Simple Measurements
Students determine the height of objects using shadows. In this math activity, students discus methods of finding the height of items without directly measuring. Students measure shadows and figure the actual height of the object.
Curated OER
Electric Motors
Students examine the different types of electric motors including their history and classification. In this motor lesson students complete several experiments with different motors.
Curated OER
Lights On - We Have A Quorum
Students explore basic bacteriological techniques. They investigate cell to cell communication and become aware of the environmental and evolutionary implications of this communication.

Water Pressure - Observing Water Flow
Pupils discover that pressure increases the deeper the ocean becomes. They determine how water pressure differs at various depths by observing water flow.
Curated OER
Computer Science: Pendulum
Students investigate the basic properties of pendulums as a function of spreadsheets. Working in groups, they measure the period for a pendulum at six different lengths and record the results. They prepare a file using Microsoft Excel...
Curated OER
Scientific Notation III: Linear vs Exponential
Students examine the differences in exponential growth and linear growth of a system. They interpret data on graphs and develop their own charts. They answer discussion questions as well.
Curated OER
Transmission of Disease
Students provide names of viral diseases that they would possibly like to be infected with today; listing them on the Smart Board. They then come to an agreement about what virus to use and use beakers of fluids to simulate how viruses...
Curated OER
Weather Instrument Use and Application
Eighth graders measure temperature, wind speed and pressure using Skymaster SM-28. In this earth science lesson, 8th graders collect data and record observations taken from outdoors. They explain why numerical values are different in...
Curated OER
Using Magnetotactic Bacteria to Study Natural Selection
Students demonstrate that living organisms may possess incredible adaptations which enable them to survive. They observe bacteria that are able to orient themselves using the Earth's magnetic field and formulate a hypothesis as to how...
Curated OER
The Perils of Drinking Water
Learners determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.
Curated OER
A Living Watershed
Students, through this series of lessons, use local resources, speakers, print and video materials, as well as standard text materials to study the ecosystem of the local watershed.
Curated OER
A Self Directed Inquiry into the Identification of Unknowns
Learners 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.
Curated OER
Adhesion of Caulks to Surface -- Testing Product Quality
Students test the adhesive quality of commercial caulk to determine the differences in materials that are seemingly similar.
Curated OER
cDNA Sequencing By Restriction Project
Learners try to confirm the sequence of a given cDNA clone using the WWW tools and traditional restriction analysis. They grow the clone, prep the plasmid, cut the plasmid with restriction enzymes and compare their results to what was...
Curated OER
"Investigating Hazardous Materials"
Eighth graders gather Internet information on a variety of related topics concerning hazardous waste.
Curated OER
Music Technology
Students identify the features of a synthesizer and practice using them. They record different sounds using the software provided. They also examine sound waves and applications through the synthesizer.
Curated OER
Electric Current and Resistance
Students are introduced to the topics of electric currents and resistance. In groups, they distinguish the difference between conventional and electron flows and state Ohm's Law for electrical components. They calculate the resistance of...
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Camouflage and Protective Coloration: A Model of Natural Selection
Students collect data and compare whether protective coloration or camouflage provides better biological fitness in a given environment. They simulate predator prey interactions of two different species and use gene frequencies to...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Cloning of Plasmid and Spinach DNA
Students ligate fragments of genomic DNA from spinach into a vector plasmid. They perform a restriction enzyme digestion. Student use a ligated DNA molecule to transform E. coli cells. Students analyze their procedures and outcome of...
Curated OER
The Cloning of Plasmid and Spinach DNA
Students will first extract genomic DNA from spinach and perform a restriction enzyme digestion on both the spinach DNA and the plasmid using the same restriction enzyme. They then ligate the cut plasmid DNA with the cut spinach DNA in...
Curated OER
Most Troublesome Exotic Invasive Plant Species Web Quest
Students participate in a Web Quest activity in which they identify common exotic invasive plant species of the Southern Appalachian Region. After identifying the top 10 exotic invasive species, they choose one to research in depth.
Curated OER
Sheep Heart Dissection
In this dissection activity, students identify as many structures as they can while dissecting a sheep heart. This activity has 23 matching and 12 short answer questions.
