Curated OER
Dimming the Sun
Students collect, interpret and analyze weather variable data. They describe atmospheric variables that affect evaporation. Students create graphs and analyze the information collected.
Curated OER
Fallout!
High schoolers plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall....

Middle School Chemistry: Lesson Plans: Why Does Water Dissolve Salt?
Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.

Middle School Chemistry: Lesson Plans: Temperature Changes in Dissolving
Media-rich lesson in which learners discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...
