Looking for authentic hands-on nutritional experiments? High schoolers will perform experiments to test for the presence of vitamin C in several solutions as well as the effect of caffeine on Daphnia. They will also consider the...

Students are taught that plants produce oxygen underwater, and they design an experiment that test this question. They discuss whether plants give off oxygen, and how to measure this. Students measure the increase in dissolved oxygen...

Students sample a site with low human impact, one with moderate human impact, and a third with high human impact. Students chart the data for each site and then compare the sites and discuss.

Young scholars describe the anatomy of a virus. In this biology lesson, students compare and contrast the characteristics of bacteria and viruses. They discover the genetic adaptations of viruses over time.

Learners are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Students conduct a variety of experiments to explore protein. In this biology instructional activity, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription...

Students explore biology by identifying a diagram. In this cell anatomy lesson plan, students read a story about archeology and conduct a fictitious archeology dig in class in which they search for animal cells. Students define a list of...

Students identify the different leaf pigments and colors. In this biology lesson, students perform chromatography to separate them. They explain how light affects green leaf colors and causes falling leaves in autumn.

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Focus on terminology of the female anatomy and the various functions of each organ with a study on the pros and cons of birth control effects. This lesson plan provides a list of strategies to teach this concept for both female and male...

Students explore screening processes for biological activity.  In this deep sea lesson students complete a lab activity. 

Students compare human and dog senses. In this biology lesson, students describe different ways that dogs help humans. They research and create a presentation about a modern dog hero.

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.

Young scientists discover the importance of scientific investigation by observing live crayfish. They carefully observe the patterns of crayfish in different environments. Then they discuss their conclusions and define what all living...

Four different activities focus on the amount of trash generated and how humans can better manage waste. Learners analyze two days' worth of household garbage, test materials for biodegradability, and rate recyclability of various...

Third graders examine the nutritional value of different foods. In this health science lesson, 3rd graders create a daily log of the foods they eat and categorize them. They plan a healthy menu for their family.

Students summarize the steps of the scientific method. In this life science lesson, students explain the importance of varying only one variable at a time. They analyze possible flaws in their experiment.

Students investigate how fish use their sense of smell. In this scientific method lesson, students design and perform an experiment to investigate how fish use their sense of smell. This lesson includes statistical analysis and...

Eighth graders assess fat content of different food samples. In this biology lesson, 8th graders create a flowchart showing the transport of cholesterol in the bloodstream. They perform tests for the presence of lipids on food samples.

Sixth graders explain how soil and plants effect contaminated water in nature.  In this filtration instructional activity, 6th graders work in groups to test biofiltration units. Students determine which biofiltration units work...

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson plan, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a...

Third graders investigate how farmers get more rice from their land. In this farming lesson, 3rd graders discover things that farmers to do produce more rice. Students study photosynthesis and illustrate pictures about it. Students test...

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data, and...

Students explore the needs of plants.  In this plants biology lesson, students work in groups to perform an experiment with tomato plants.  Each group records observations in a journal, takes pictures, and interprets the...
