Young scholars investigate how size affects large and small animals differently. In this animal lesson plan, students determine how size affects different animals by constructing their own animal out of marshmallows. Once young...

Students use the TI-83 + linked to the CBL2 and temperature probes to perform an experiment. Each of the temperature probes is placed into a different cup, one insulated and one not insulated. Each cup holds warm water. The two cups are...

Learners investigate the effect of temperature on cold-blooded animals, using a 5 x 8 inch index card to represent a dinosaur as their model organism. Students measure temperature changes that occurs at different angles to a light...

Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

Learners conduct an experiment to determine whether plants need air in order to survive and grow. They discuss natural resources, analyze slides, and observe and record data from the experiment.

Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Students investigate mammals and blubber. In this science lesson abut the sea, students perform an experiment that will help them in discovering how blubber keeps sea mammals warm.

Pupils observe and compare heat loss in various objects with surface area-to-volume ratios and transfer this comparison to the physical characteristics of animals in their environment. In small groups they conduct an experiment...

Students explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...

Fourth graders explore biology by viewing animal videos in class. In this amphibian and reptile lesson plan, 4th graders identify the key differences between reptiles, amphibians and other animal classifications. Students view video...

Field trip! The class will review what they know about organisms that dwell in freshwater ponds, then trek down to the old water hole to collect specimens for examination. This includes several web links, useful tips, and an excellent...

Learners observe and compare heat loss in different objects with surface-to-volume ratios. They transfer this comparison to the physical characteristics of animals in their environment. They focus on how whales maintain their body heat.

Second graders identify saltwater and freshwater habitats and the resources found in them. They compare and contrast the two habitats and discuss their findings. They discover the resources bodies of water can provide.

Students explore various parts of the heart and blood vessels . They begin with an overview of the components of the cardiovascular system. They see a cross section of an artery and watch how a blood clot develops.

What do a reptile and an amphibian have in common? A three-part lesson allows scholars to investigate the similarities and differences between the two types of animals by identifying specific body parts. The lesson highlights the...

Learners investigate the skin surface to body area ratios for different animals.  In this seventh/eighth grade mathematics/science instructional activity, students explore heat transfer between an animal’s body and the...

Students conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students explore the evolution and features of bacteria through a series of activities. In this biology instructional activity, students collect data and graph bacterial growth. They design a brochure about bacteria's role in society.

Middle schoolers take samples from local freshwater sources and examine them for macroinvertebrate life. They take samples from both shallow and deep freshwater environments, measure temperatures, and classify organisms found in their...

Students investigate tides and the land submerged under them.  In this intertidal field trip, Students visit the intertidal zone and observe the habitats and animals that live there.  Students view the pools under rocks where...

Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Students examine extreme environments and the characteristics that make them.  In this adaptation lesson students see how animals have adapted to these environments. 

Students identify and interpret how milk is processed and learn important concepts in food safety and quality assurance. They identify how milk is processed, the importance of food safety, and the quality assurance process. Students also...
