Investigating Chromatography: selecting variables part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a classroom investigation where students separate pigment in dyes in order to learn about mixtures and solutions. They use chromatography to design and experiment with a single variable to answer a question about which ink will separate the most - has the greatest variety of pigment.

Sinking Water: A Connection With Glaciers, Ocean Currents and Weather Patterns part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This lesson has activities where students will learn about buoyancy and explore how hot water rises and cold water sinks. As an extension and real-life application, students will see that glacial run-off is occurring at a rapid pace and the cold glacial water could potentially change ocean currents thus influencing global climates.

Freezing and phase change: How do you make ice cream? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an extension where students freeze a liquid, making ice cream.

How Can You Speed Up Mixing? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity helps students understand how mixtures are formed. They will make predictions regarding the rate of mixing. Students should report that the variation of heated water and crushed sugar creates the shortest mixing time.

Tic Tac Toe - Pick 3 in a Row Atomic Model Assignment part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a summary/assessment assignment which allows for differentiation and student choice. Students are assessed in their knowledge of the atomic model and the arrangement of elements on the periodic table.

Why is the Sky Blue? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This hands on lab helps explain why the color of our sky/upper atmosphere appears blue in color. Students will be able to simulate how light from the sun is scattered by our atmosphere to create blue light.

Layering Liquids part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity can be used to teach concepts how different densities of liquids can be layered and/or how the salinity of water affects the movement of ocean water.

Trucking and Thinking Newton's First Law Of Motion part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a classroom activity where students predict and test Newton's First Law of Motion as it applied to the movement of cargo in the bed of a truck.

Investigating Sound: Vibrations are the Source of Sound part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
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.

Adjusting Your Water Heater to Conserve Energy part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
- In this lab-based activity the students will use their knowledge about the law of conservation of energy to explain the loss of heat by warm water to cold water. Then, the students will use these concepts to design and carry an experiment to determine the unknown temperature of a hot water sample.

Measuring Liquid Volume part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an inside lab experiment where the students combine primary colored liquids correctly to create a rainbow.
