Product Details

Perplex your students with this stunning activity! Legend has it that Greek philosopher and mathematician Pythagoras of Samos gave this cup to his students when he gave them all wine. Any students who chose to be greedy and pour wine into their cups to a level higher than permitted would watch the entire contents of the cups drain away! Your students will never forget the simple siphoning effect they create with a plastic cup, a plastic test tube and a straw. Inspire your students to investigate the dramatic effects of Bernoulli’s principle with this intriguing demonstration of pressure differentials.

Complete for 30 students working in pairs.

Performance Expectations

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts.
HS-PS2-1. Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
