How can we find volume if it a shape isn't easy to measure? Investigate methods for determining this as the volume of regular and irregular objects is explored in several stations. Learners discover that when the standard formula for...

Students investigate reaction rates.  In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

Candy is one of my favorite words, and it's an even better word when it relates to science. Yes, candy science can happen when you grow rock candy crystals with your class. The entire process for growing these edible wonders of nature is...

Young scholars write a balanced chemical reaction. They articulate how burning fossil fuels increase the carbon dioxide levels in the atmosphere. Students incorporate all the environmental risks involved as well.

Learners explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

High schoolers watch a "Waste Management" Power Point as well as a "Love Canal" PowerPoint (a link is provided for the second presentation). Students write the chemical formula for each chemical and convert the contamination to grams...

Learners study how chemicals can be very dangerous when not treated with care. They watch Ammonium Nitrate power point and read about accidents involving ammonium nitrate: Halifax Explosion, Oklahoma City Bombing.

Students design experiments examining the effects of various solutes on water. They record results on graphs explaining any unexpected consequences of their experiments and determine if their hypotheses were correct.

Students investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of alpha...

Pupils explain how equilibrium quantities are changed by temperature, pressure or different concentration of substances. They work together to complete equilibrium equations. They identify the relationship between absorption of light and...

Learners are introduced to Chernobyl incident and the resulting environmental health impacts they watch a PowerPoint presentation, read articles and discuss what they have gained from these sources.

Students comprehend that there are risks involved with using nuclear power. They write persuasive paragraphs for and against nuclear power. Students analyze the environmental issues and risks with nuclear power.

Pupils calculate the amount of pesticide residue in selected foods for two pesticides and determine if these levels are safe. They read an article about a research study looking for metabolites of these pesticides in children. Finally,...

Students wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.

Students explore oxygen and its physical and chemical propeties.  For this investigative lesson students complete several experiments using oxygen.

Young scholars demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during...

Students distinguish between three phases of matter: solid, liquid and gas, on the molecular level. They compare and predict the relative compressibility of the three phases of matter through journal writings and drawings.

Students describe how the mass of a radioactive isotope changes with time and the factors that affect the rate of radioactive decay. They write nuclear decay equations to represent natural transmutation. This activity is accomplished...

Students conduct experiments and collect data to determine physical and chemical characteristics of acids and bases.

Students review key words used in stoichiometry such as mole, molar mass, Avogadro's number, and mass - mole relationships. They participate in a series of small experiments to explore solving stoichiometry problems in the laboratory.

Students conduct an experiment in which they extract the greatest number of grams of caffeine from four bags of tea. They conduct Internet research, conduct the experiment, and record their observations and data.

Students will work in groups to design and conduct an experiment to identify amino acids found in an unknown solution. This lesson is taught in three sections: (1) Introduction to chromatography (2) Experimental design session (3)...

Students analyze and compare laundry bleaches by testing their oxidizing powers. They conduct their lab experiment, compare/contrast their results with other students' work, and complete a worksheet.

High schoolers colloborate in a lab experiment. No OBJECTIVES.
