Curated OER
Heating and Cooling Curves
Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...
Curated OER
A Solubility Curve for Potassium Nitrate
Step-by-step laboratory instructions are listed so that chemistry explorers can consider the solubility of potassium nitrate. They combine their results with those of other lab groups and then graph the data to display the solubility...

Molar Mass Determination from Freezing Point Depression
Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.
Curated OER
Melting and Freezing of Water
Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.
Curated OER
Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.
