In this ions activity, students complete a table by combining the given ions in different combinations to make a neutrally charged chemical compound.

In this catalysts instructional activity, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

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 view an illustration of the Hudson River watershed and identify the bodies of water shown. They discuss what happens when fresh and salt water mix. Students view a teacher demonstration of the stratification of fresh and salt...

In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...
