Exercise to recognize regional groundwater flow in the Cretaceous aquifers of the North Carolina and Virginia Coastal Plain and their changes through time. Includes interpreting flow before and after human withdrawals, so students can discover impacts on the groundwater system, especially for depletion and saltwater intrusion.

This activity is a field investigation in which students will gather data from a stream to calculate the discharge. They will need to interpret their findings and examine what factors could change the discharge of a stream over time.

In this field investigation students document outcrop descriptions, develop investigable questions, present findings, and interpret a sedimentary rock sequence's depositional history.

In this classroom guided inquiry lesson, students will explore the properties of rocks. Students will make observations of granite and develop a hypothesis explaining what makes a rock.

This activity is a lab presentation where students gather data about rocks from their area and hypothesize what the rocks are and where they came from.

This is a classroom activity in which students will observe, question, and investigate the relationship between the sun and the earth and how that relationship causes day and night.

This activity is an investigation regarding rotational inertia and factors that affect it.

This activity is a field investigation where students will increase their knowledge of SE MN geology including rock layers, fossils, and Karst topography. They will also learn how Karst Geology impacts our water quality.

A field investigation to the Mawikwe Bay Sea Caves of northern Wisconsin along Lake Superior in the winter. Students will investigate deposition of sedimentary rocks and weathering of the rocks to produce sea caves.

Students will observe simple plants, develop an investigable question, and form an investigation. They will document their investigation in their science notebooks.

In this activity students investigate soil pH differences and buffering capacity as it relates to acid rain, interpret and present their findings, and develop a new, experimental question.

This activity is a classroom quick lab where students explore sand, soil, and water in relation to absorption and permeability.

This activity is a guided inquiry investigation where students gather data on which soil is the best for growing plants. Student will interpret their data, and develop a conclusion from the data. The student will determine which type of soil they would like to use in the next activity of making their own terrariums. The data collected could lead to further questions, which can be investigated in some extension activities.

This guided inquiry is a laboratory investigation on soil textures where students gather and analyze data, compare findings and develop new experimental questions.

In this classroom guided inquiry lesson, students will rotate through five stations of various sound instruments to look at how length affects pitch. Student will develop a hypothesis, make observations, and draw a conclusion about what happens when the length of the vibrating sound source changes.

Open tube resonators of nearly identical length produce sound waves with frequencies very close together. The difference between the two frequenciesy is the beat note frequency heard when two resonators (musical intruments)are slightly out-of-tune.

This activity is a classroom experiment where students learn about sound. Students will use musical instruments to explore the relationship between length and pitch.

This activity is a classroom activity where students use the inquiry method to answer the question "How is sound made?" by observing different sound producers and coming up with their own conclusion.

This activity is an experiment on how sound is energy and travels in waves. Students will investigate sound using different objects in the room.

Students will investigate how sounds are made and changed, record their findings in their journal, share these findings with the class, and develop further questions about sound.
