The first graph plots data from a soap density measurement laboratory. The slope of the line is the density of the soap.
__________ Calculate the slope of the line.
______________ Determine the y-intercept of the line.
y = _________ x + __________ Write the y = mx + b slope-intercept equation for the line.
[float] or [sink] The slope of the line is the density of soap. If the density of the soap is less than one gram/centimeter³ then the soap would float. If the density of the soap is greater than one gram/centimeter³ then the soap would sink. Based on the above, will this soap float or sink?
A student gathered the data seen in the table below. Plot the data on the graph.
__________ Calculate the slope of the line.
__________ Calculate the intercept of the line.
__________ cm. How far will the RipStik travel in 23 seconds?
__________ seconds. How long in seconds for the RipStik to travel 7500 centimeters?
__________ What is the slope of the line y = 2.0 + 0.15x?
__________ What is the y-intercept of the line y = 2.0 + 0.15x?
__________ What is the atomic number of Zn?
__________ What is the atomic mass of Zn?
__________ How many protons does Zn have?
__________ How many neutrons does Zn have?
__________ How many electrons does Zn have?
[Note that in an atom the number of neutrons is equal to or greater than the number of protons. Thus the more numerous nucleons are the neutrons.]
_______________ Looking only at the atomic diagram on this paper, determine the atomic number of the atom depicted.
_______________ Looking at the diagram, what is the atomic mass for the atom?
_______________ Looking at the diagram and the chart on the wall, what is the one or two letter chemical abbreviation for this element?
_______________ What is the common name for compound with the formula H2O?
_______________ In general, what color do acids tend to turn floral pigment fluids?
_______________ In general, what color do bases tend to turn floral pigment fluids?
_______________ Are lime fruits acid, base, or neutral?
_______________ Is vinegar an acid, base, or neutral?
_______________ Is cream of tartar an acid, base, or neutral?
_______________ Is water an acid, base, or neutral?
_______________ Is baking soda an acid, base, or neutral?
_______________ Is ammonia an acid, base, or neutral?
_______________ Is a bar of hand soap an acid, base, or neutral?
_______________ Is laundry detergent an acid, base, or neutral?
_______________ Is bleach an acid, base, or neutral?
The following graph is from laboratory fourteen.
Based on the graph and analysis above which object "flies" the best in terms of distance covered versus launch speed? Why?

Bl: Black hole
Mi: Milky Way
____ Twelve astronauts have walk on this nearest satellite of the Earth.
____ Known as the Morning Star, the Evening Star, and a sister planet to our planet Earth, this planet has clouds are made up sulphuric acid and carbon dioxide. This is one angry Goddess, the air is noxious, unbearable, and hot, approaching 900 degrees.
____ This is rocky planet closest to the Sun has no atmosphere, with the result being that the temperature swings wildly between 800 degrees Fahrenheit during the day and -275 degrees Fahrenheit at night. The planet has a large iron core.
____ This star at the center of the solar system, a giant sphere of hydrogen and helium, a nuclear fusion furnace.
____ This fourth planet from the center of the solar system also known as the red planet. The planet is red and dead. The largest volcano in the solar system, Olympus Mons, is found on this planet.
____ These rocks made of iron, nickel, and sometimes ice are found Between the red planet the largest planet in the solar system.
____ This is the largest member of the rocks orbiting between the red planet and the largest planet, this is considered a dwarf planet.
____ This largest planet in the solar system is a gas giant. A giant red spot can be seen, a vast cyclonic storm larger than the planet earth.
____ Beyond the largest planet is the "ringed planet." This planet is also a gas giant.
____ The ringed planet has this moon named for the Latin word for "giant". There was so much to see on this moon. There is wind, "rain", many different seasons, rivers, lakes, and oceans made of liquid methane, natural gas, an atmosphere with nitrogen but no oxygen.
____ Beyond the ringed planet is a planet unknown to the ancients. This is the first planet to be discovered using a telescope. The planet is tipped over at a 98 degree angle, the north pole now facing the sun. 42 years of sunlight will strike the north pole until the sun sets as the planet moves around the sun. This planet is now known as an ice giant.
____ This eighth planet is farthest from the sun and is named for the Roman god of the sea. This planet is an ice giant, the atmosphere makes the planet appear blue. The planet is a gas giant comprised of hydrogen, helium, and methane gas. The planet has very high wind speeds. High wind speeds means that the atmosphere has a lot of kinetic energy. But the planet is too far from the sun for the sun to be the source of the energy. Something else is creating the wind.
____ This moon of the eighth planet is named for the three pronged spear wielded by the Roman God of the Sea. This moon is highly unstable with rock and dust geysers. The massive gravitational pull of the eighth planet is tearing this moon apart.
____ This dwarf planet named for the God of the Underworld used to be the "ninth planet" but was demoted and is now called a dwarf planet. The surface appears to be frozen water ice and carbon compounds.
____ These dust and gas clouds are the birthplace of stars, these are where stars are born. The constellation Orion contains these, and the Pillars of Creation are also an example of this.
____ This is the name of type of stellar explosion. When large stars run out of fuel, they do not just "burn out" as a fire might here on Earth, large stars explode. In the process of exploding the intense pressure and heat generates elements heavier than iron including silver and gold. The gold in a wedding band was produced in one of these star explosions.
____ These objects have gravity so intense that not even light can escape their gravitational pull. Inside these there is no space, no time, these represent an edge of human understanding.
