Students observe different animals with bilateral symmetry. In this biology lesson, students compare how these animals move. They discuss the evolutionary history of observed animals.

Learners perform a transection of a redworm. They discuss spinal cord injuries in humans. Students compare the ability of the redworm to regenerate the ventral nerve cord with the inability of humans to repair damage to the dorsal nerve...

Students relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature at...

Geology geniuses analyze sediment samples with a hand lens and sort according to physical characteristics. They also learn about the processes of cementation, compaction, and lithification within the rock cycle. The lesson plan is...

Learners in pairs explore the transmission of the Plague, through experimentation. Cooperative groups use the scientific method to solve the fictional problem of a bacteria spreading in the Amazon. Groups also create a vector to visually...

A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...

Students use Koch's Postulates to determine that a specific organism is the root cause of a specific disease and identify what Koch's Postulates are within a protocol. They describe symptoms and signs of diseased fruit and isolate fungal...

Students set up a stream table, observe erosion, and record data on where various sizes of sediments settle. They draw conclusions as to what kind of sedimentary rock form in what locations.

Students conduct a hands-on lab activity in which they analyze a sample of water from a local stream or pond. They introduce a fertilizer solution into the sample and analyze and describe their findings.

Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.

High schoolers analyze and record major events that occur in the development of Medaka fish eggs from fertilization to hatching. In small group, students describe the processes involved, creating a timeline of the major events in the...

Students combine the skills and concepts that they have developed to ask a simple question which can be answered on a Petri plate. They ask questions and design experiments for verification through collaboration with their classmates.

Students work in groups to remove fossils from sediments, classifying as many organisms and parts of organisms as possible into major groups. They study the data from each formation and make conclusions about the types of organisms and...

Students inspect several different specimens of insects and spiders to determine characteristics that are similar and different between the two groups. They identify the basic body structure of spiders and insects and then predict where...

Second graders examine compost piles and what invertebrates help decompose the organic matter.  In this compost invertebrates lesson students collect invertebrates found in a compost pile and examine them. 

In this health worksheet, students examine the human body and make mental connections to the target function highlighted in the sheet.

Students are introduced to the idea of soil as a habitat for many different organisms. They are introduced to the links between the biological adaptations of an organism and the physical demands of its habitat. Pupils are introduced to...

Students explore botany by examining diagrams. In this plant reproduction lesson plan, students define a list of plant vocabulary terms and identify plant anatomy from a diagram. Students complete several plant activity worksheets and...

Students study the structure of flowers. In this biology lesson plan, students observe the structure of a flower and find out what function each of the structures serve.

Students count nematodes, cestodes and crustaceans on approximately one-hundred and fifty fish. They fill out autopsy reports for external and internal parasites then complete and discuss guide questions to make inferences about parasite...

Students classify the characteristics of butterflies and moths moths. In this life cycle lesson, students identify butterflies and moths common in the state of Iowa as well as their characteristics.  Students then learn the proper...

In this activity, students use a virtual biology lab to perform investigations and learn lab procedures using compound and dissecting microscopes to look at a variety of animal and plant cells.

A brief overview of the features and functions of the two main types of microscopes.

A program will help students determine differences and similarities of the structure and function of compound light microscopes, dissecting microscopes, scanning electron microscopes and transmitting electron microscopes.
