Students compare and contrast the tools used by Native Americans from the Paleo, Archaic and Woodland periods. The visit and discuss a website describing inventions and the problems they solved. They use this historical information to...

Students take measurements throughout the day using a simple sundial called a gnomon. They record the results on a Data Log and convert from English units to metric (S.I.) units. Data points are plotted on the same graph and analyzed.

In this seasons worksheet, students cut out the picture cards at the bottom of the page, sort the pictures and paste them with the matching season.

Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Students investigate relative and absolute dating; determine the difference between the two dating systems; and apply this knowledge by creating a geologic timetable of their own.

Students investigate how to estimate the age and size of turtles, and examine variability in scientific data. They read an informational handout, identify the parts of the shell, measure the shell and estimate the age, and record the...

Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.

Students examine the effects of bycatching on water environments. They discover how echolocation works. They participate in a simulation of the process to use it while walking blindfolded.

Students discover the importance of watersheds and how they impact other bodies of water. Using a map, they identify and analyze a watershed in their local area and evaluate the health of the water nearby. In groups, they plan their...

Students investigate the water cycle and evaporation. They study the porosity and permeability of groundwater, and the capillary action in soil in this unit.

Students explore the steps of protein synthesis in zebrafish. They view video clips to identify the parts of a zebrafish and observe them as they sequence the developmental stages. In groups they identify the muscles and how proteins are...

Students gain factual knowledge of the nature of industrial waste at on their school site. They gain process knowledge of the laboratory techniques and collection procedures for wastewater samples.

Students survey and describe a stream ecosystem. They sample the benthic macroinvertebrate populations of a given stream and determine community structure through the use of the Chandler Index and a species diversity index.

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Learners explain the process of photosynthesis. For this biology lesson, students label the different reproductive parts of the flowers. They watch a short video then identify the leaf parts on the board.

Seventh graders examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different...

Sixth graders collect soil samples and record the location of the samples by using GPS.

Young scholars work together in groups to report on different topics related to decomposition. They answer questions and share their answers with the class. They discuss any topic that is unclear.

Learners work together to discover the concept of echolocation. They examine dolphins and their behaviors. They discuss how humans could use this information to help them in their everyday lives as well.

Tenth graders design and conduct a laboratory investigation to determine how different factors may affect the hatching and development of brine shrimp eggs.

Learners use a KWL chart and describe their knowledge of fertilization, pregnancy and birth. They watch a video of fertilization and development and create a poem, song or dance about what they have learned.

Students compare and contrast the different types of alternative fuels. They create a concept map to understand their classification. They examine the properties of matter and energy as well.

Students discover the difficulty involved in trying to isolate a target species by fisherman. They discuss this issue and its problems as a class. They examine how bycatching affects their lives.

Students provide names of viral diseases that they would possibly like to be infected with today; listing them on the Smart Board. They then come to an agreement about what virus to use and use beakers of fluids to simulate how viruses...
