Berries...With a Side of DNA? (High School)
Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...
Curated OER
Condensation Polymerization: Preparation of Two Types of Polyesters
College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...
Baylor College
Moving Air
In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...
Cornell University
Polymers: Instant Snow
Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...
Curated OER
What is Temperature?
Students examine how temperature is the measure of the average kinetic energy of the molecules of a substance.
Curated OER
Density
Students, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...
