Useful for demonstrating momentum, conservation of energy and torque! The unit is suspended by two strong cords, which are wound around the shaft of the wheel and then released. The wheel will unwind as it falls but will wind itself back up as the momentum carries the wheel upward in the opposite direction. This oscillation process will continue for several moments as the wheel slowly loses momentum and travels less each time. Instructions included.

Graduated Interval: 50ml These bottles are made of translucent and unbreakable low density polyethylene. The distinguishing feature that these bottles contain is the built-in delivery tube making it a one-piece wash bottle. These bottles are graduated on the outer surface to reflect an approximate volume of solution filled or dispensed.
Students fill one container with water at room temperature and the other with boiling water. A thermometer is placed in each container and the water temperature in both cups read before heat transfer. The metal bar is then immersed in the cups, and students observe heat lost by boiling water and heat gained in the cooler water. Each kit includes: 2 insulated containers; 2 insulated lids with slots; 1 U-shaped aluminum transfer bar; 2 thermometers 20 degrees to 110 degrees. Additional materials required: low-temperature thermometer.
Combines mathematics, geometry and aesthetics into a magical motion of surprising simplicity, beauty and fun. Its system of polymer links expand and contract almost effortlessly, changing in volume 30 times. A sturdy toy, an object of art, a tool for teaching mathematics and science - the Hoberman Sphere's universal appeal and versatility have led its owners to discover uses even its inventor never dreamed of. Children love to wear it on their heads, or climb inside. Grown-ups have proved themselves no less inventive: jugglers juggle with them. Drill teams march with them. Magicians make magic with them. Teachers teach geometry with them. Motivational speakers use them as metaphors for unity, teamwork and expanding potential. Ages 4 and up. Expands from 9.5" to 30".
15 fossil specimens represent geologic time from the Paleocene to the Recent. Some of these life forms date back 60 million years and are the forerunners of modern mammals. Grades 7-12.
The fossils in this study unit help to illustrate the major processed by which a life form is preserved as a fossil. Some of the specimens will illustrate processes such as petrification, pyritization, molds and casts, and distillation. 15 natural specimens in a compartmented container. Grades 7-12.
Specimens in this collection are representative of the varied life forms which dominated this geologic era. The dinosaurs are well-known life-forms from this era. The 15 specimens are from three major periods: Triassic, Jurassic, and Cretaceous. Grades 7-12.
