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...

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...

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.

For this molecules worksheet, students review the parts of an atom and use element mass to determine isotopes. Students give the group, period, and classification for the given elements. This worksheet has 6 short answer questions and 17...

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...

For this moles worksheet, students read about mole and learn how to calculate the number of moles in specific mass of compounds. This worksheet has 14 problems to solve.

In this Dalton worksheet, students read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

In this nuclear decay learning exercise, high schoolers read about alpha and beta decay and the isotopes formed by the reactions. Students solve nine problems including writing the equations for the decay of radioactive isotopes,...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

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).

Here is a straightforward practice test for first year chemistry learners. Responders balance equations, identify types of reactions, represent electron configurations, and solve stoichiometry problems. Keep this handy to use as...

For this periodic table worksheet, students complete a chart with the appropriate element symbol, the atomic mass and the atomic number. They classify elements by their groups and as metals, nonmetals or semi-metals. They also answer two...

In this stoichiometry worksheet, students review definitions and equations associated with molarity, density, atomic mass, molarity, and dilutions. This worksheet has 18 word problems.

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

In this periodic table worksheet, students answers 10 fill in the blank questions by reading information form a periodic table. Then also complete Bohr Models of the atoms of 12 different elements.

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

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

Chemistry classes will appreciate this color-coded, single-page reference sheet for The Standard Model of particle physics. It is divided into two main sections: elementary particles and compound particles, both with their antiparticles....
