6.2: Matter & Energy 3 Dimensions & Progressions

Unit 3

STANDARD 6.2.1

6.2.1 Develop models t o show that molecules are made of different kinds, proportions, and quantities of atoms . Emphasize understanding that there are differences between atoms and molecules, and that certain combinations of atoms form specifc molecules. Examples of simple molecules could include water (H2O), atmospheric oxygen (O2), and carbon dioxide (CO2). MS-PS1-1

CONCEPTS

SKILLS

● Combinations of atoms form molecules ● Difference between atoms & molecules ● Examples of simple molecules

● Develop Models ● Understand ● Provide examples

LEARNING PROGRESSIONS

● Everything is made of matter ● Atoms are the smallest form of matter ● Atoms are too small to see ● Model of atom ● Atoms combine together to form molecules ● Model of Molecule ● When molecules combine they react differently VOCABULARY ● Atom ● Nucleus ● Matter ● Element ● Molecule ● Protons Neutrons

● Electrons ● Compound

POSSIBLE PHENOMENA

● Salt and sugar look and feel similar; however, they do not taste similar. ● Washing a cut with water does not hurt as much as washing a cut with hydrogen peroxide. ● Pure sodium explodes in water. But when it combines to form a molecule with Chlorine, it becomes Sodium Chloride (table salt), something safe for us to eat.

END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS

● I can develop a model identify components of individual atoms and molecules. ○ Nouns (electron, proton, neutron, nucleus) ○ Expanded Nouns (positive charge, negative charge, neutral charge, electron cloud, etc.) ○ Diagram or model with labels
