Curated OER
Serial Dilution of CuSO4 and Changing the Value of Paint
Students relate solution concentration and saturation to color and compare methods of changing value and color intensity with paint solutions.
Curated OER
Can Chromatography Separate A Pigment?
High schoolers separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.
Curated OER
Color It Recycled!
Students melt old crayon stubs and mold them into interesting shapes and characters. They can add paper clips to created hanging ornaments!
Curated OER
Gold Mine
Pupils view and discuss a demonstration of how gold is mined and panned. They design and create a tunnel that has reinforcements to withstand collapse.
Curated OER
Graphical Determination of Density
Young scholars determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume...
Curated OER
Dishing the Dirt Part 2
Students explore the differences between specific soil characteristics. They participate in an experiment in which they discover soil texture. They write their observations in a journal.
Curated OER
Precipitates and Black Smokers
Students discuss how hydrothermal fluid is different from seawater and what happens to it as it passes through the oceanic crust. They observe and manipulate calcuim chloride and baking soda to comprehend how precipates form.
Curated OER
Determination of the percentage of Acetic Acid in Vinegar
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...
Curated OER
"pH and the Environment"
Eighth graders experiment and study about acids and bases by becoming involved in direct hands-on learning experiences and then relate those experiences to their own lives. They experience the Ohio River and what can be done to help...
Curated OER
Floating Candles
Students observe a combustion reaction and deduce the components necessary for the reaction to occur. They also identify and interpret the relationship between pressure, volume, and number of molecules for gasses. Finally, students use...
Curated OER
Rate of Solution Demonstration
Young scholars explore the factors that can increase the rate of dissolution for a solid. They complete a laboratory exploration in which they compare the dissolution rate of a whole sugar cube to that of a crushed sugar cube in a...
Curated OER
Ice Cream
Students explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.
Curated OER
Powering a Green Earth
Students compare and contrast renewable and nonrenewable energy. In this environmental science instructional activity, students discuss the importance of going green. They identify the different components in a power grid system.
Curated OER
Separation of Unknowns in a Liquid
Learners identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.
Curated OER
Science Show
Students research topics. They teach a lesson plan based on their chosen topic to other students.
Curated OER
2005 Hidden Ocean Expedition What's Eating You?
Analyze data and make inferences about the trophic position of organisms in the Canada marine food web. After a review of the geography and formula, discuss results and write an essay to improve the understanding of Artic food webs.
