Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

Young scholars explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

This organic chemistry lab activity is appropriate for teaching polymerization, percent yield, melting point, or the types and uses of polymer materials. Chemistry pupils imagine that they are working for a company to develop a special...

Students are introduced to how the differences in solubility of materials are used in the manufacture of fibers and films. They are also introduced to the various processes used to make films and fibers. Pupils prepare fibers using wet...

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Students treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

Students determine that the relative concentration of copper ions in water can be determined by a color comparison. They make a copper (II) sulfate solution of a given concentration. Students dilute their initial solutions until their...

Students are introduced to a gas chromatography using a discovery-based approach. They are presented with a scenario/industrial application where their job is to verify that the company's mouthwash contains a specific percentage of...

Students recover latent prints by iodine fuming, cyanoacrylate fuming, and dusting with powder, after a lecture/discussion on fingerprinting techniques. They each provide a fingerprint for identification by another student. A database of...

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

Conduct a written literary discussion and diminish stress about public writing. Class members, already arranged into literature circles, compose and post responses to novels, signing with initials or class number. The process continues...

Eighth graders consider cross-curricular connections between social studies, singing, and current events. They listen to the song, "I Can't Cry Hard Enough." view scenes from September 11, then create presentations using images, a...

Sixth graders investigate the livability of different planets in the universe by researching and organizing information from a number of sources in this unit project. They decide on a location for a space station which they support in an...

By creating an energy brochure, teams of science learners inform others about the advantages of using alternative energy sources. An instructions page for your class and a grading rubric are provided. The lesson focuses on photovoltaics,...

Here is a fun resource that your kids will love. While reading the book Because of Winn-Dixie, they analyze the story's main characters by creating an online scrapbook. The purpose is to have them identify character traits and use...

First graders explore the theme of dental health and hygeine. They make tooth loss predictions, count lost teeth, and graph tooth loss. In addition, they listen to dental health stories, read online stories, create spreadsheets, and play...

Learners create a scrapbook of college student life during the 1960's using digital archives and Internet research. They read and discuss the article "What's the Matter With College?" and then compare college experience of today with...

Write it. Read it. Find it. That's the name of the game here! Elementary learners trace basic words, say them aloud, and find the matching picture. All words on this worksheet end with the letter g. 

Young learners will build confidence with this illustrated activity. For each question, they determine whether the word starts or ends with sh. An example given is the word fish. Does it begin or end with the sh sound? 

Young math learners work with subtraction on the number line. Each of the ten questions provides the problem in its numerical form and contains a number line to illustrate the problem. Even if learners don't need the number line to...

In this rational equation worksheet, learners solve 20 equations with a variable in the denominator of one more terms. They also read real-life application problems, write a rational equation to fit the problem and solve the equation....

First graders discover the parts of a plant. In this science lesson, 1st graders identify and label the parts of a plant and record their findings on a word processor.
