In this alchemy worksheet, learners read about how alchemists kept their experiment notes in secret code. Students design their own secret code for the given elements. This worksheet has 2 problems to solve.

Students explain how Daniell cells work. In this electrochemistry lesson, students conduct a variety of experiments to explore the different types of cells. They create a model of Daniell cell.

Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

Students undertake a series of experiments related to the water cycle. All experiments use John Dewey's experiential philosophy as their bases. Each lesson plan is clearly based on philosophy and attempts to be relevant.

For this chemistry worksheet, high schoolers fill in 10 blanks with the appropriate term, they determine if 4 statements are true or false, they match 6 terms with their definitions and they answer 3 questions. Topics include areas of...

Students gather and analyze scientific data from a local creek. Over weeks or months, students observe their local environment, collect water samples, and evaluate test results. Extension activities are suggested for evaluating...

In this translating learning exercise, students translate sentences in English to the International Phonetic Alphabet. Students translate 10 sentences.

In this comprehension quiz #1 worksheet, students interactively complete 8 sentences based on the story given with immediate online feedback.

Students examine the different careers associated with chemistry and see how it is used everyday.  For this forensic lesson students research a chemistry related career and write a presentation to give to the class.

In this resources learning exercise, learners compare and contrast physical and chemical properties and changes. Students review the periodic table, pattern of atomic numbers and chemical reactivity. This learning exercise has 56 short...

Students simulate the development of smog. They discover how it forms naturally in nature. They read news articles about the ozone and pollution. They discuss what they can do to lower the pollution they generate.

Chemist Paul Lauterbur pioneered the use of nuclear magnetic resonance (NMR) for medical imaging. He developed a technique, now known as magnetic resonance imaging (MRI), in the early 1970s that involves the introduction of gradients in...

Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different...

As a chemist, you will learn to deal with complex mixtures of many compounds. In this interactive activity, you will learn the basis of separations using acid-base extraction. In the virtual lab you will simulate an actual experiment and...

Svante Arrhenius was born in Vik, Sweden, and became the first native of that country to win the Nobel Prize. The award for chemistry was bestowed to him in honor of his theory of electrolytic dissociation. Arrhenius also developed the...

Humphry Davy was a pioneer in the field of electrochemistry who used electrolysis to isolate many elements from the compounds in which they occur naturally. Electrolysis is the process by which an electrolyte is altered or decomposed via...

This is a fantastic biography of Rosalind Franklin. It has links to both additional information and images to help illustrate the biography.

Peter Debye carried out pioneering studies of molecular dipole moments, formulated theories of magnetic cooling and of electrolytic dissociation, and developed an X-ray diffraction technique for use with powdered, rather than...

Theodore William Richards (1868-1928) was considered the foremost experimental chemist of his time. He won the Nobel prize for his role in determine the atomic weights of many elements. This house was built in 1900 with design input from...
