Dilution and Concentration of Solutions
Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...
Curated OER
Light and Starch Production in Photosynthesis
Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

The Carbon Cycle
There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...
Curated OER
DNA in a "Snap"
Students observe a model of DNA and answer probing questions like, "What does this model represent?" They then work in small groups to construct an accurate model of DNA per rubric provided and present to the class explaining their model...
Curated OER
Enzymes in Action
Students explore how enzymes are important in the chemical reactions of all living things. In this enzymes and catalysts activity students complete an activity to see how enzymes change living things.
Curated OER
Plankton / Phytoplankton
Students discuss the importance of plankton in the ocean ecosystem. For this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.
Curated OER
Proteins
Students conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...

Glucose
Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
Curated OER
Dissecting Frog Embryos: Cell Membranes and Mitosis
Students use high powered dissection microscopes to dissect and examine frog embryos as well as see balls of cells that were produced by rapid division. The concept of mitosis links to the lesson.
Curated OER
DNA Fingerprinting
Middle schoolers experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
Curated OER
Amino Acids
Students explore what amino acids are, their history and how they are used in technology. In this protein lesson students identify the properties of proteins and amino acids.
Curated OER
Ice Cold
Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER
DNA
Students explore the basics of DNA and its history. In this DNA lesson plan students extract DNA from fruits and understand how it is used in forensics.
Curated OER
Kernel Power" Ethanol Fuel from Corn
Students study why corn is a biodegradable, renewable resource. For this ethanol lesson students build models and observe a chemical reaction.
Curated OER
Succession in the Classroom
Middle schoolers investigate their environment by growing plants in class. In this botany lesson plan, students discuss the lifespan of plants and animals and how they must be cared for continuously over time. Middle...
Curated OER
Identifying Food Nutrients
Young scholars pretend they are a food-quality tester. They develop a kit to test food for sugars, starches, proteins and lipids. They answer questions to complete the lesson.
Curated OER
Chloroplasts
Students study chloroplasts, their structure and evolution. In this photosynthesis lesson plan students experiment with polarized light and the production of chlorophyll.
