Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Get out the goggles and conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects. Young chemists observe and describe the harmful...

Ninth graders examine how the U. S. was aided by the Allies in World War II before the U. S. declared war. They analyze the evolution of U. S. foreign policy from the beginning of WW II through U. S. Declaration of War

Help your students gain sensitivity and become aware of the implications of the words they see, hear, and use about lesbian, gay, bisexual, and transgender people. After making lists of words or phrases they hear or use in school...

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Examine and distinguish between words that have similar definitions but different connotations. Middle schoolers define connotation and denotation and participate in a "shades of meaning" contest in small groups. Groups use the...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

For this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

Young readers examine the details in an 1821 painting by Jacques-Louis David depicting two sisters who are exiled princesses. They read a tale about the Brothers Grimm, who were writing fairy tales during the same time period that these...

Here is a top-notch handout to supply your chemistry class with. It covers valence electrons, Lewis diagrams, the octet rule, and more! Technically it is less of a worksheet than a detailed explanation of these chemical bonding concepts....

Review the terms denotation, connotation, diction, and mood in paragraph writing. After defining the terms, middle schoolers practice writing examples of both connotation and denotation. They complete a connotation and denotation...

In this interactive Internet  assignment, physical science investigators answer 11 questions about the atom, the subatomic particles, and atomic structure. They can click on "Reveal Answer" to discover if they are correct. They also...

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...

A thoroughly-written lesson plan and a plethora of worksheets about integers comprise this resource. Neophyte number crunchers learn to recognize integers, add and subtract them, and apply the concepts to the designing of a personal...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Here is a thorough exercise in forming hypotheses for scientific investigations. Young scientists consider factors that may be related to the question they would like to address. They think through measurable changes that may result from...

Casting the American Revolution into a bright, informative light, this presentation details many key facts about the strategies and decision during the revolutionary campaigns. The latter half of the slides prompt viewers to examine why...

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Two pages take chemistry learners on a survey of acids and bases. High schoolers write formulas and name compounds. They identify conjugate bases and acids with the aid of a table (not provided). On the second page, two different acids...

Each of these slides presents the basic scientific details and situations where charge, or static may appear. Handouts of the empty PowerPoint slides could be provided so that students could work through these examples and correctly...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...
