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.

Investigating Forces: Balloon car activity part of MnSTEP Activity Mini-collection
This is a guided inquiry-based lab that investigates forces exerted on a group of student-designed and engineered "balloon cars". Each group of students is then challenged to build a "balloon car" that travels a maximum distance.

Incompressibility of liquids part of MnSTEP Activity Mini-collection
Discrepant event used to introduce hydraulics and Pascal's Principle

Investigating motors and magnetism. part of MnSTEP Activity Mini-collection
This activity is an activity where students build a motor, learn motor operation and theory, interpret their understanding through troubleshooting, and develop a new, experimental question related to the motor. One follow-up activity would be coupling their motor to a fan blade or other axle to convert electrical energy to magnetic energy into mechanical motion for real world application.

Catapults: controlled investigations part of MnSTEP Activity Mini-collection
This activity is a controlled investigation of a catapult system.

Beginning Scientific Inquiry with Water Kits part of MnSTEP Activity Mini-collection
This activity is a scientific investigation focusing on inquiry after using the Foss Water Kit. The students will pose a question, create a procedure and produce a poster showing their findings.

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.

FOSS Variables FOSS Lifeboat Investigation: Developing Investigable Question, Investigation (Experimentation), and Communicating Results part of MnSTEP Activity Mini-collection
This activity is an extension of the FOSS Variables Lifeboat investigation. Students choose a lifeboats variable to investigate, write up an experiment based on the variable to be tested, test the variable, and create a lifeboats investigation poster to share their results.

Measuring and Comparing Matter part of MnSTEP Activity Mini-collection
This activity is a lab investigation where students gather data about the masses of various solid objects found in a classroom. The students graph their data, compare their data, and draw conclusions about what kinds of materials contain more matter than others.

Investigating Ordering Planets: Math Connections and Number Sense in Science part of MnSTEP Activity Mini-collection
This set of activities is designed to help students develop an understanding of scale/distance and ordering the planets from the sun, understanding Earth's position in the solar system, and developing new ways of determining "order."
