Dancing Raisins part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an entire-class lab experiment that refreshes the concepts of sinking and floating, while introducing the concepts of bouyancy and density using the fizz from sprite (carbon dioxide gas) and raisins.

Charles' Law and Ivory Soap part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a 2 part lab activity where students record properties of various bars of soap, and make models of molecules as they are cooled or heated. Students develop a new experiment changing one variable.

Sink or Float? Inquiry Investigation part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students explore and experiment with various objects to find which materials will float or sink. They record predictions and results, and generate ideas about the properties of materials that float or sink.

Density Differences part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.

Surface Tension with soap film part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an experiment exploring surface tension in soap film.

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.

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.

Sink or Float: All Liquids Do Not Have the Same Density part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a classroom experiment where students participate or observe that different densities of liquids will yield different results in a sink-or-float activity.

Solid and Liquid Density Investigation part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students will explore with solids and liquids to discover what density is. Students will be involved in small group experiments and a full group experiment. Observing, predicting, exploring and discovering are all included in this lesson.

Walking on Water--How Do Water Striders Do It? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity provides students with a first look at water tension and its role in the life of a water strider.

Density-Mystery Canisters part of NAGT:Our Resources:Teaching Resources:Teaching Materials Collection
For this lesson, we want students to become familiar with the concept density through the experimentation of placing different substances and objects into empty prescription pill bottles and placing them into fresh ...

Investigating Plastic Polymers: Building a Model and Relating to Real Life Connections part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This is a short unit (including hands on activities) on polymers and plastics to expand our study of physical/chemical properties and changes.

Plastic Polymers: Investigating Their Flexibility part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This is a short unit (including hands on activities) on polymers and plastics to expand our study of physical/chemical properties and changes.

Sinking and Floating Water part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a classroom lab where students learn that cold water is denser and hot water is less dense than room temperature water. Students perform an experiment and relate to their background knowledge to make conjectures.

Density Of A Penny part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
A lab where the students study the density of pennies. They will discover the limitations of measurements and the value of multiple trials.

Investigating Rocks: Seeing your school's area part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
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.

Physical and Chemical Properties of Water part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a method of tying a multitude of physical (and chemical) properties together showing what makes a substance unique and identifiable. This activity is a great way to lead the students into developing their procedures, their further investigations, and yet giving them the feeling of responsibility and ownership for their learning.

Measuring and Comparing Matter part of MnSTEP Teaching Activity Collection: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.

Walking on Water--How Do Water Striders Do It? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity provides students with a first look at water tension and its role in the life of a water strider.

Bubbling Blobs part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a lab project where students observe what happens when you try to mix oil and water. It can also be used to work with density.
