Students explore ionic bonding. They draw examples of ionic bonding and explain the activities of the electrons of the elements. Students use paper plates and candy to draw electron configurations of given atoms.

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...

Students 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...

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

High schoolers experiment with solubility and bonding.

Don't take for granted the technology behind power packs. Build an understanding of the chemical mechanics of a battery pack that charges your phone. The simulation allows young scientists to manipulate the type of elements in a pack and...

Students conduct a simple conductivity meter to test the ionic or non-ionic nature of water samples including one from their home.

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.

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

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

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson 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 pressure and...

Students investigate the properties of matter. In this properties of matter instructional activity, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown...

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.

Students 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 describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

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...

Students develop an understanding of the concept of matter. They l participate actively in the bubble raft experiment as described on the Center for Thermal Spray Research's website. They demonstrate dislocations and grain...

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...

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...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

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...

Pupils participate in an Electron Square Dance in which they act the part of atoms. They follow the structure of different atoms suggested by the teacher.
