Molecular models are like tiny toy models of different molecules. They are made to look like the real molecules and are helpful for scientists to understand the structure and behavior of molecules. They have pieces that represent atoms and bonds. The atoms can be of different shapes and colors, and the bonds can be straight or curved. By changing the pieces and the way they are connected, scientists can create models of different molecules. Molecules are very important in our everyday lives, and understanding them is important for science. Molecular models help make that easier to understand.
