Curated OER
Triangle Exterior Angles Theorem
Learners identify the measure of missing exterior angles. For this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.
Curated OER
Investigating Pythagorean Triples
Students investigate and solve Pythagorean triples. For this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.
Curated OER
Investigating the Pythagorean Triples
Students investigate the Pythagorean triples. In this geometry lesson, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.
Curated OER
Electric Motors
Students examine the different types of electric motors including their history and classification. In this motor instructional activity students complete several experiments with different motors.
Curated OER
Scientific Notation III: Linear vs Exponential
Learners 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
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
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. For this earth science lesson, 8th graders collect data and record observations taken from outdoors. They explain why numerical values are different in...

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
Tower O'Power
Students work together to design a tower from a computer program. They manufacture the pieces with a laser cutter and compete in a competition to determine the best design for stress relief on towers. They discover the work engineers...
Curated OER
How is Your Driver Doing?
Sixth graders explore the concept of averaging of numbers and the function of a spreadsheet. Data is collected, analyzed, and displayed in this lesson. The NASCAR race results provides the basis for the collection of data.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
Scientist Simulation
Students imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein product...
