Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.
Energy For Life
Source Institutions
In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.
Melting Ice
Source Institutions
In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.
Sea Level: On The Rise
Source Institutions
Learners will understand the relationship between climate change and sea-level rise.
Mini Glacier Meltdown
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.
Jet Propulsion
Source Institutions
In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.
Hot Air
Source Institutions
In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
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
Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.
Temperature Tactics
Source Institutions
In this activity, learners explore the devices used over time to measure changes in temperature.
Colors of Stars
Source Institutions
In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.
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.
That's the Way the Ball Bounces: Level 2
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
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.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
The Daily Ups and Downs
Source Institutions
In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.
Biochemistry Happens Inside of You!
Source Institutions
In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
