Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Name is Bond, covalent bond. Through readings and answering questions, classes explore the different types of chemical bonds, their characteristics, valence shell electron pair repulsion theory, and atomic orbitals. 

Cookies and chemical equations have a lot in common! Using cookies as a reference, scholars learn to balance chemical equations. Pieces of the cookies represent different parts of the compounds and elements. This is the sixth installment...

The 20th installment in a series of 36 focuses on the characteristics of the p-block elements. Learners discuss, read about, and answer questions pertaining to the occurrence of these elements in nature, their electron configurations,...

Ozone, made of three bonded oxygen atoms, is found 15-30 km above Earth, has a strong smell, is blue, and blocks sunlight from hitting the surface of Earth. The 22nd lesson in a series of 36 specifically focuses on the important elements...

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...

Substances with the same empirical and molecular formula must be differentiated by their structural formula. Part two in a series of 36 has pupils using chemical formulas to calculate how much of a compound is present in a given...

Cyanide, a coordination compound, is used in the extraction of gold and silver. Part 24 in the series of 36 delves into the world of coordination compounds. Classes learn, through readings, discussions, and answering questions, how to...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...
