Students record hourly reading for water height for 24 hours and determine whether a location experiences diurnal, semi-diurnal or mixed tides. Links are present for the information. Students predict high and low tide, and answer a set...

Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.

Students observe the effect of light on plants. They illustrate the exchange of gases between the atmosphere and the plant. Students see that plants are part of many natural cycles. They investigate how green plants use the sun's energy...

Students participate in an experiment to define a parts-per-billion solution. In this ecology lesson, students select a second substance to create a parts-per-billion solution and observe and record their results. Students work in groups...

Students explain the importance of the five main biogeochemical cycles. In this chemistry instructional activity, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...

Sixth graders use the scientific method to test variables of evaporation. In this evaporation lesson plan, 6th graders test a wet handprint on a paper towel and relate this experiment to weather conditions.

Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...

Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.

Students understand the purpose of an aquifer. In this aquifer and groundwater lesson, students build a model aquifer find its relationship to water usage. Students record observations as they build the layers of the aquifer.

Students conduct an experiment.  In this salinity lesson plan, students learn about sea ice, why it is important and how changing amounts can affect the sea.  Students conduct an experiment to find out the effects of salinity...

Fourth graders investigate the different types of precipitation and conduct a hail experiment. They identify the types of precipitation during a slideshow, and define key vocabulary terms. Next, in small groups they follow the...

Students assess macro-invertebrates from a stream. For this science lesson plan, students observe, classify and identify organisms found in a stream. A lab station is constructed at the stream sight and students study the different...

Students listen to books about animals. For this animal sound and characteristics lesson, students listen to books and a tape of animal and then identify which animal makes that sound. Students discuss and act out how the animal acts.

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....

Students participate in a mini field trip around the neighborhood to observe nature and changes that are occurring during fall. They collect leaves of various colors, shapes and sizes on their trip. Upon return to the classroom, they...

Investigate which items float and which ones sink using this resource.  Learners participate in an activity in which they investigate this phenomena. Then they describe the experimental process, and learn how to display their results.

Students discuss what to do with a very sick fish and help it to die without much pain. As a class, they answer questions about the fish and if they believe it is suffering or not. Using their own experiences, they share how they dealt...

Students discover the harm and benefits of microbes. In this biology lesson, students explore water, nitrogen and carbon cycles. They investigate the factors affecting bacteria growth.

Students recognize the habitats of animals that live near or in a pond.  In this pond instructional activity, students examine pond water and look for pond organisms. Students observe organisms with a loupe and complete a...

Students define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. Students conduct an...

Students gain skill in the design, implementation, and reporting of a scientific research project using the scientific method. They set up an experiment to determine the effect of adding the Rhizobium bacteria to one group of legume...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Students have trout in their classroom and complete journaling, checklists, temperature checking, and ammonia level recording. In this trout lesson plan, take weekly observation records of their trout.
