Up and atom! After labeling the parts of an atom, young chemists answer 16 diagram-based questions that deal with protons, neutrons, electrons, and atomic number.

This PowerPoint provides a complete recap of all the information needed for a unit on elements and the periodic table. The seventy slides cover the basic notation of elements, energy levels and ionization energies. The trends in the...

Students investigate the periodic table, the structure of the atom and the subatomic particles. In this periodic table lesson plan, students complete 5 activities in order to better understand atoms and the periodic table. They use...

Colored boxes with white font present the basic periodic table of elements to your young chemists. All of the basics are included: chemical name, symbol, atomic number, atomic mass, and the number of electrons in each orbital. A brief...

In this chemistry instructional activity, students complete an adopt an element information sheet. Then they create an advertisement for their element including the information listed. Students also write its important uses, interesting...

In this atomic structure worksheet, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and what the...

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Time to put the knowledge to the test! Young scholars take what they know about the periodic table and build their own from scratch. Using clues from 26 different elements, they place elements in a blank periodic table. The clues include...

Bring a historic chemistry experiment to life in your classroom! Introduce pupils to Thompson's ground-breaking discovery of the electron through a cathode ray simulation. The resource allows users to study the behavior of both electrons...

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...

Student teams use a digital camcorder and iMovie to create a commercial about an element. They also use the Internet and their textbook to gather the following information about their element: the name, the symbol, the atomic number, the...

In this making molecules worksheet, students complete a table of elements with their symbol, atomic number, atomic mass, number of protons, number of electrons, period and group. Students then make models using pipe cleaners and beads of...

In this periodic trends worksheet, students solve ten problems related to elements in the periodic table. Students write electron configurations for atoms and they compare elements and their periodic trends.

In this atom worksheet, students review the subatomic particles, the scientists associated with the atomic theory, and the periodic table. This worksheet has 15 matching, 24 fill in the blank, and 11 short answer questions.

In this history of the atom instructional activity, students answer questions about Thomson's cathode ray apparatus, Rutherford's gold foil experiment and Dalton's beliefs about the atom. Students identify the number of protons, neutrons...

Learners investigate how to determine the percent composition of a mineral in an ore. For this mining an ore lesson plan, students use chocolate chips cookies to represent an ore and they remove precious minerals (the chocolate chips)...

Students investigate the Periodic Table of Elements. In this chemistry lesson, students use a post of the Periodic Table to identify the mass number, atomic number, and atomic symbol. Students create a Podcast to "advertise" a specific...

In this Bohr atom worksheet, students complete a table with the number of electrons of the element, the electron configuration, the mass number, the number of protons, the number of neutrons, the element, the symbol and the isotope...

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

In this moles worksheet, students read about mass, formula mass and moles. They calculate the masses of given numbers of moles of compounds and they calculate the number of moles of given masses of compounds.

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

On this physics handout, pupils read about the Hadron Collider used to make new sub-atomic particles by accelerating protons. They solve 6 math problems that include translating electron volts to Joules. This is geared toward high school...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...
