Getting a Grip on Hydrogen Bonds
Elizabeth Nagy, Pasadena City College
The purpose of this brief (~15 minutes) activity is for students to directly observe some of the unique properties of water that are the result of hydrogen bonds, such as capillary action, adhesion, cohesion, and ...

Ocean Acidification/Acid Rain Demonstration with a Soda Stream
Sheldon Turner, Triton College
Using a SodaStream or other household carbonation appliance to teach about acidification and its effects on the environment.

Ocean Acidification
Jennifer Bown, Clackamas Community College
Students choose shell fragments from different species of Molluscs and calculate percent lose after soaking in different ph solutions for different periods of time. They research ocean acidification and especially ...

Lab: Conservation of Mass
Leif Eggen Cloquet Middle School
This investigation is a lab where students find out if mass is created or destroyed in a closed system. Students will balance the chemical equation to re-enforce their findings.

Overnight Crystals to illustrate solubility concepts
Char Bezanson Faribault High School Faribault, Minnesota
This quick-lab provides a concrete experience with crystal formation from saturated salt solutions that can help students make solubility problems more relevant to their experience.

Sinking Water: A Connection With Glaciers, Ocean Currents and Weather Patterns
Stanley Mraz, North Park Elementary School in Fridley, MN in the Colombia Heights School District. Guided inquiry part of the lesson is based on an original activity from the FOSS Kit, Water, p. 16-18.
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.

Spotting Chromatography
Lauren Lindelof Leith Avalon School Saint Paul, MN 55104
In this mini-lab students will use chromatography to compare the mobile phase and the stationary phases of different inks used in marking pens. They will also determine the polarity of the solvents and inks. Finally, the students will use their calculated information to solve a crime.
