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

Third graders sort and classify the four Arthropod classes. They are given puzzle pieces of one Arthropod example. Each group is to put their puzzle together, glue it on a piece of construction paper and label the ir puzzle.

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

In this proton NMR spectrum learning exercise, students indicate the number of signals in the proton NMR spectrum for compounds and give the structure of the compound and assign the NMR peaks based on given data. This learning exercise...

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

Create adorable penguin-themed books and manipulatives with this cool resource. Instructions for use are provided, as are the stars of the show: five warmly dressed penguins who decide to go for a dip.

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...

Practice naming ternary compounds with this PowerPoint presentation. Individual slides show the patterns for memorizing the nomenclature for polyatomic ions. Several examples are included for student practice. This thorough and...

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....

In this science worksheet, young scholars examine the graph with elements in order to differentiate atomic mass and categorizing the content.
