Inter-State Matters

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...

In this elements and bonding instructional activity, high schoolers classify given elements, they identify valence electrons in atoms, they explain the reactivity of elements, and they explain why certain atoms gain electrons while...

Students explain how the elements are arranged in the periodic table. For this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they chose.

In his previous videos, Sal showed students how to calculate how much energy is needed to change various amounts of water from state to state when the atmospheric pressure is constant. In this video, he shows students how to use phase...

Need help reading those phase diagrams given in chemistry class? This video module provides a good review of how to read the diagrams which show the different states of matter and when they transition to another state according to...

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments...

Don't get mixed up about the differences between elements, mixtures, and compounds! Part one of a six-part series discussing these important classifications of substances illustrates simple tests one can perform to determine a material's...

Young scholars identify and describe transition metals. They discuss alloys and their benefits. Students research one common, alloy, its composition, properties, and uses. They are asked for some common properties of most transition...

There are three basic states of matter: Solid, liquid, and gas. Help your learners with visual impairments to understand the chemical nature of each state of matter with tactile elements. Marbles are used to model the particles in each...

Student teams use a digital camcorder and iMovie to create a commercial about an element. They also use the Internet and their textbook to gather the following information about their element: the name, the symbol, the atomic number, the...
