Curated OER
Teaching about Increased Conductivity: Are Culverts The Culprits?
High schoolers encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.
Curated OER
Antacid Lesson Plan
Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...
Curated OER
Phosphate Testing Contract
Students examine how to prepare an experimental procedure. In this scientific method lesson students conduct an investigation on phosphate.
Curated OER
Serial Dilution of CuSO4 and Changing the Value of Paint
Students relate solution concentration and saturation to color and compare methods of changing value and color intensity with paint solutions.
Curated OER
Determination of the percentage of Acetic Acid in Vinegar
Students determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...
Curated OER
Spectrophotometry Lab
Students use a machine called a spectrophotometer to determine how much light is absorbed by certain substances. Students record the absorbance and the % of light transmitted for different color solutions, graph their results, and then...
Curated OER
A Self Directed Inquiry into the Identification of Unknowns
Students gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.
