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,...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use. 

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

It's like a periodic table variety show! When the plethora of periodic table apps becomes ho-hum, this one may revive interest.

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 plan 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...

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...

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

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...

Students 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.

Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

Fourth graders examine matter and the periodic table of elements. In this matter lesson, 4th graders discuss atoms and their composition. Students explore the periodic table of elements and use it to spell words out of the elements.

Students observe the periodic table and draw the Lewis Dot Diagram.  For this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

Ninth graders examine the Periodic Table. In this element instructional activity, 9th graders observe the chemical reactivity of elements. They graph the properties and discuss the trend in the group and period of elements. The students...

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 investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

High schoolers record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Students identify the different periodic trends. In this chemistry instructional activity, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

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.

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.

Communicate chemistry clearly with a concise guide to writing chemical equations. It covers everything from the parts of a chemical equation to the different types of reactions that budding chemists may encounter.

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...
