Lesson Objectives...
Gather and communicate information from a scientific text adapted for classroom use to determine the central ideas of Dalton’s atomic theory with regard to the patterns in the particulate structure of matter that makes up all substances.
Construct an explanation using models of the molecular structures of different substances to predict which gas must be produced (effect) in the bath bomb reaction based on the types of atoms that make up the substances (patterns), and use it to explain what is happening to the particles (matter) in the system to cause the production of this new substance.
Molecules are made of atoms and all the substances in our world are made of very few types of atoms.
The same substance is made of the same type of molecules (or atoms throughout). The number, type, and arrangement of atoms in the molecules that make up a substance are unique to that substance.
In a chemical reaction, the particles that make up old substances can be broken apart and the atoms that make them up can be rearranged to form new molecules to make new substances.
