Students make boats and race them. In this physics lesson, students investigate surface tension, molecules, and cohesion by competing in a class race with their boats. Students experiment with liquid soap to see how much will make their...

In this biologically important molecules learning exercise, students fill in the blank with information about carbohydrates, lipids, and proteins. Students also make notes about nucleic acids.

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...

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...

Sixth graders explore how water behaves on a penny.  In this states of matter lesson, 6th graders observe water as they add drops to a penny. This lesson helps students apply the adhesive properties of water to the water cycle.

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

In 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...

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...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Students examine the effects different substances have on proteins. They test different molecules reaction to water. They discover how the amount of water affects the shape of the protein.

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  In this water lesson students work in groups and complete several activities. 

In this chemicals worksheet, students answer 15 multiple choice questions about chemicals, compounds, inorganic and organic molecules.

In this polar molecules worksheet, learners complete a graphic organizer by writing in the bond type, electron dot diagram, and the type of compound for the chemical compounds given.

In this acids and bases instructional activity, high schoolers read about what happens when an acid or base is added to water. Students complete 6 short answer questions.

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

In this molecular geometry and VSEPR activity, 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...

Just as skin covers your body limiting what can go in and out, plasma membranes cover cells to do the same. Scholars begin with a presentation that gives overview of the structure and function of plasma membranes. Then, they learn how...

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

For this atoms worksheet, students explore the different types of bonds, name compounds, and determine charges of molecules. This worksheet has 8 true or false, 9 fill in the blank, and 5 short answer questions.

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

In this solubility worksheet, students identify substances as either ionic or molecular, define saturated solution and solubility, and calculate concentration of solutions. This worksheet has 7 short answer, 5 fill in the blank, and 27...
