Right side shows a child holding a tabletop globe, labeled 'Globe Model: Small and easy to study!'. An arrow connects Real Earth to the Globe with the label 'A model stands in for the real thing'. Cute flat vector illustrations, soft blue (#22b7ff) accents, rounded corners.
Models are helpful when the real object is too big, too tiny, or too dangerous to explore directly.
Are all models just smaller versions of big objects?
Types of Models
Models can be smaller like a toy rocket, or made extra big like an enlarged model of a tiny bug.
Models can also be a simpler drawing or visual diagram that leaves out messy details so you can focus on the main parts.
📊Three side-by-side colorful cards showing three ways models work. Card 1 (Smaller): A toy airplane model representing a giant jet plane. Card 2 (Bigger): A giant plastic ladybug model to show tiny antennas clearly. Card 3 (Simpler Drawing): A clean 2D sketch of a flower showing roots, stem, and petal with arrows. Bright friendly icons, child-friendly typography, cards have soft borders (#e6e6e6) and clear labels: 'Made Smaller', 'Made Bigger', 'Simpler Drawing'.
Do you need special factory plastic to build a science model?
