Lake Superior Ecology Unit
Sixth graders research Lake Superior and its ecosystem. Students investigate the lake's cycles of mixing and stratification and how these cycles affect the biology of the lake. This lesson contains five days of activities.
Curated OER
Physical vs. Chemical Change Lab
Young scholars recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.
Curated OER
Science and Technology
Eighth graders explore the roles of science and technology in today's world. They research a topic based on the uses of science in society. Students discuss medicine, power, transportation, water and sewage treatment and stereos, TVs....
Curated OER
Ecology: Symbiosis
Eighth graders identify various types of symbiotic relationships. In this ecology activity, 8th graders predict whether certain organisms can form symbiosis with other organisms. They discuss and defend their reasoning.
Curated OER
Can Chromatography Separate A Pigment?
Students 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
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...

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.
Curated OER
What's Hiding in the Air?
Fifth graders conduct experiments to study the effects of invisible air pollutants including one with a bean plant. They examine methods of invisible air pollutants.
Curated OER
Chemical Reactions
Learners work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...
Curated OER
Iron Filings
Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...

Acids and Bases
What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH.
Curated OER
How Does Mining Produce Acid Runoff?
Students examine how mining and other industry operations can lead to acid runoff. In this mining lesson students study weathering and complete a lab on it.
Curated OER
Synthesizing Pigment and Dyeing Cloth
Students create a synthetic dye and oxidize the dye and record the effects.
Curated OER
Liquid Layers
In this density worksheet, students investigate what will happen when various liquids with different densities are put into the same container. They hypothesis and make observations. Students answer 4 questions about their investigation...
Curated OER
Curds and Whey
In this chemical reaction worksheet, students investigate the reaction that makes curds and whey. They mix milk and vinegar and run it through cheesecloth to collect the solid. Students make observations, read about curds and whey, and...
Curated OER
Baking Soda and Vinegar Volcano
Students construct a volcano using baking soda and vinegar. In this earth science lesson, students explain the reaction that takes place when these two chemicals combine together.
Curated OER
Life in a Forest Stream
Students assess macro-invertebrates from a stream. In this science lesson plan, students observe, classify and identify organisms found in a stream. A lab station is constructed at the stream sight and students study the different...
Curated OER
Landfills and the Potential for Groundwater Contamination
Students examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill Model...
Curated OER
Corrosion & Rust
Students examine how and when rust and corrosion occur. In this corrosion lesson students complete an experiment to see why metals rust.
Curated OER
Acids and Bases: Together again!
Young scholars identify principles behind acid-base reactions. They predict factors that may affect an acid-base reaction. Students identify questions and concepts that guide scientific investigations.
Curated OER
Making Soap
Learners explore what chemical indicators are and use pH paper to determine if something is alkaline or basic. In this pH lesson plan students manufacture their own soap.
Curated OER
Invisible Ink
Young scholars 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.
Curated OER
Combustion Reactions
Students 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.
