Students recognize epoxy glue formation as two part polymerization (usually the curing agents act as co-monomers). They monitor the reaction by the changes in viscosity of the reacting mass, the temperature rise and fall, and the...

Students isolate and determine the amount of plasticizer in polyvinyl chloride. They use Infrared Spectroscopy (IR) or Fourier Transform Infrared Spectroscopy (FTIR) and gravimetric techniques in this experiment.

Students explain the content, purpose, and impact of the Tax Reform Acts of 1969 and 1986.

Students receive an overview of the role and purpose of taxes in American history. They identify different types of taxes implemented by the US government and explain the origin of the federal income tax.

Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the...

Pupils record temperatures at different locations around campus. They examine the results and draw conclusions about how materials and colors affect the amount of heat produced. They also analyze Los Angeles' temperature records over a...

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Take a very basic understanding of circuits and develop a strong understanding of the parts and function of a circuit. This activity is developed to be an independent exploration of circuits from the basics to series and parallel models....

Students evaluate the basic rationale, nature, and consequences fo taxes. They describe why governments need taxes as revenue to provide goods and servicesin this series of activities.

Students study the concept of animal migration with the change of seasons. They discover that migration can be hazardous, and the distance migrated can be short or long.

Students study the concept of electricity, what an electric current is and its relationship between voltage and resistance.In this electrical lesson plan students solve problems using Ohm's law, and research alternative sources of...

Young scholars begin their examination on the conflict in the Middle East. Before beginning, they complete a survey and discuss their answers to hopefully reduce their bias about the region. They examine the problem in the Middle East...
