For this chemistry calculations review worksheet, students solve 33 review problems about titrations, precipitates, pressure and volume of gases, combustion reactions, heat of combustion, molar concentrations and molecular formulas.

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Putty is proof that learning can be fun! Share the wonderful world of polymers with your class through an experiment. Young scientists create their own silly putty, then examine its properties.

Go get the American Dream lifestyle! The 19th lesson in a 22-part series exploring American history shows learners the post-WWII economic boom. Using primary sources, photographs, and cartoons, groups discuss their findings and present...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

In this atom worksheet, high schoolers answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Students will review a semesters worth of material on this final chemistry review. Information ranges from naming isotopes to pH and molarity.

In this atoms activity, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

In this thermochemistry worksheet, students solve a variety of problems including finding heats or reactions, determining specific heats of substances, finding the amount of energy released in a calorimeter determining the final...

Students analyze data taken from proteomic experiments. In this biology lesson plan, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

In this science worksheet, students use a periodic table to complete the first four rows of a chart. Students use the Internet or research books to complete the last column.

For this current events worksheet, students analyze a political cartoon about the nuclear war threat and respond to 3 talking point questions.

Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...

[Free Registration/Login may be required to access all resource tools.] Shows the calculation of mass number.

This is a chart of the elements including the atomic mass, atomic number, symbol, half-life, and more.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be asked to define atomic number, mass number and understand how isotopes differ from one another. They will be able...

[Free Registration/Login may be required to access all resource tools.] Students explain the workings of a mass spectrometer, and describe how this device is used to determine average atomic mass.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

This lesson explains many basic concepts of atomic structure. It starts with atomic mass and number and then works up to more sophisticated information on electron configuration and how each element fits into the Periodic Table.

Tutorial explains isotopes, atomic weight and how isotopes can be detected using mass spectrometry. Examples are given.
