A glowworm is the larvae stage in the lifecycle of a two-winged insect. It grows as long as a matchstick and looks a bit like a maggot. A glowworm uses its glow to attract food and to burn off its waste. It's tail glows because of bioluminescence, which is a reaction between the chemicals given off by the glowworm and the oxygen in the air. This chemical reaction produces light, which the glowworm can control by reducing the oxygen to the light organ. Insects fly towards the light and get stuck in the sticky lines that the glowworm hangs down to catch food. Glowworms also use their glow to put other creatures off eating them.]]> 2019-03-15 09:24:09 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/341663362 Hilary(12) https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/341667153 This is a torch light.It is useful for camping or when there is a blackout.]]> 2019-03-15 09:39:57 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/341667153 Fabian(39) https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/341676468    The Sapphirina or sea sapphire is a small, parasitic crustacean or copepod. Tiny and transparent, this creature is found in the marine environment all over the world. These animals don’t glow: the sparkle. The reason behind this is the iridescent, crystal plates inside the epidermal cells which catch light and reflect it back. Different species give off different colours of light, including golden, blue, etc. This display of luminescence is only in case of the males who probably use this as a way of attracting the females. They light up, and within the blink of an eye, they are gone, creating the most stupendous experience ever for the observer.  ]]> 2019-03-15 10:12:20 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/341676468 Darius Ng(7) christinakohyc https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/341679075 These is a street lamp, it is useful in dark places on the road.

The angler fish can extend both its jaws and stomach to an incredible size, allowing it to swallow prey twice the size of its entire body. The dorsal appendage is a lure called an esca or illicium that gives off light produced by symbiotic bacteria. The males of the species are reduced to a sperm-producing parasitic appendage of a female . this is called parasitic mating where the male angler fish attaches itself to the female angler fish by biting into the female's skin and using enzymes to fuse with a female . a female angler fish can carry as many as six parasitic males. All angler fish are carnivorous and they range in colour from dark grey to dark brown. their length can vary from 20 cm to more than a metre . They can weigh from 2 to 45 kilograms. The angler fish is caught is always a female because the male angler fish will spend the rest of its life joined to a female angler fish like a parasite . The two become fused together and their blood vessels will join as one.

For fireflies, 100 percent of the energy goes into making light; and accomplishing that flashing increases the firefly metabolic rates an astonishingly low 37 percent above resting values.

Fireflies are bioluminescent, which means they are living creatures that can produce light. That trait is shared with only a handful of other terrestrial insects, such as click beetles and railroad worms. The light is used to attract prey and members of the opposite gender, and warn off predators. Lightning bugs taste bad to birds and other potential predators, so the warning signal is a memorable one to those that have sampled before.
Fireflies can be found in Singapore too. It can be seen in the forest.

Bioluminescent Bacteria

Some bacteria, which live in the marine environment or the decomposition or guts of sea creatures, have the capability to produce light. Many animals live in symbiosis with these bacteria, and, in return for shelter and nutrition in their bodies, use their bioluminescence. The Angler fish, for instance, has bacteria living in its barb-like escae, which glow to give using their bioluminescence. Flashlight fish have bacteria residing in the small organs beneath their eyes while the Hawaiian Bobtail Squids give shelter to such bacteria in their mantles.]]> 2019-03-17 12:43:29 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342108498 Tan Jun Hwee (34) https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342266556
Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption, usually at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F). The structures resulting from subsequent solidification and cooling are also sometimes described as lava. The molten rock is formed in the interior of some planets, including Earth, and some of their satellites, though such material located below the crust is referred to by other terms.


A lava flow is a moving outpouring of lava created during a non-explosive effusive eruption. When it has stopped moving, lava solidifies to form igneous rock. The term lava flow is commonly shortened to lava. Although lava can be up to 100,000 times more viscous than water, lava can flow great distances before cooling and solidifying because of its thixotropic and shear thinning properties.

The Antarctic krill are among the most important animals in the Antarctic food chain, ranking right under the phytoplankton on which they feed. When krill congregate in an area (called a swarm) during the warmer months, animals from all parts of this bitter cold region get ready for a feast. This is because krill affects life from every angle in Antarctica. Krill densities can reach as high as 30,000 individuals per m3! That’s a lot of krill and food for predators. With krill comes hungry fish that are gobbled by species such as seals, penguins, and birds. Krill have numerous organs which can glow a yellow-green light for up to 3 seconds at a time. It is not known exactly why krill glow, but it is thought by some scientists that krill illuminate to avoid predators from the deep by blending into the brightness of the sky and ice above the surface. As important as krill are in the food chain, it would make sense they developed such a tactic to blend in and try to avoid the inevitable.]]> 2019-03-19 05:39:10 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342701438 Yu Ting(40) https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342814086 A torch will help to see clearly during a blackout.]]> 2019-03-19 12:43:33 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342814086 https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342835490 Marcus ng (22) ]]> 2019-03-19 13:21:37 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/342835490 Kimberlin Quek (16) https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/343167737 2019-03-20 04:19:02 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/343167737 https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/343167913 2019-03-20 04:20:08 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/343167913 Marcus Ng (22) ambiency88 https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/343257153 This is a light bulb.

US scientists have recently discovered bioluminescent millipede and have suggested that these light emitting creatures developed a brighter glow gradually over time. These millipedes may have begun to glow initially in response to living in a hot, dry environment, and then later used their glow as a warning signal in other habitats, shedding light on the evolution of bioluminescence.]]> 2019-03-23 01:03:12 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/344409373 Warren(32) https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/344419697 The candle is a light source that helps us see during a black out ]]> 2019-03-23 03:33:40 UTC https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/344419697 https://padlet.com/lee_qian_hui_a/kkfejpr1hwvm/wish/344420966 Dayven Lai (8)
Lightning  is a bright flash of electricity produced by a thunderstorm.Within a thundercloud, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge.
