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...

Learners 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 differentiate the two types of remote controllers namely RF and IR. In this technology lesson, students test their properties using CEENBoT and Isobot. They present their findings in class.

Students experiment with one method of detecting infrared radiation. They simulate the detection of infrared radiation using a liquid crystal sheet.

Students investigate the law of reflection by using mirrors. In this physics lesson, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

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

Students are able to define and give an example of a proportional tax and the impact that it can have on different income groups and explain how a proportional tax takes the same percentage from all tax groups.

High schoolers 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...

What is an urban heat island? Middle school meteorologists find out by comparing temperatures at different locations on campus. They relate their findings to what might be happening in a concrete jungle and how it impacts local weather....

There's more to light than ROYGBIV! An enlightening laboratory investigation has learners explore the world of infrared light. When they use goggles that take away visible light, they experience how things look with only infrared light.

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...

Learners 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...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

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....

Where does all the heat go when the sun goes down? An interesting lesson has learners explore this question by monitoring the infrared radiation emitted over time. They learn that hot spots cool more quickly that cooler spots.

Pupils 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 analyze spectrums as related to forensics. In this chemistry lesson, students define spectroscopy and discuss its use in chemistry. They discuss how the Forensic Paint Chip is used to help solve crimes.

Students investigate the urban heat island effect. In this urban heat island effect lesson, students learn how trees, grass, asphalt, and other things on the school grounds effect temperature. They use the information to generalize it to...

Eighth graders are introduced to concepts related to the Solar System. In groups, they participate in an experiment in which they must describe a ray of light and how it travels. They draw a diagram of the electromagnetic spectrum and...

Young scholars explore electrical resistance through various experiments. In this physics lesson, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a resistor.

Middle schoolers observe how measurements are made with different instruments.  In this remote sensing lesson students investigate the physical state of surfaces including the surfaces of the solar system. 

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