Weather Stations: Phase Change
Source Institutions
In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.
What Causes Pressure?
Source Institutions
In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.
Bernoulli and More Bernoulli
Source Institutions
This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.
Water Fountain
Source Institutions
In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.
Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.
If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside
Convection Demonstration
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
What is a “Convection Cell”?
Source Institutions
In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.
Updrafts in Action
Source Institutions
In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.
That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
How it is Currently Done
Source Institutions
In this quick activity, learners observe how wind creates ocean currents.
Bernoulli Brain Teasers
Source Institutions
In this activity related to flight, learners conduct two simple tests to explore how lift works.
Squeeze the Stream
Source Institutions
In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.
I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.
