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...

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...

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

Although this lesson is directed at a chemistry class, all laboratory classes require the use of metric measurement. Here is a half-hour video introduction to measurement systems and a thorough teaching about the base-ten metric system...

Do not pass this resource by! Everything you need to teach the property of density,and the separation of mixtures is here: an educational video, several classroom handouts, and a laboratory exercise. The video is engaging, though a...

"The name is Bond. James Bond." Or is that "Chemical Bond?" Assign the viewing of the video as homework, and then have your chemists come to class to practice drawing electron dot diagrams and Lewis structures with the several bonus...

Explore thermal energy with this short episode. Jiggling molecules and hand-drawn animation help to explain that just because something has a lot of thermal energy, it doesn't necessarily feel hot to the touch. This is an ideal addition...

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Scientists discover over 15,000 new species each year. Despite studying life on our planet for all of human history, we still don't know how many species exist on Earth. An informative video from a biology playlist presents the dilemma,...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Explore the validity of a famous quote by Carl Sagan, "We are made of star stuff." An episode of the ACS Reactions playlist explains how deteriorating stars became the origin of all the elements in our world. Learners consider different...

The goal of this science instructional activity is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Connect the dots and assist young chemists as they demonstrate covalent and ionic bonding. Class members use their knowledge of valence electrons to predict compound formulas as they arrange electrons into various bonding structures...

Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

To guide learners through observations of chemical samples in the lab, this resource asks them to give all formulas and complete the attached data sheet.  There are multiple questions about categories of elements and general...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the activity. In conjunction with the research students make inquiry of the...
