Let the Sunshine in
Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...
Curated OER
Genome: The Secret of How Life Works
Students explain how DNA directs the production of proteins.
Curated OER
Necessary Nitrogen
Students view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.
Curated OER
World Wide Winds
Students recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.
Curated OER
What's the Big Deal?
Students define terms and describe where they are found and formed. In this methane lesson plan students complete an activity and describe ways in which methane hydrates impact our lives.
Curated OER
The Nitrogen Cycle
Fifth graders investigate the nitrogen cycle and examine the concepts of decomposition and nitrification. Students participate in a class discussion about the creation of waste and ammonia compounds, then using nitrogen cycle cut-outs...
Curated OER
What's In Crude Oil?
Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.
Curated OER
Does the Chicken have Anthrax (Explain I)
Students explain how each of the components of innate immunity function in the protection of the body. Following an investigation, they articulate how innate immunity functions.
Curated OER
Ions in the Environment
Learners explain the importance of the five main biogeochemical cycles. In this chemistry instructional activity, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
Is There Really Life on Mars?
Young scholars examine the work of scientists and determine how they test their theories.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
Jell-O Optics
Students observe an activity with Jell-O to learn about optics. In this investigative instructional activity students fill out a handout on the activity that helps them to investigate the index of refraction and the speed of...

Middle School Chemistry: Lesson Plans: Why Does Water Dissolve Salt?
Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.
Concord Consortium
Concord Consortium: Molecular Workbench: Water and Polar Substances
Adjust amounts of ionic charges in this simulation to see how water molecules react to polar substances in solution.
