Constructed from a single strand of thin, flexible metal, the Flow Ring is both a kinetic sculpture and a mesmerizing flow toy. With one look, you'll see why it has been called a "4th dimensional Slinky". Folds flat and pops open into a beautiful 3D geometrical shape. Slip it on your arm or a rope and watch its translational energy change to rotational energy! Centripetal (seeking the center) forces hold the bands in their curved shape as they spin along your arm, instead of "flying off on a tangent". The effect is remarkable: the Flow Ring begins spinning while simultaneously falling, creating the illusion of a silver bubble. The secret is in how the metal is wrapped--the ribbon coils through itself, forming a torus knot. Get ready to be astonished as you watch this spherical toroid ring roll, bend, and flow. Comes with storage pouch.
This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s) K-PS2-1
| Elementary || || Middle School || || High School |
| K-2-ETS1-2 |
Students can use the Flow Ring to develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem. K-PS2-1
Students can use the Flow Ring to plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on an object's motion. K-PS2-2
Students can use the Flow Ring to plan and conduct an investigation to analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull. 1-PS4-3
Students can use the Flow Ring to plan and conduct an investigation to determine the effects of placing objects made with different materials into the path of a beam of light. 3-PS2-1
Using the Flow Ring, students can plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on an object's motion. 3-PS2-2
Using the Flow Ring, students can make observations and/or take measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.
| || MS-PS2-2 |
Students can use the Flow Ring to plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and its mass. MS-PS4-2
Students can use the Flow Ring and a bright beam of light to plan an investigation to describe that waves are reflected, absorbed, or transmitted through various materials.
| || HS-PS2-1 |
Using the Flow Ring, students can investigate and 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.
Construct a loop using one meter of garden hose and a connector. Open the loop and place the Flow Ring in the ring. Reattach the connector. With a hand-over-hand motion, allow the coil to rotate as you move the loop in a circular motion. Vary the speed to allow for observations. 1-PS4-3
Shine a strong beam of light on the Flow Ring as it rotates—either on a loop or on your arms. Students can make observations of the reflection of light off the spinning coil as well as following how the shadows or reflections move at the same speed as the moving object.
Place the Flow Ring onto the arm of a student. Have the student join hands with another student. Allow the Flow Ring to roll down the student's arm and up onto the other student's arm. Maintain an up and down motion of the arms to propel the coil back and forth.
Have students stand in a large circle. Pass the Flow Ring from one student to another student in the circle as a cooperative activity.
Have students explore what factors cause the Flow Ring to 'go flat' and stop.
