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...
Curated OER
Heating/Cooling Curve
In this heating and cooling curve activity, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the substance and the...

Murder in the First Degree - The Death of Mr. Spud
Secondary learners investigate exponential functions in a real-world scenario. They collect data on the temperature of a cooling baked potato, enter the data into lists, and graph the data using a scatter plot before finding an...
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.

States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to boil water through...
Curated OER
Ice Ain't Easy
Students are introduced to the laws of thermodynamics. The 1st law of thermodynamics states that the energy must be conserved when two objects of different temperatures come in contact. If one object gains energy, the other object must...

More Thermochemistry Problems
This two-page assignment covers basic thermochemistry concepts. Chemistry learners identify exothermic and endothermic processes, explain a phase change graph, and draw an energy level diagram. There are no problems to solve, just...
Curated OER
Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry lesson plan, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.
Curated OER
Ice Ain't Easy
Students are told that objects in contact with one another reach an equilibrium temperature. A hot object placed in a cool liquid always cool off. It never happens that the object gets hotter and cool liquid gets colder. Students predict...

Calculator-Based Lessons Help Examine Real-World Data
Students may determine equations based on graphs and regression models.
Curated OER
Celsius to Fahrenheit
Students convert degrees between two different units. In this algebra instructional activity, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.
Curated OER
Aerodynamics
Learners discover the basic principles of aerodynamics, including the roles and identity of natural forces involved. They examine how the force of gravity is overcome by the curved shape of an airplane wing and air pressure.
