Pressure—Gases, continued
Investigating Pressure—
Super Value
Activity-Stations Kit
By: The Flinn Staff
Four hands-on lab activities. Students experiment with mini Magdeburg hemispheres
to feel the strength of atmospheric pressure. In a pressure paradox experiment,
students compare the actual masses of two objects with their apparent weights
based on how they feel when held. Students will also use a syringe inside a special
“pressure bottle” to determine the pressure–volume relationship corresponding to
Boyle’s law. Finally, students use syringes to build simple hydraulic systems to study
Pascal’s law. Each activity requires approximately 15 minutes. Detailed student
instructions and Teacher Notes are provided. Standard laboratory equipment, such as
support stands, clamps, graduated cylinders, balances, beakers, bicycle pump with
pressure gauge and scissors, are required and available separately.
Super Value Kit is complete for 12 student groups. All materials are reusable.

AP7201 Investigating Pressure—Super Value Activity-Stations Kit $110.00
AP6884 Bicycle Pump with Gauge and Release Valve 76.35
AP7669 Plastic Bottle, 1-L 1.51
When the cap is in place, the bottle can be pumped up just like a tire! The pressure
can then be varied inside the bottle by adding or releasing air using the valve in the
cap. A sealed syringe inside the bottle will change volume in response to pressure
changes in the bottle and can be viewed right through the side of the bottle.
Comes with bottle, cap with mounted valve and complete instructions with laboratory
exercise suggestions. A bicyle pump is required and available separately.

Pressure Mat—
Demonstration Kit
By: The Flinn Staff
Simply place the Pressure Mat in the center of the seat of the lab stool and then
quickly pick it up—the lab stool will be “stuck” to the mat and lifted off the floor.
Place the Pressure Mat flat on a lab table and have students attempt to pick it up by
its handle—and discover just how strong atmospheric pressure really is. The thick,
durable rubber Pressure Mat will withstand years of demonstrations. Complete
instructions and a reproducible student worksheet are provided.
Note: A flat-seated, wooden lab stool, such as AP6208, is recommended for the lab
stool lift demonstration.

Hot Air Balloon Laboratory Kit
By: The Flinn Staff
Students will learn how hot air balloons lift, stay afloat and eventually descend. A
unique balloon launcher apparatus is included for safe and successful launches. Also
includes easy-to-follow instructions and all the materials needed to construct fifteen
3' x 2' hot air balloons! A heat gun or propane torch is required and sold separately. A
tissue replacement pack is available for 15 additional hot air balloons.
Complete for 30 students working in pairs. Includes Flinn Exclusive STEM
Integration Guide.
