Bold boxes present parts of the periodic table, with some of the contents conveniently missing. Beginning chemists fill in the blanks, which may include the atomic number, atomic mass, atomic symbol, or element name. Beneath each box...

Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...

A model is worth a thousand words. Young scholars use what they know about the structure of hydrocarbons to build Lewis dot structures and molecular models. Their tasks include multiple bonds, geometric hybrids, and various isomers.

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Twenty-six elements, compounds, and ions are randomly listed for chemistry whizzes to analyze. They are to diagram the Lewis electron dot structure for each, resulting in further insight on the configuration of different molecules. They...

The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for a...

As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required...

Learners are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

In this alkanes worksheet, students complete a table with the chemical formula, the structural formula and the condensed formula of various alkanes given different numbers of carbon atoms. They answer three questions about valence...

In this electron configuration worksheet, students write the electron configurations of 22 elements and compare their valence electron configurations. They list the elements that are similar in terms of their electrons. They identify the...

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...

Neatly organized and easy-to-read, this chart summarizes five different molecular shapes: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. It associates shape with electron pairs and atom arrangement, and...

A simple worksheet that allows junior chemists to chart the number of subatomic particles for various atoms in the form of a data table. It also requires them to write nuclear symbols for different atoms and isotopes. This would be a...

A huge collection of slides introduces chemistry learners to the periodic table of elements, electron configuration, and electronegativity. It opens with the history of today's periodic table, and then details the arrangement. After...

In this ions instructional activity, students complete a graphic organizer by filling in the number of protons and electrons plus the charge of the given ion.

In this static electricity worksheet, students experiment with balloons, plastic bags and flannel clothes to observe attraction and repulsion of objects. Students complete three data tables indicating the charge on the objects and if...

For this molecular geometry worksheet, students are given the directions and 4 examples as to how to predict the geometry of molecules. They determine if the molecules are pyramidal or trigonal bipyramidal.

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 thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

Students discover that charge movement through a circuit depends on the resistance and arrangement of the circuit components. In a hands-on activity, students build and investigate the characteristics of series circuits. In another...

Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. They build a conductivity tester to determine whether different objects are...

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

Use this word search to practice physical science vocabulary words. This word search allows you to determine the amount of columns and rows you would like to include; however, when you change the amount columns and rows, the word list...
