Incredible Fun Science Learning Ideas.
- Use it to demonstrate the conservation of angular momentum
- Use it for for science expansion and contraction demonstrations.
- Use it to show the volume, surface area and diameter relationships of a sphere for physics and chemistry.
- fun way to hone motor skills and to develop great hand-eye-coordination.
Roll it around, climb inside, spin it and catch it!
You can play many different games and create many interesting effects with the Hoberman sphere. This is explained with the manual that comes with the sphere.
Angular Momentum
This amazing gadget comes with its own pulley system which allows you to hang it from the ceiling.
Pull the cord and watch the sphere contract. Release the cord and the sphere will expand again.
Whilst in the expanded position spin the sphere – while in motion, pull the cord – the sphere will contract but what happens to the speed?
Now repeat this demo in the dark! It is mesmerising!
The Hoberman sphere is a structure resembling a geodesic dome, and which can fold down to a fraction of its normal size. The scissor-like action of its joints enables it to do this.
The Hoberman Sphere is a type of spherical polyhedron (a multi-sided solid geometric form) known as an icosadodecahedron. If you know Greek, the name tells you exactly what it is: a geometric form (heron) that has 20 triangles and 12 pentagons(in Greek, ices means 20 and dodecahedron means 12!)
Hoberman Sphere for Mindful Breathing
A Hoberman Sphere toy can be used for mindful breathing. It can be used to show how the lungs fill with air and expand on the in-breath, then contract with the out-breath. It also serves as a point of focus, or an anchor, for mindful breathing.
Hold the sphere closed in front of your chest and with the in-breath, open the sphere to its full capacity. With the out-breath, close the sphere down to its smallest size. Repeat a few times
