Engage your students with this all-in-one pressure kit! Four hands-on lab activities allow students to explore the fundamental principles related to pressure. 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. Most of the supplies included in the kit are completely reusable! 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 but not included. Enough materials are provided for three lab stations for each activity.
