Vector generated image of Ball and Ring Gravesend's:Thermal expansion of solids and cavities. Most materials when heated will expand (water being one exception when its temperature is close to zero degrees Celsius). If various metals are heated in a Bunsen flame then they will expand....

Painting of Walruses ( Odobenus rosmarus),Habitat Walruses prefer to inhabit areas with ice floes in the shallower regions near the coasts of Arctic waterways. Their seasonal migration patterns coincide with the changes in the ice. In the winter, walruses move south as the Arctic ice expands, and...

Painting of Atlantic walrus ( Odobenus rosmarus rosmarus), Habitat Walruses prefer to inhabit areas with ice floes in the shallower regions near the coasts of Arctic waterways. Their seasonal migration patterns coincide with the changes in the ice. In the winter, walruses move south as the Arctic...

Painting of Lungs Inspiration:During Ispiration the the air is taken in and th lung expands to take more oxygen.

Vector generated Image of Bar Breaker: This instrument permits the fundamental heat expansion and contraction experiment anddemonstrates the enormous forces involved. A strong cast iron base is fitted with a gasburner tube. A strong steel bar rests in the base and can be heated by the gas so...

Vector generated Image of Smart Q Breathing Rate Belt:The Breathing Rate Belt is used with the Smart Q Differential Gas Pressure Sensor (±10 kPa range) to measure breathing rate. The Breathing Rate Belt is a wide nylon belt that can be wrapped around a persons abdomen or chest region. Fitted...

Vector generated Image of A Bourdon gauge uses a coiled tube, which, as it expands due to pressure increase causes a rotation of an arm connected to the tube. In 1849 the Bourdon tube pressure gauge was patented in France by Eugene Bourdon. The pressure sensing element is a closed coiled tube...

Vector generated Image of Cross Section of Capacitor:Although electrical current can only flow through an intact circuit, if a circuit is broken or opened up a small electrical field will exist between the two ends. By altering the opened circuit to expand the area of near-contact between the...

Painting of Occipital bone:The occipital bone, a saucer-shaped membrane bone situated at the back and lower part of the cranium, is trapezoid in shape and curved on itself. It is pierced by a large oval aperture, the foramen magnum, through which the cranial cavity communicates with the vertebral...

Vector Generated Image of Seed Germination:Germination is the process in which a seed or spore emerges from a period of dormancy. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. However, the growth of a sporeling from a spore, for...

Painting of Black woodpecker ( Dryocopus martius):The Black Woodpecker, Dryocopus martius, is a large woodpecker, 40-46 cm long with a 67-73 cm wingspan.It lives in mature forest across the northern palearctic. It is the sole representative of its genus in that region. Its range is expanding in...

Painting of Colored iris:The iris is a membrane in the eye, responsible for controlling the diameter and size of the pupil and the amount of light reaching the retina. "Eye color" is the color of the iris, which can be green, blue, or brown. In some cases it can be hazel (light brown)....

Painting of Dilation of the Cervix during the Birth of a human baby :During the first phase of labor, the cervix dilates (opens) from 0-10 cm. This phase has an early, or latent, phase and an active phase. During the latent phase, progress is usually very slow. It may take quite a while and many...

Painting of Breaking of the Amnion during the Dilation stage :The act of breaking the amniotic sac artificially to help induce labor.
