The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...
Curated OER
Oil Embargo!
Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...

Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
Flame Test
Students conduct a flame test on different substances. In this chemistry lesson plan, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.

Chemical Bonding
Eighth graders identify the three main types of chemical bonds. In this chemistry lesson plan, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.
