Degradation and Weathering of Polymeric Materials
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...
Curated OER
Hand Lotion Analysis
Students prepare a sample of a commercial hand lotion for analysis by HPLC to determine the percent composition of two common cosmetic preservatives, methylparaben and propylparaben. They perform the analysis and the data is evaluated to...
Curated OER
Playing With Science
Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...
Curated OER
Creating Biodiesel and Mitigating Waste
Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...
Curated OER
Grow an Alum Crystal
What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and water. You may...
Beyond Benign
Stoichiometry Challenge
Have you been searching for environmentally friendly chemistry experiments to use in your high school laboratory? This stoichiometry experiment replaces a conventional aluminum to alum lab by using sodium carbonate and calcium chloride...
Curated OER
# 05 Color Me Analytical
High schoolers are introduced to colorimeter on two levels. They investigate how to physically manipulate the colorimeters. Secondly, the students start on a pathway of discovery to one of the most important principles in analytical...
Curated OER
Addition Polymerization: Preparation of Polystyrene Using Two Types of Initiators
Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Wet Etching in Nanofabrication
Chemistry and physics combine forces to benefit nanofabrications. Learners examine the process of wet etching in nanofabrication. Using corrosive substances such as lemon juice and Coca-Cola, they model the etching process. They then...
Curated OER
Determination of Phosphorus Content in River Water
Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...
Curated OER
Chemical Resistance and Synthetic Polymers
Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.
Curated OER
Condensation Polymerization: Preparation of Nylon 6/6
Students participate in a lab activity in which they synthesize nylon 6/6, calculate the percent yield by mass, identify the polymer as thermoplastic or thermoset, and determine the melting point, density and end-product use of the polymer.
Curated OER
Elastomers: The Best Bungee Cord
Students examine elastomeric polymers in a lab activity in which they design a bungee cord. Students must determine the tensile strength, percent elongation, and plot stress versus strain graphs for their experiments on rubber bands...
