Explorers set up Windogradsky columns with local mud so that they can culture microorganisms. After three and six weeks they make observations of the mud and the organisms growing in it. In this way they observe succession and relate...

Pupils study the advantages and disadvantages of bacteria.  In this bacteria lesson students draw and label the different types of bacteria.

Students examine samples of water to determine its cleanliness. They visit a waste treatment plant and/or reservoir. Students explore what protects the water supply from contamination by chemical or organize pollution. They trace the...

Young scholars make simple plankton nets and use them to collect and identify common forms of plankton. They identify and interpret plankton, as seen under a microscope, whether there was more zooplankton or phytoplankton. Finally,...

Students are asked to respond to questions such as:" Have there been surveys of the area to inventory the species?" (For example, for a wetland area, do they know what amphibians live there and how abundant they are?) Are there any...

Young scholars explore genes and the way we age. They assemble a worm collection device called a Baermann Funnel. Students collect Caenorhabditis elegans or other active nematodes from local soil samples. They observe the appearance...

Students recognize the biodiversity that exists in a wetland ecosystem. They identify individual wetland organisms. Students define, identify, and comprehend the importance of adaptations. They describe the process of metamorphosis.

Pupils search stream beds to study the life cycle and adaptations of stream insects. They explore creeks and streams to see the diversity index of creeks or streams and to find the water qualit index.

Students collect microorganisms, demonstrate correct laboratory/Gram stain procedure, and design and construct tables to organize data.

Young scholars determine the temperature of the water in a cup, measure the length of a piece of cardboard, and measure out an appropriate volume of water. This task assesses student's abilities to perform measurement and reporting skills.

Sixth graders create podcasts and video public service announcements. In this environmental advocacy lesson, 6th graders study the local watershed and become advocates for their local environment. In the process, they create podcasts and...

High schoolers construct models of microorganisms recognizing size relationships-comparing the size of viruses with the sizes of bacterial and eukaryotic cells. They put into perspective just how small microbes are by comparing the size...

Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...

Ninth graders participate in experiments to investigate the the effects of nicotine, caffeine, aspirin, alcohol, and sleeping pills on the heart rates of Daphina. They describe the relationships between common drugs and heart rates....

In this biology worksheet, students are shown how to prepare a smear and then answer some review questions that address the proper preparation of a sample.

In a series of lessons, examine the impact on humans by microcosms in the biosphere. Among the plans structured for students with different abilities and learning styles, are activities describing the symbiotic relationship, drawing the...

Here is a lab that has teenage scientists examining samples of their own blood under a microscope. Learners carefully prepare slides, then make detailed observations and identifying different types of cells using a key. 

Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.

Students investigate the concept of seeds and how they can germinate. They obtain seeds and isolate them in a rubber glove before transplanting them into the ground. The lesson includes a graphic organizer for observations or information.

Where this is not exactly a lesson plan, it is a terrific outline of how to generate biogas from an animal manure sample. If you are up for the challenge, the generator can be built by your class as a concluding project at the end of an...

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

Here is a lab activity where teens experience the respiratory system first-hand as they dissect lungs and identify key structures within the system. Although the website is written in British English with some slightly different verbiage...

Fourth graders investigate riverbanks and oxbox ecosystem at the Truckee River. They observe the plants, animals, insects and water organisms located there. Students document water samples, flow and then categorize them in class. This...

Young scholars explore epidermal cells. After following specified procedures for removing epidermal cells from their wrist, students view the cells with the use of a microscope. After creating a drawing of their observation, young...
