Curated OER
The Periodic Table
In this science worksheet, students use a periodic table to complete the first four rows of a chart. Students use the Internet or research books to complete the last column.
Curated OER
Periodic Trends
Students identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Periodic Table Patterns using Fabulous Periodic
Young scholars explain how elements are arranged in the periodic table. In this chemistry instructional activity, students group the eggs according to a certain pattern. They compare this to elements in the periodic...
Curated OER
Build Your Own Atom
Young scholars build a model of an atom using an online program. For this chemistry lesson, students discuss the different parts of the atom. They complete an independent research about their chosen element.
Curated OER
Measuring Vibration of Energy
In this chemistry activity, students measure the different vibration levels of energy. They use the fundamental vibration frequency formula to calculate the Morse potential for a given chemical bond. There are 2 questions.
Curated OER
The Bohr-Rutherford Model of the Atom
In this atom model worksheet, students explore how scientists developed the Bohr-Rutherford atom model. Students complete 15 fill in the blank statements.
Curated OER
Causal Patterns in Density Phenomena
Students realize that density exists. They develop a mental model of density-to realize that something is going on that they cannot see to account for differences between materials.
