In this atom instructional activity, students read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds....

In this atom worksheet, students read about the parts of the atom and how atoms combine into molecules and compounds. Students learn how to read a periodic table. This worksheet has 20 fill in the blank and 10 matching questions.

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

In this formulas learning exercise, students use the cross-over rule to determine the formula for compounds of the elements and polyatomic ions given. Students complete 15 problems.

In this fireworks worksheet, students read about pyrotechnics and the chemical make-up of fireworks. They are given a chart of elements and the colors they emit. Students answer three critical thinking questions about fireworks and their...

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...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

Substances with the same empirical and molecular formula must be differentiated by their structural formula. Part two in a series of 36 has pupils using chemical formulas to calculate how much of a compound is present in a given...

Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...

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...

Explore carbon and bonding with this worksheet. First, class members read a short excerpt about carbon and its characteristics. In response to the reading, they draw an electron dot diagram of carbon as well as diagrams of compounds...

Fascinating aspects of electromagnetic radiation and its use in obtaining and transferring information are described here. Learners will find the connections to current technology interesting. Although the slides are text-heavy, they do...

The ten slides in this presentation make a consice introduction to the halogen group of the periodic table of elements. The location of the group is displayed, and then the characteristics of the different halogen group members are...

This short presentation provides a convenient introduction to the nitrogen group in the periodic table of elements. A graphic displays where they are placed in the periodic table. The nitrogen cycle is mentioned and ammonia is explained....

Name is Bond, covalent bond. Through readings and answering questions, classes explore the different types of chemical bonds, their characteristics, valence shell electron pair repulsion theory, and atomic orbitals. 

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

This lesson demonstrates differentiated instruction at its best. Over the course of 2-3 class periods, young chemists have the opportunity to gain a thorough understanding of metals and their chemical properties from a variety of...

An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

The ionic formula for banana would be BaNa2. Scholars work their way through four puzzles reviewing ionic formulas. Each puzzle requires scientific knowledge as well as logic and problem-solving skills.

Nitrogen is an essential element for productive farming. An interactive lesson explores the chemical makeup of different fertilizers and their corresponding nitrogen content. The interactive challenges individuals to complete...

In this research worksheet, 10th graders locate the answers to 3 questions about elements, compounds, and the half-life of elements. They write short answers on the chart.

In this mineral worksheet, students give the name and/or symbol for elements and they distinguish between elements and compounds. They fill in a chart with subatomic particles for given elements and they determine if given substances are...
