Students participate in a simulation of how diseases are transmitted. Each student holds a test tube, with only one containing the "disease" while the others have water. They move around the room until told to stop. Using droppers to...

Students use a machine called a spectrophotometer to determine how much light is absorbed by certain substances. Students record the absorbance and the % of light transmitted for different color solutions, graph their results, and then...

Silver pennies and copper nickels are made possible by applying some chemistry. Learners use electrolysis to coat a penny with zinc sulfate and a nickel with copper sulfate. Their investigation builds an understanding of electroplating...

Learners conduct a series of tests to identify unknown compounds. In this chemistry lesson, students compare the physical and chemical properties of substances. They collect data and formulate a conclusion.

Young biologists identify parts of the body that serve as wedges (teeth and fingernails), and as levers (jaw, arms, and legs). The hands-on activities described here should be exciting for learners to perform, and should also lead to a...

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

Over a 10-year period, EPA regulations cost businesses less than $30 billion, while businesses saved over $82 billion. Scholars experiment with acids and bases to better understand the pH scale. Then they debate environmental regulation...

Students identify the various parts of the body that serve as wedges and levers, identifying the fulcrum for each body lever. They bite into carrots and apples to analyze how their jaws and teeth work, then complete three worksheets that...

In this chemistry worksheet, students examine the concept of solubility of silver chloride. The sheet has in depth concept and laboratory instructions.

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

Putty is proof that learning can be fun! Share the wonderful world of polymers with your class through an experiment. Young scientists create their own silly putty, then examine its properties.

In this chemistry worksheet, students look for the weight of acid and examine its mass using chemical equations and a laboratory procedure.

Students investigate the effects of temperature and concentration on the rate of reactions. In this "clock reaction" kinetics lesson plan, students change the concentration of one reactant and keep the second constant. An indicator is...

Students explore gases. In this chemical energy lesson, students will observer chemical reactions and infer a conclusion about reaction producing gasses.

Students gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.

In this chemistry worksheet, students examine the concept of thermodynamic equilibrium constants with intense detail. The application of the knowledge is practiced with problem solving.

Students research chemical formulas and balance chemical equations.  In this chemical equations lesson students complete a class activity on chemical equations and answer questions.

Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...

Young scholars determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore...

High schoolers define what a redox reaction is. In this chemistry lesson, students electroplate some wires in the lab. They research the application of electroplating in the real world.

Students explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.

In this lab activity, students taste different samples of lemonade - rate them and then determine the molarity of sugar and citric acid in the lemonade.

Resource provides notes on Moles and Stoichiometry. Deals with all book-keeping aspects, including as section on yields and limiting reactants. Includes lesson plans, lecture slides and notes, links to related websites, and frequently...
