In this chemistry worksheet, students examine the oxidation state in order to apply it in the laboratory setting. The sheet includes in depth background information.

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...

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...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

Cyanide, a coordination compound, is used in the extraction of gold and silver. Part 24 in the series of 36 delves into the world of coordination compounds. Classes learn, through readings, discussions, and answering questions, how to...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

In this chemistry worksheet, young scholars find the outcomes necessary for the oxidation reduction reactions. The sheet includes background information.

Viewing this slide show prepares your chemistry scholars for chemical nomenclature. Specifically, binary hydrogen compounds and ternary compounds formed from oxyacids are dealt with. One highlight is a useful graphic organizer for naming...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Try not to blind anyone with science by following the safety rules. The lesson plan encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and...

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.

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

For this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

In this kinetic molecular theory worksheet, students summarize the points of the kinetic molecular theory, they answer questions about pressure, and draw diagrams to show how suction cups, drinking straws and barometers work.
