Here's something unusual and thoughtful: have your scholars do some pensive reflection themselves before tackling how such meditative techniques are used in prison rehabilitation programs. They watch the...

Technology—changing lives and transforming war. Your tech-loving historians examine photographs and primary documents to explore how technology changed not only World War I, but also how it moved society forward. They apply their...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

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...

If your class's knowledge of the Ice Age is limited to animated movies, use this lesson plan to strengthen their knowledge. After sharing what they know about the Ice Age, young readers explore a news article seeking to dispel...

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

Watt is going on here? Middle schoolers are learning about energy use and carbon dioxide emissions! In the first part of this lesson, learners measure how much energy different appliances consume and calculate the amount per day. In...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Insolubility and density? Yup, it's art class, of course. To create insoluble paintings that continually move and change, kids mix water-based paint with mineral oil and seal the mixture in laminating pouches.

Imagine having to give up cell phones, computers, and TV? What would be lost? What gained? An examination of the Drokpa, a nomadic people who live in the grasslands of Tibet, provides class members an opportunity to consider how access...

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a instructional activity that stresses the importance of controlling all variables. The...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on the entire year's curriculum when they take this 13-page test.

Students complete a unit to evaluate their impact on the environment and greenhouse gas emissions. They conduct Internet research, develop a list of their electrical and energy use, calculate their share of greenhouse gases, and identify...

Students investigate how natural hazards can present personal and societal challenges as well as the cost involved. They assess the risk analysis considerations with global warming and their impacts on an ecosystem. An estimate of the...

Second graders investigate the effect of melting glaciers to sea level. For this earth science lesson, 2nd graders simulate the process in the lab by conducting an experiment using ice cubes and clay. They explain the consequences of...

For this thermodynamics worksheet, students describe the reactions given and then determine the thermodynamic calculations. This worksheet has 14 problems to solve.

In this climate change instructional activity, students read through the sentences and answer the questions that survey them about their knowledge of climate change.

Learners discuss the definitions of physical and chemical properties and changes. They vaporize a solution of salt and water, observing the sodium chloride that is left behind.
