Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

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. 

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

An educational presentation includes atoms, molecules, the four major elements, as well as neutrons and protons. Additionally, slides focus on atomic number, mass number, atomic weight, polar and nonpolar covalent bonding, ionic...

Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

An in-depth lesson, the fourth activity in a series of 36, begins with teaching how the periodic table's arrangement came to its current design. Using this knowledge, pupils then move on to analyze the arrangement of elements to their...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...
