How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of experiments, pupils...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

How attractive is your intermolecular forces lesson plan? Draw your class in with an activity that includes research, presentation, and demonstrations. Chemistry scholars work together to create claims about the each intermolecular...

Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

How does hydrogen bonding explain ice crystals? An engaging interactive answers just that. Scholars explore how polar molecules interact and observe the changes as temperature fluctuates as well as the hydrogen bond attraction.

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. 

Chemists love London (dispersion forces)! Presentation begins with an explanation of intermolecular forces including hydrogen bonding, dipole-dipole attraction, and London dispersion forces. It also covers polarity and the relative...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to mixing and...

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms in an equation,...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity....

A very neat instructional activity has been produced by Pearson Education, Inc. for use in a general chemistry class. The first nine questions are fill in the blanks for a paragraph about types of bonds and electronegativity. Five...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Even though the questions on this activity pertain to general chemistry, it was created for an AP biology course. It is crucial for biology learners to grasp these concepts as a foundation for biochemical processes that they will...

What's the solution to gaining insight into your class' progress? Give this brief quiz a try! Part 10 of a 14-installment series on states of matter tests learners' skills in the areas of dilution and the properties of water, including...

Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Students investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...

In this bonding worksheet, students read about the types of bonds that hold compounds together. They are given fifteen common materials and they identify the types of bonds that hold each together.
