Investigating Sound: Using Open Tubes To Demonstrate Beat Notes part of MnSTEP Activity Mini-collection
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.

Determining Bulk Density of Different Soil Samples and Data Analysis part of MnSTEP Activity Mini-collection
This activity combines field exercise soil collection with lab analysis of soil bulk density. Students develop a lab procedure to measure density and analyze data using Microsoft Excel computer software.

Investigating Speed and Velocity part of MnSTEP Activity Mini-collection
In this activity students will conduct an investigation on speed and velocity by designing a roller coaster model.

Flow Characteristics of the Crow River part of MnSTEP Activity Mini-collection
This activity is a field investigation where students make observations, formulate a question, construct and collect data on that question on stream flow on the Crow River in Central Minnesota

Investigating Factors that Influence Weathering of Monuments in a Cemetery part of MnSTEP Activity Mini-collection
In this field activity students will discover some of the factors that influence weathering of rock by making observations, asking questions and completing an investigation of their own design in a local cemetery.

Investigating topography caused by Glacial Lake Agassiz and glacial river Warren in the Big Stone Lake area. part of MnSTEP Activity Mini-collection
This activity is a field investigation where students will observe the topography of Big Stone Lake and generate questions about the history of this area.

Stream velocity Investigation using Inquiry part of MnSTEP Activity Mini-collection
This activity is a field investigation using science inquiry and problem solving, where small groups of students design their own experiment to determine stream velocity, collect and analyze their data, draw conclusions, and make further inferences based group discussion/collaboration.

"Mystery and the Unknown": Teaching Inquiry Through Aquatic Exploration part of MnSTEP Activity Mini-collection
This activity is a longer project that involves using inquiry to find out what kinds of aquatic animals live in our school pond. Students use direct observation, journaling, outdoor classroom techniques, research skills, collaboration, and service learning to learn about their question.

Electric Circuits - Guided Inquiry part of MnSTEP Activity Mini-collection
This is a series of lab activities where students complete experiments for open, closed, series and parallel circuits.

Investigating Motion: Calculating and Graphing Students Walking Speed part of MnSTEP Activity Mini-collection
This activity is a field investigation where students gather data on their motion and how it compares to another person.
