Sodium Hydroxide Lesson Plans

Young scholars experiment with cubes of agar and sodium hydroxide and discover that the smallest cube has the largest surface area to volume ratio (SA:VOL).

Students participate in a simulation of how diseases are transmitted. Each student holds a test tube, with only one containing the "disease" while the others have water. They move around the room until told to stop. Using droppers to place some of their solution into their neighbor's tube, they are spreading the disease. Finally, they try to determine the original source of the infection.

Students brainstorm different information they know about the AIDS virus and how it is spread. They use sodium hydroxide and phenolphthalein to simulate how quickly the AIDS virus is spread.

Eleventh graders work with a variety of solutions to determine which combinations will create a precipitate when mixed with another. They complete a chart with their predictions and results. When students finish the lab, they discuss the results and their successes and failures in predicting the precipitates.

Students explain the Chatelier's Principle. In this pH lesson, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.

Seventh graders investigate acids and bases. In this acids and bases lesson, 7th graders use household items such as coffee, lemons and soap to define acids and bases. They observe a demonstration to show how indicators determine if a solution is an acid or a base. They observe red and blue litmus paper tests and they conclude the lesson by testing common household substances with litmus paper to determine if they are acids or bases.

Students see how an infectious disease such as AIDS may be quickly transmitted throughout a population. They conduct a simulated transmission of an infectious disease and mathematically determine the number of possible infected individuals.

Students investigate energy involved for bonds to form and break. In this thermodynamics lesson plan, students experiment with chemical reactions to observe endothermic and exothermic reactions, they explore entropy and the effects of its increase in a reaction and they calculate the free energy of a reaction.

Students observe demonstrations to show the solubility of gases in liquids. In this gases instructional activity, students discover the relationship between temperature and pressure to and how they affect the solubility of gases in liquids. Students investigate an ammonium fountain demonstration an interpret the phenomenon.

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of fusio
