So the mean is not always the best center? By working through this exploratory activity, the class comes to realize that depending upon the shape of a distribution, different centers should be chosen. Learners continue to explore...

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...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

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

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

A chemistry lesson presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this instructional activity: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium...

Raise the curtain to a class play that depicts the Civil War through both factual information and literary devices. The performance showcases the Battle of Antietam (Battle of Sharpsburg) and brings attention to women's roles,...

Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

While many chemicals are used in biology class, many pupils don't understand the material safety data sheets. The lesson explains each part and the importance of understanding the forms. Young scientists use safety equipment to ensure...

Avoiding lab safety rules will not give you super powers. The lesson plan opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and...

Class members research citizenship in Ancient Rome and in the United States and use the provided graphic organizers to compare the rights and responsibilities of citizens in these two democracies.

Why are some immigrant groups in the United States embraced while others become disenfranchised? To answer this question, teams investigate why groups emigrated to the US, why some of these these peoples were...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Building upon previous knowledge of sequences, collaborative pairs analyze sequences to determine the type and to make predictions of future terms. The exercises build through arithmetic and geometric sequences before introducing...

How does propaganda influence our vote? Through grand conversation, scholars gain information about what is and how to identify the different ways propaganda is used in a presidential election. Using their new-found knowledge, citizens...

Introduce your class to nanotechnology applications with three demonstrations that showcase scientific principles related to ferrofluids, quantum dots, and gold nanoparticles. Groups will work more closely with these applications in the...

It may be time to get to know the skeletons in your family. The first instructional activity in a series of 5, introduces the class to the concept of osteoporosis. The class members brainstorm possible causes and whether the family...

It is best to know all about the skeletons in the closet. The third segment in a five-part series focuses on bone structure, development and growth, and functions. Class members connect what they learn to their study of...
