Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and water. You may...

Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

What a cute approach to chemical bonding! Atoms all have human names and are attending at a dance. Who will pair up with whom? By reading the characteristics, and not the element name, chemistry whizzes figure out the bonding pairs....

Nitrogen is an essential element for productive farming. An interactive lesson explores the chemical makeup of different fertilizers and their corresponding nitrogen content. The interactive challenges individuals to complete molecular...

How do the different types of soil allow water to flow? Scholars compare flocculated and dispersed soils and their ability to move water through the soil. Silt, sand, and clay particles clump together and create large pores in the soil...

Does your class understand how things become charged? Are you positive? Before negative grades emerge, assign a fun interactive! The first in the five-part Static Electricity series contains three levels of charge-related questions and...

The anode, the positive electrode, attracts negative charges, which is why we call negatively charged atoms anions. The interactive allows pupils to match six different anions to the associated properties when testing. Offering four...

Sometimes playing games in class isn't a bad thing. Science sleuths evaluate and calculate pH and pOH with an online resource. They then manipulate concentration information and relate it during a series of puzzles.

Feeling a little neutral about your pH and pOH teaching strategy? Perk it up with engaging puzzles! Young scientists relate ion concentration to pH and pOH, as well as the dissociation constant for water. The resource is available as an...

Naming complexes can be, well, pretty complex! Simplify a study of ligands using interactive puzzles. Junior chemists match up the name, formula, and complex name, then solve a series of logic games with the information.

Young chemists love it when colorful solid products appear in a reaction vessel! Scholars discover the products that form during halide ion tests through a hands-on activity. Users go online and apply chemistry knowledge and reasoning...

Scientists call ions with a negative charge anions. Scholars work through one matching puzzle and four logic puzzles reviewing the chemical formulas for anion ions. Each level increases in difficulty and solidifies the concept in pupils'...

We are family! Why are elements in the same group so similar in many ways? Science scholars explore the relationship between valence electrons and an element's characteristics through a video from the JFR Science playlist. The narrator...

It's true! Opposites do attract! A straightforward video lesson explains the basics of ionic bonding. Using visual models, the instructor describes the repeating patterns in an ionic compound. She also explains how a formula unit simply...

Explore the process of writing and naming ionic formulas and compounds. Pupils learn to build ionic compounds by analyzing their charges. The instructor then explains how to name the newly created compound.

Investigate the ions of the atomic world. By referencing the periodic table, the video instructor describes the different charges of monoatomic ions and references both their stock and classical names. She then defines polyatomic ions...

I asked the cat sitting next to me if he had any Sodium Hypobromite; he said NaBrO. The third video in the six-part series introduces how to name polyatomic ions such as Sodium Hypobromite. It offers the general rules and a few example...

Add a charge to your classes with a lesson on ions! The video instructor describes the formation of ions through an analysis of the electron configuration. Scholars learn the configuration and the notation related to ions.

So, what's the big deal about plasma? Part two of a 14-part series of videos about solids, liquids, and gases helps scholars gain understanding of this important fourth state of matter. The video describes how a gas becomes plasma, how...

Polyatomic ions... where do I begin? One of the most difficult concepts for budding scientists to learn and recognize comes to life in an enlightening resource. Show pupils some demonstrations, via the sixth video in a series of 10, to...

Here's a presentation that answers the age-old question of the covalent bond to the ionic bond, "Why won't you share?" Included is information about covalent and ionic bonds, the octet rule, ionic compounds, cations versus anions, and...
