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...

Ozone, made of three bonded oxygen atoms, is found 15-30 km above Earth, has a strong smell, is blue, and blocks sunlight from hitting the surface of Earth. The 22nd lesson in a series of 36 specifically focuses on the important elements...

Fourth graders examine matter and the periodic table of elements. In this matter lesson plan, 4th graders discuss atoms and their composition. Students explore the periodic table of elements and use it to spell words out of the elements.

In this chemistry worksheet, students use the Internet to research the elements in the Periodic Table to locate the number of proton, neutrons, and electrons. They also draw pictures that illustrate one or more uses for their elements.

In this atoms worksheet, students use their periodic table to determine how to draw the 20 atoms given in this graphic organizer.

In this atomic structure worksheet, students use the periodic table to complete a chart for 11 elements/ions in terms of atomic number, number of protons, neutrons and electrons.

Young scholars investigate the periodic properties of elements in the periodic table. For this periodic properties lesson plan, students experiment with elements from the Alkaline Earth Metals, the Halogens, the Transition Metals, and...

In this atoms worksheet, students calculate the formula mass for chemical compounds. This worksheet has 12 problems to solve.

Students find the average atomic mass of M & M's.  In this chemistry lesson, students are given a sample of the element chocolatium and the atomic mass of each sample.  They then find the average atomic mass.

Students study the concept of periodic motion and relate it to the movement of a pendulum. They discover that the period of a pendulum is dependent on the length of the pendulum and independent of the bob and the amplitude.

Learners experiment to determine the period of a pendulum. In this periodic motion instructional activity, students use different pendulums to determine their periods. They use various amplitudes to determine its effects on the period.

Written for an introductory organic and biochemistry course, this exam will challenge your class. They label functional groups and stereocenters on drawings of molecules, draw structures given the name, complete drawings of chemical...
