In this moon's atmosphere worksheet, learners read about the tenuous lunar atmosphere and solve 4 problems. They find the density of helium particles, they find the grams of given atoms in the moon's atmosphere and they find the volume...

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 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.

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

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...

High schoolers 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.

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

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.

For this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

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.

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.

[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.
