Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...

Students interpret basic chemical formulas. When class begins, students interpret a "chemical formula" for fruit salad. After they interpret the recipe, students use the same strategies to identify chemical formulas. They evaluate the...

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Students review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

Students practice naming and writing formulas for simple chemicals. After a review of vocabulary, they create ion flash cards and discuss the rules for writing chemical compounds. They practice naming and writing the formulas based on...

The purpose of this lesson involves reviewing nomenclature and molecular formulas as well as introducing naming molecular compounds and identifying acids. The pupils investigate and understand how conservation of energy and matter is...

Eighth graders interpret the chemical symbols and shorthand used for molecules and equations. Through guided practice, 8th graders work to decipher and interpret the symbols for chemical equations. An opportunity for independent...
