It is the most common element in the human body... A: Carbon, B: Hydrogen, C: Oxygen, D: Calcium
What is C. Oxygen. It makes up almost 63% of the average human. Following, are major elements and the percentages of the human body that they represent: Oxygen- 62.81% Carbon- 19.37% Hydrogen- 9.31% Nitrogen- 5.14% Sulfur- 0.64% Phosphorus- 0.63% Other- 2.10%

Which planet in our solar system has the most moons? 

Jupiter has 79 known moons!

100
This type of matter has a definite volume but no definite shape... A: Solids, B: Liquids, C: Gases, D: Plasma
What is B: Liquids. Liquids have a definite volume but no definite shape. Because the intermolecular forces are weak in a liquid, it is able to change its shape to conform to its container.

This geologic process changes metamorphic rock, igneous rock, and sedimentary rock into other types of rock. 

What is the rock cycle? 

Igneous rock is hardened magma, which can happen above or below ground.

Metamorphic rock has been heated and squeezed with extreme pressure.

Sedimentary rock is compacted sediments which can come from any of the other rocks.

This living animal has the heaviest brain... A: African Bush Elephant, B: Black Rhinoceros, C: Sperm Whale, D: Human
What is C. Sperm Whales. They have the heaviest brain of any living animal. The average Sperm Whale's brain weighs more than 20 pounds (9 kilograms) which is about 4 times heavier than the average human brain.

What year did American astronauts Neil Armstrong and Edwin "Buzz" Aldrin became the first humans ever to land on the moon? 

1969 - July 20, 1969

English chemist Henry Cavendish noticed that a gas was produced when zinc or iron was dropped into an acid. He called this gas "inflammable air"

What is Hydrogen. Henry Cavendish was an English chemist and physicist. He not only discovered hydrogen but also determined the mass of the Earth.

This type of water weighs the most... A: seawater B: distilled water C: tap water D: none - They all have the same weight.
What is A: sea water. It is loaded with mineral salts and weighs about a pound and a half more per cubic foot than fresh water at the same temperature.
150
Of the following, it has the longest recorded life span. A: Termite, B: Chimpanzee, C: Indian Elephant, D: Freshwater Oyster
What is the Freshwater Oyster (80 years.) The longest recorded life span for a termite is 50 years; for a chimapanzee, 50 years; and for an Indian elephant, 70 years.

These orbit the Sun just like asteroids, but while asteroids are made of rock, these are made of ice and dust. 

As a comet’s orbit takes it toward the Sun, the ice and dust begin to vaporize. That vaporized ice and dust become the comet’s tail. You can see a comet even when it is very far from Earth.

Matter that does not enter chemical reactions is described as this... A: Inhibited, B: Inert, C: Grounded, D: Radioactive
What is B: Inert. Inert matter does not enter chemical reactions.
150
This is the hardest naturally occurring substance... A: emerald B: tourmaline C: diamond D: corrundum
What is C: Diamond. Diamond is also one of the most valuable natural substances. Diamonds are crystals formed almost entirely of carbon. Because of its hardness, the diamond is the most enduring of all gemstones. They are among the most costly jewels in the world, partly because they are rare, Only four important diamond fields have been found - in Africa, South America, India, and the Soviet Union.

This animal has the highest blood pressure... A: Giraffe, B: Blue Whale, C: Elephant, D: Flea
What is A: Giraffe. Because of its extremely long neck, the giraffe must rely on its oversized heart (two feet long and twenty-five pounds!) to pump blood all the way to its head. As a result, the giraffe has the highest blood pressure of any animal: 280/180 mmHg (millimeters of mercury) at heart level when prone -- more than twice the blood pressure of an average human. Not surprisingly, because of their high blood pressure, giraffes are prone to heart attacks.
175
The planets make up this percentage of the mass in our solar system... A: 0.0135 %, B: 0.135 %, C: 1.35 %, D: 13.5 %
What is B: 0.135 % of the mass in our solar system. The Sun dominates, accounting for 99.86 % of the entire solar system's mass.

_________ are positively-charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons). __________ are negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons).

6th grade only - The atom can be broken down into three constituent parts. What are they?  

Cation         Anion      


6th grade - protons, neutron, and electrons.

Name one natural disaster and one landform that can occur when Earth's tectonic plates push against each other and build up enormous pressure?

Earthquakes and Tsunamis - The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. 

Mountains -  The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges

21This was the first genetically engineered organism. A: Corn, B: Tobacco, C: Sheep, D: Rat

What is a B. tobacco plant. In 1983, a tobacco plant, designed to be resistant to certain herbicides, was grown in Wisconsin.

What factor can determine how much gravity a planet has? 

  • Gravity is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth's surface.
  • A planet's mass and size determines how strong its gravitational pull is.

These substances control the rates of chemical reactions... A: Reactants, B: Catalysts, C: Isotopes, D: Cathodes
What is B: Catalysts. Catalysts are substances that control the rates of chemical reactions.

The largest hailstone recorded was closest to this object in diameter... A: basketball B: softball C: tennis ball D: golf ball
What is A: basketball. The largest hailstone ever recorded was 17.5 inches in diameter - bigger than a basketball.
