How do you make oobleck?

Oobleck gets its name from the Dr. Seuss book “Bartholomew and the Oobleck,” which tells the story of a king who is bored with the weather until a green sticky substance falls from the sky. The oobleck will behave like a solid at times, as it can be picked up and rolled around in a person's palms. Once the person stops rolling, the mixture turns to liquid and pours through the fingers. Applying pressure to the mixture increases its viscosity, or thickness, so tapping the surface of the mixture quickly feels like a solid. This action forces the corn starch molecules together so the mix..

What are some facts about manganese?

The history of man's use of manganese reaches back to the Stone Age. Cave paintings estimated to be between 24,000 to 30,000 years old were made with pigments that were created from naturally formed oxides of manganese found in the earth. The Ancient Romans created weapons that were superior to those of their enemies by using manganese to increase the strength of their metalwork.Like the similar-sounding element, magnesium, manganese was first mined in ancient times in the Magnesia region of Greece. It is the 12th most abundant element found in the Earth's crust. The majority of the ..

What are examples of a habitat?

There are four basic components to every habitat. Those components are food, water, shelter and space. Food and water are two very essential components of an organism's habitat. Without the two, the organism could not survive. Food is different for each organism. It could be plant or animal. In some cases, such as with plants, food is the soil in the ground.\nShelters are where organisms live and protect themselves during weather or climate conditions that put them at risk. It also protects the organism from other animals or predators. Shelters may include trees, nests, rocks and hives, a..

What is the maximum amount of electrons that can be contained in each subshell?

According to Armstrong Atlantic State University, subshell s can hold up to two electrons, subshell p can contain six electrons at most, subshell d can be occupied by up to 10 electrons and subshell f can contain up to 14 electrons. In theory, subshell g could contain up to 18 electrons. However, no element with an O shell and a g subshell has been discovered as of 2014.

What are some slogans related to the plight of endangered animals?

As of 2014, slogan examples that concern endangered animals are as follows:\n“No compassion, no peace. Know compassion, know peace.”\n“I don’t eat my friends.”\n“Feed them, don’t eat them.”\n“Eat beans, not beings."\n“Stop the blindness and show some kindness.”\n“There’s no excuse for animal abuse.”\n“Being cruel isn’t cool.”\n“Do not neglect; protect! Slowly see the affect, as the animals reconnect!”\n“Adopt, rescue, love.”\n“Hunting is not a sport. In a sport, both sides should know they’re in the game.”\n“Animals are your neighbors on this e..

How does the male reproductive system work?

Would-be sperm cells first undergo spermatogenesis in the seminiferous tubules of the testicles, notes WebMD. These coiled tubes, housed by a loose sac of skin called the scrotum, are kept at a temperate below the rest of the body to aid in sperm production, according to Jesse Bering for Scientific American.\nFrom there, the unprocessed sperm cells move through the long epididymis, which is coiled at the back of the testicles, states WebMD. The sperm cells reach maturity and gain the ability to fertilize eggs. Next, sperm cells pass through the vas deferens, a muscular tube that connects to th..

How is chlorine made?

Chlorine can also be separated from hydrochloric acid by the action of manganese dioxide. This is how the Swedish chemist Carl Wilhelm Scheele discovered chlorine in 1774.\nChlorine is a halogen and is so reactive that it's almost never found in its free state on Earth. At standard temperature and pressure, chlorine is a poisonous, pale yellow green gas. It has a pungent smell, irritates mucous membranes and burns skin.\nHowever, when chlorine is combined with other elements, it can be stable and quite useful. This can be seen when it combines with sodium to make table salt and with potas..

What are some interesting facts about the constellation Cancer?

The sun is in the constellation Cancer between June 20 and July 21. It is considered a water sign.\nThe crab that is represented in Cancer is the one sent by the goddess Hera to attack Hercules as he battled the hydra, a multiheaded water serpent. Defeating the hydra was one of Hercules' 12 labors, which were his punishment for the slaying of his family. However, Hercules killed the crab, and it was set in the stars as a constellation, along with Hercules and the hydra.\nCancer can be seen in the Northern Hemisphere in the spring and in the Southern Hemisphere in the fall. However, it is ..

How many cells are in interphase?

The G1 phase of interphase is known as gap one. The S phase is known as synthesis. The G2 phase is known as gap two. The G1 phase is a period of molecular synthesis when a newly formed cell turns on a variety of genes in its DNA to make protein. During the S phase, the chromatin, which is DNA and protein, becomes synthetically active. In the G2 phase, the cell prepares to divide. The cell does not divide until after the interphase is complete, which is why there is only one cell in the interphase.

How does wind affect evaporation?

The other major factors affecting the rate of evaporation are the temperature of the water, the temperature of the surrounding air, the level of moisture in the air and the amount of sunlight hitting the water. The temperature of water reflects the speed at which the water molecules are moving. Molecules can escape the liquid more easily when they are moving faster, and so the water evaporates more rapidly.\nSunlight contributes to heating water, particularly at the surface. The photons of light hitting water molecules excite them to faster motion. A warm body of water evaporates water very ra..
