Overview
The Molecule Polarity PhET Lab is an interactive simulation designed to help students understand the concept of polarity in molecules. In this lab, students are able to explore the behavior of different molecules and determine their polarity based on the arrangement of the atoms and the distribution of electron density.
The lab begins with an introduction to the concept of polarity and its importance in determining the physical and chemical properties of molecules. Students are then able to manipulate the atoms and bonds in different molecules to observe how changes in structure affect molecular polarity.
The simulation provides students with a visual representation of the electron distribution within molecules, allowing them to see how the arrangement of atoms and their associated electronegativities can result in a molecule being polar or nonpolar. Students can also measure the dipole moment of different molecules to further understand the relationship between molecular structure and polarity.
The Molecule Polarity PhET Lab is a valuable tool for teaching students about the concept of polarity and its impact on molecular behavior. By allowing students to interact with the simulation and analyze different molecules, they are able to develop a deeper understanding of the factors that contribute to molecular polarity.
Background
In this lab, we will explore the concept of molecule polarity using the PhET interactive simulation. Molecules can be either polar or nonpolar depending on the distribution of charge within them. This distribution is determined by the arrangement of atoms and the electronegativity difference between them.
Electronegativity is a measure of an atom’s ability to attract electron density towards itself in a covalent bond. When atoms in a molecule have different electronegativities, a partial positive and a partial negative charge are created on the atoms, resulting in a polar molecule. If the electronegativity difference between the atoms is small or zero, the molecule is nonpolar.
In this lab, we will investigate the factors that determine the polarity of molecules. We will explore how the shape and symmetry of a molecule affect its polarity, as well as the role of electronegativity. We will use the PhET simulation to visualize and manipulate different molecules, and observe the resulting changes in polarity.

Results
In this lab, we observed the polarity of various molecules using the Molecule Polarity PhET simulation. We used the simulation to investigate the properties of different molecules and determine whether they were polar or nonpolar.
By manipulating the atoms and bonds in the simulation, we were able to see how the shape and distribution of charge in a molecule affect its polarity. We found that molecules with an uneven distribution of charge, or a polar bond, were considered polar, while molecules with an even distribution of charge, or a nonpolar bond, were considered nonpolar.
During the lab, we discovered that molecular shape plays a significant role in determining whether a molecule is polar or nonpolar. For example, molecules with a symmetrical shape, such as methane (CH4), were nonpolar, while molecules with an asymmetrical shape, such as water (H2O), were polar.
Additionally, electronegativity also influenced the polarity of a molecule. If the difference in electronegativity between the atoms in a bond was significant, the bond would be polar, resulting in a polar molecule. For example, in the case of hydrogen chloride (HCl), the electronegativity difference between hydrogen and chlorine caused the molecule to be polar.
In conclusion, the Molecule Polarity PhET lab provided a hands-on way to explore the concept of molecular polarity. It allowed us to visualize and manipulate different molecules, understand how their shape and electronegativity contribute to their polarity, and ultimately determine whether they are polar or nonpolar. This lab served as a valuable tool in reinforcing our understanding of the topic and allowed us to apply our knowledge in a practical and interactive manner.
