Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Students illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Learners explore how an oil spill is contained and cleaned up. They investigate an oil absorbing polymer that is hydrophobic, absorbs up to 19 times its own weight in nonpolar liquids, floats on water, and can be reused or disposed of by...

Students investigate issues of degradation and weathering of polymeric materials during their useful life. They evaluate photodegradable plastics and their viability as an environmental solution for litter and investigate the qualitative...

In this chemistry worksheet, students are offered a variety of assistance to help them be successful in organic chemistry. They will have access to the library, missed class notes and computer interactive programs to help them with...

In this chemistry worksheet, learners examine the periodic table and how it is used in the context of interpreting compounds and their structure.

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

Twelfth graders perform dihybrid crosses and calculate phenotype and genotype ratios. In this series of science lessons, 12th graders explain the process of anodizing aluminum. They research on the benefits and harm caused by resonance...

Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...

Students investigate temperature using the TI. In this chemistry instructional activity, students analyze the change in temperature, as chemicals are dissolved in water. They analyze data collected using the CBL 2.

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

Young chemists learns about acids and bases by coming up with a solution that will test for each. They also access the Internet to perform research. They are encouraged to contact students in other schools by conducting the experiment at...

What is it that makes Mentos candy and cola such an explosive combination? Find out through scientific inquiry and experimentation. This presentation walks learners through the scientific process and allows them to speculate whether it...

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

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

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 investigate the linear dimension change of heated plastic film and relate the results to processing and service use of the materials. They calculate percent change in dimension as related to anisotropy and molecular reorientation.

Students 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.

Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...
