Drops on a Penny
In this surface tension worksheet, students predict how many drops of water they can put on a coin. They test their hypothesis and repeat their experiment three times. They record their data and average their trials.
Curated OER
Surface Tension-Driven Flows
Students learn how surface tension changes can cause fluids to flow.
Curated OER
Surface Tension On Coins
Students drop water onto clean coins to determine the tension of each coin and then to graph their findings.
Curated OER
Surface Tension
Students examine the concept of surface tension. In this surface tension lesson students complete several experiments to allow them to better understand surface tension.
Curated OER
How Many Drops?
Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

Water Properties introduction
Students list items they know and want to know about water on personal K-W-L charts. They describe what happened during the warm up activity in their science journal. Students travel to four different stations and perform the different...
Curated OER
Take a Dip: Sticky Water
Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.
Curated OER
Crazy Chemistry Lesson Plan
Learners study water molecules, cohesion and surface tension. In this molecule cohesion lesson students create chemical reactions that cause a balloon to inflate and another one that results in soap suds.

Rover Landing Design Challenge
Students examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.
Curated OER
Hitler's Lost Sub
Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.
Curated OER
Floating and Falling Flows
Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Paint Property Experiments
Young scholars identify various kinds of paints by using the scientific method. In this solvents instructional activity students collect data and identify paint samples while working in teams.
Curated OER
How Many Drops?
Learners conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny can hold.
Curated OER
Emulsion_ Compulsion
Students experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
Curated OER
Forces in Liquids
In this forces in liquids worksheet, students read their notes and answer short answer questions about forces in liquids. Students complete 6 questions total.
Curated OER
The Earth's Magnetic Field
Students explain how the earth's magnetic field works and looks. They create
their own free-floating compass using the everyday materials. After constructing their compass, they test it and determine north.
