Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

An online resource, this worksheet has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and...

As the title implies, this PowerPoint defines and illustrates the basic terms involved with describing matter. Phases of matter, atomic structure, and the different categories of compounds are included. Slides are simple and uncluttered....

Although biochemistry of the human body is a vital topic, it doesn't have a chapter dedicated to it in many biology textbooks. If that's the case with your text, you can use this resource as a guide for designing your own lecture and as...

In this science worksheet, pupils look for the chemistry elements and how they are combined to create molecular compounds with the help of atomic models.

Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).

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...

Don't take for granted the technology behind power packs. Build an understanding of the chemical mechanics of a battery pack that charges your phone. The simulation allows young scientists to manipulate the type of elements in a pack and...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Explore the makeup of the earth's atmosphere. Using the set of specific experiments, pupils examine the main elements and compounds present in the atmosphere. Their study extends to investigate the effects of atmospheric...

In this compounds worksheet, students compare ionic, covalent, and polyatomic compounds and give examples of each type. This worksheet has 1 matching, 3 problem solving, and 4 short answer questions.

In this algebra worksheet, students graph inequalities on number lines. Two problems are written in interval notation. The other five problems require students to graph and then write in interval notation.

Carbon as a building block for organic compounds is demonstrated by diagrams and facts for its bonding style.  Saturated and unstaturated hydrocarbons are detailed and facts about biological compounds such as proteins, nucleic...

In this acids and bases worksheet, students review the characteristics of acids and bases, pK values, factors that change the rate of reactions, and catalysts. This worksheet has 17 multiple choice questions.

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

In this compounds worksheet, students review how to name inorganic compounds and then complete 2 graphic organizers naming the cations and anions.

Learners explore elements by analyzing everyday objects and materials in class. In this carbon lesson, students define several vocabulary terms such as carbon dioxide, hydrocarbon, and carbonate. Learners view a group of items,...

In this percent composition worksheet, young scholars find the percentages of atoms in compounds and they determine empirical formulas given the percent of each atom in a compound.

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 percent composition worksheet, students calculate the percent composition of compounds using their formula masses and masses of individual elements. They solve nine problems including calculating percent composition, finding...
