Students are introduced to a wide range of rock types when they examine pebbles and boulders exposed in a gravel pit. Students practice rock description and identification and categorize the rocks sedimentary, igneous, or metamorphic.

Students measure a topographic and geologic cross-section across a floodplain using simple surveying and auguring techniques in a field lab. Students also reconstruct the history of a river system.

Students are able to explain the ecological importance of phytoplankton. They describe the components that influence a phytoplankton bloom. Students interpret satellite images in order to correlate buoy data.

Students collect samples in the field, analyze them using various tools and instruments, then present their results and interpretations. They examine igneous and metamorphic rocks in detail and interpret petrologic data.

Students examine the origin of glaciers, how glacial sediments are deposited, and what sedimentary records of glaciation provide about source and process of glaciers in a field lab.

Four lessons, each following the same routine, explore the careers of a teacher, nurse, electrician, geologist, plumber, and police officer. After listening to a read-aloud and thoughtful discussion, young scholars construct puppets...

Learners view NASA images of galaxies and develop a galaxy classification scheme. They compare and contrast their classification scheme with that developed by Edwin Hubble. They recognize that galaxies are collections of billions of stars.

Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.

Students classify microorganisms into categories based on their characteristics. Pupils use a taxonomic key to identify organisms. They classify certain bacteria, protists, and viruses using a classification or taxonmic key.

In this equations worksheet, students write equations and classify them as single displacement, double displacement, combustion, combination or decomposition reactions. They also write sample equations of each type of reaction and answer...

In this plant science worksheet, students complete a concept map on the classification of plants. They fill in 9 blanks with the correct words from the list.

In this science worksheet, students figure out the answers to 15 clues going across and down associated with vertebrate animals. Students fill in a crossword puzzle.

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

Students identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.

Fifth graders observe several examples of types of rock and write about their similarities and differences in their science journals. They discuss their observations and discover that rocks are grouped according to the scientific...

Students study Carolus Linnaeus and his classification system of plants. They examine the origin of both both common and scientific names of flowers. They speculate how their favorite flowers came to be named and brainstorm about the...

Seventh graders collect and classify leaves.  In this digital leaf collection lesson, 7th graders photograph approximately 20 leaves.  Students use their leaves in a multimedia presentation and create hyperlinks to identify the...

Students describe the requirements of daytime and nightime animals for survival. They identify any behaviors that assist in the animal surviving. They create a representation for the class to view.

Students analyze a designated galaxy with a partner or in a small group.

Third graders sort and classify objects. In this sorting lesson, 3rd graders sort small objects such as cereal or candy. Then, students classify and sort objects that are living or nonliving.

Students describe how igneous rocks are formed, design a classification system to group igneous rocks and develop a controlled experiment to prove that the rate of cooling affects the size of the crystals.

Fourth graders learn how to classify animals. In this invertebrates lesson, 4th graders discuss how we classify thinks into groups and move into a discussion about classifying animals. Students learn about the differences between...

Students study the classification system of tornadoes.  In this tornado lesson students make their own tornadoes in different mediums.

Twelfth graders explore the fascinating world of orchid production including propagation, care, culture, and finishing. They complete market research and design a production schedule for an orchid crop of their choice. They write a short...
