Development of a Model: Analyzing Elemental Abundance
How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...
Curated OER
Order, Order All Electrons
Students read the periodic table and apply their knowledge of the construction of atoms. They demonstrate reading the electron configuration of an element on the periodic file.
Curated OER
Electronegativity
Students identify the type of bonding between two atoms of elements given their electronegativity values. They study the trend of electronegativity across the periodic table in small groups.
Curated OER
Isotopes of Pennies
High schoolers demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.
Curated OER
Structure of the Atom
Learners practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.
