Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.
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.
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.
Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.
Volcanic Material Catapult Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.
What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
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.
Submarine: Lift Bag Lander
Source Institutions
In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.
Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.
Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Solar Convection
Source Institutions
In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.
Weather Stations: Winds
Source Institutions
In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod
Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
Changing the Density of a Liquid: Heating and Cooling
Source Institutions
Learners investigate how the temperature of water affects its density.
Where Do We Choose to Live and Why?
Source Institutions
In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.
