It's a Gas! Or is it?

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Oceanography enthusiasts are given a series of thought experiments to consider in order to relate the solubility of gases and solids to underwater volcanoes. It is not particularly engaging to perform these thought experiments. Choose...

After collecting carbon dioxide bubbles from a cup of club soda, learners attempt to make their own lemon soda while preventing the loss of carbonation. They do so by creating a syrup before mixing the substances into the club soda....

Students describe the effects of temperature and pressure on solubility of gases and other materials.  In this investigative activity students read an article and answer questions about it. 

Examine the effects of temperature and pressure on solubility and the states of matter of ocean water. Learners make inferences about the unique chemistry of ocean water at different depths. They engage in an activity related to...

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to introduce...

Students investigate the concentrations of solutions and solubility. In this concentrations and solubility lesson plan, students compare solutions of talcum powder in water and salt in water to have a visual of solubility. They perform...

How can something we can't see be so powerful? Gas molecules make an impact! This video explains their properties: 1. Gas particles always move in a straight line. 2. They are too small to occupy any volume individually. 3. When gas...

Learners investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
