Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Students discuss the difference between atoms and elements. They analyze how compounds are formed. Students discuss the difference between covalent bonds, hydrogen bonds, and ionic bonds. They review bonding with diagrams, "Atoms or...

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of...

Students experiment with solubility and bonding.

Students experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

Students create a polymer using Borax and Elmer's Glue. In this chemistry lesson, students identify monomers made of hydrocarbons and then brainstorm a list of polymers and their uses.

High schoolers work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Eighth graders identify the three main types of chemical bonds. In this chemistry instructional activity, 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 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 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...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

The purpose of this lesson plan involves reviewing nomenclature and molecular formulas as well as introducing naming molecular compounds and identifying acids. The students investigate and understand how conservation of energy and matter...

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

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

High schoolers examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual...

In this matter worksheet, students calculate volume and partial pressure for gases, compare liquid and vapor phases, and review the characteristics properties of gases. This worksheet has 12 multiple choice and 3 problems to solve.

Students 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...

Young scholars investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

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...

In this kinetic theory worksheet, students answer questions about kinetic energy, they calculate volumes of gases at STP, they answer questions about temperature and they convert from one unit of temperature to another.

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...
