Students investigate weather-related phenomena including the cause of rain, evaporation, snow, and wind. Students also explore how a coat helps us stay warm in the cold and how blocking the sun to make a shadow causes the temperature to decrease. Lesson 1.1 – What Makes it Rain? Students use tiny drops of water on a…

NOTE: Those these are indicated for 5th grade, they align with both 5th grade and 8th grade AzSS standards. Through exploring melting, dissolving, and chemical change, students discover that mass is conserved during all these processes. Lesson 4.1 – Conservation of Mass Students measure the mass of substances before and after melting, dissolving, and a…

NOTE: Those these are indicated for 5th grade, they best align with 8th grade AzSS standards. Students investigate the solubility, density, and other properties of solids and liquids to identify substances based on their unique characteristics. Lesson 2.1 – Using Dissolving to Identify Substances Students compare the dissolving of salt and sugar and then conduct…
