Curated OER
Solar
Students study solar energy. In this renewable energy lesson students complete several lab activities using different controls and variables.
Curated OER
Angles: Angles, Angles, Everywhere
Students estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays
Curated OER
Attenuation of Light in Water
Students explore what happens to light intensity as depth increases using a light intensity logger. They construct a PVC model to hold water and identify what factors could influence the amount of light attenuation.
Curated OER
Acid Precipitation
Students test the acidity of unknown solutions. They use this information to make inferences from data given from recorded rainfall records to identify areas that receive the most acid rain.
Curated OER
Soild Waste and Recycling
For this unit of lessons, students examine solid waste and recycling. They discover the concept of decomposition. They also observe the decomposition process and make observatins.
Curated OER
Demonstrating That Light is Dissipated as Chlorophyll a Fluoresces
Learners examine the concepts of light and chlorophyll. They participate in an experiment in which the chlorophyll shows as a red ring on the test tube. They answer discussion questions to end the lesson.
Curated OER
Make Way for Wild Migrants
Learners discuss the threats facing migratory species and track the seasonal journeys of wildlife in real space and in cyberspace. Once they have gathered information from several sources, they create a portfolio to share with others...
Curated OER
Water 2: Disappearing Water
Learners will observe the amount of water in an open container over time and also examine the amount of water in a closed container over time. They then will compare and contrast the sets.
Curated OER
Watersheds
Middle schoolers discover the importance of watersheds and how they impact other bodies of water. Using a map, they identify and analyze a watershed in their local area and evaluate the health of the water nearby. In groups, they plan...
Curated OER
Determination of Phosphates
Students engage in a laboratory lesson in order to increase understanding of the impact of phosphates at the chemical and ecological levels. The lab exercise is completed with the goal of getting them to predict the outcomes and future...
Curated OER
Citizen's Role
Students discuss the role of citizens in the United States. In groups, they evaluate how the role of citizens is important when selecting Supreme Court Justices. They read articles about internest groups and complete worksheets to end...
Curated OER
Chemical Bonding
Eighth graders identify the three main types of chemical bonds. In this chemistry lesson, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.
Curated OER
Chemistry: Balancing Chemical Equations
Eighth graders practice balancing chemical equations. In this chemistry lesson, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.
Curated OER
Physical and Chemical Changes
Eighth graders distinguish between physical and chemical change. In this chemistry lesson, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took place.
Curated OER
Acid and Base Testing
Young scholars study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.
Curated OER
Acids And Bases -- Universal Indicator
Eighth graders design and perform an experiment that uses a Universal Indicator Color Guide to measure the strength of acids and bases. They also determine happens when acids and bases are mixed together. They decide which of three...
