A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

High schoolers experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Here is a PowerPoint that displays multiple organic compound structures and asks viewers to identify the formulas, isomers, or potential products after a given addition reaction. This is a comprehensive set of slides that reviews...

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...

In this organic chemistry worksheet, students solve 10 multiple choice problems about organic reactions, they write the molecular structures for the products of 20 reactions, they answer 10 short answer questions about specific groups of...

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

This five-page exam was designed for a biochemistry and organic chemistry course. It covers the molecular geometry and properties of organic comounds. Test takers identify compounds, functional groups, and isomers. They draw Lewis...

In this molecular geometry and VSEPR worksheet, students find bond angles, hybridization, determine polarity and draw orbital box diagrams of molecules. They determine molecular geometry and bond angles of given molecules and determine...

Finally, a chance for the class to play with their food! Allow pupils to simulate stomach acid with common foods, and introduce specific macromolecules into the mixture to explore characteristics of carbohydrates, lipids,...

Framed as an organic chemistry practice test, this resource could be used for a variety of purposes. Composed of 15 questions about organic compounds such as isomers, alkynes, alkenes and amines, and other topics related to organic...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Explore the making of a pinch pot using this resource. Learners discuss the properties of clay, including its molecular structure. Then, they make their own clay pot. As they work, they identify the techniques used to make a pinch pot,...

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Students discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe the...

For this science worksheet, students solve problems that are related to the concept of molecular polarity. The answers to the problems are included.

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...

All different types of bonding are covered in this PowerPoint, along with details of resulting bond and molecule shapes. The definitions of traditional molecule shapes and characteristics of behavior are very useful to assist in...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Germs, parasites, and viruses, oh my! Facilitate a lesson on viruses as individuals explore functions of Archaea, Bacteria, and Eukarya. They learn how viruses compare with other organisms in nature and how they contribute to health...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...
