Teach about energy, friction, rotational inertia, gyroscopic stability, and precession!

Description

This kid craze is the perfect way to bring more awesome science into your classroom! Students are already fascinated by this gadget; now you can fill in the WHY! Three weighted arms and precision bearings contribute to amazingly long spin times. This is a wonderful way to teach about energy, friction, rotational inertia, gyroscopic stability, and precession! With just a quick spin, you can instantly feel gyroscopic forces in play - easily feel the resistance to any change in orientation. A great opportunity to use a fad to teach force and motion! Colors may vary.

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

 Elementary Middle School High School K-2-ETS1-2 Students can use the Hand Spinners 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 Hand Spinners 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 Hand Spinners 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-PS4-1 Students can use the Hand Spinners to plan and conduct an investigation to provide evidence that vibrating materials can make sound and that sound can make materials vibrate. 1-PS4-3 Students can use the Hand Spinners 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 Hand Spinners 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 Hand Spinners 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. 4-PS3-1 Using the Hand Spinners students can conduct an investigation and use evidence to construct an explanation relating the speed of an object to the energy of that object 4-PS3-4 Using the Hand Spinners students can apply scientific ideas to design, test, and refine a device that converts energy from one form to another. 5-PS1-3 Using the Hand Spinners students can make observations and measurements to identify materials based on their properties 3-5-ETS1-3 Using the Hand Spinners students can plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. MS-PS2-2 Students can use the Hand Spinners 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 Hand Spinners 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 Hand Spinners, 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. HS-PS2-2 Using the Hand Spinners, students can use mathematical representation to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system. HS-PS3-3 Using the Hand Spinners, students can design, build, and refine a device that works with given constraints to convert one form of energy into another form of energy.

Suggested Science Idea(s)

The Double Hand Spinners offers many teachable physics concepts at all levels.

Students can start by using a single spinner to discuss all three of Newton's Laws. Then attach the two spinners together and observe how their contra-rotational motion can cancel out angular momentum.

When students get the spinner going really fast, have them carefully hold it up to their ears. Aside from the sound of the bearings, they will hear the lower humming sound, which are actually micro changes in air pressure. That sound changes as the speed changes.

The students can use the slow-motion video on their smart phones to capture detailed evidence of the fast moving spinners in their investigations or share information with other students.
