Standard(s)

S8P1. Obtain, evaluate, and communicate information about the structure and properties of matter. e. Develop models (e.g., atomic-level models, including drawings, and computer representations) by analyzing patterns within the periodic table that illustrate the structure, composition, and characteristics of atoms (protons, neutrons, and electrons) and simple molecules. Construct an explanation based on evidence to describe conservation of matter in a chemical reaction including the resulting differences between products and reactants. (Clarification statement: Evidence could include models such as balanced chemical equations.)

Helium balloons! Fun at a party. But do you know one chemical property of helium? Helium is an odorless, colorless gas at room temperature. It is less dense than air. That's why helium balloons float. It is a non-reactive gas, a member of the Noble gas family. Its melting point is -272.2 oC and its boiling point is -268.93 oC.
