Learners classify compounds as ionic or covalent. In this chemical bonding lesson plan, students experiment with 6 chemical compounds. They test physical properties such as the melting point, the solubility and the electrical...

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Students experiment with solubility and bonding.

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...

Learners observe how substances are held together by bonds. In this physics lesson plan, students demonstrate how a substance is held together by ripping newspapers and stretching marshmallows. Learners complete a data sheet.

Eighth graders identify the three main types of chemical bonds. In this chemistry lesson, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Hate to vacuum, but enjoy using a vacuum pump? Explore a instructional activity that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor...

High schoolers examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students study acids and how they can be measured.  In this acid lesson students distinguish the properties that create strong and weak electrolytes. 

Students explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

Learners practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...
