In this lab, the object was to see what makes up a planet. With used rocks and other metal objects to find their densities and relate it back to planets makeups. Our results show that higher density, the more rock the object is made of.
Objective
The purpose of this lab is to try and figure out what planets and moons are made of. Depending on the density of the object, you can usually figure out what a planet is made of. We first need to figure out how to use the density formula to be able to apply it to our data. We know that planets are either made up of rocks and metals or gases and ice. With knowing the density, you can figure out the planets make up.
Introduction
Before this lab, we knew that the terrestrial planets are made up mostly

The units are grams for the mass, centimeters cubed for the volume and grams/ centimeters cubed for the density. For the sphere, the mass was 242.4 g and the volume was 47.7 cm^3, which makes the density of 5.08 g/cm^3. For the cylinder, the mass was 103.2 g and the volume was 34.3 cm^3, which makes the density of 3 g/cm^3. For the first rock, the mass was 334.1 g and the volume was 118 cm^3 which makes the density of 2.83 g/cm^3. For the second rock, the mass was 46.6 g and the volume was 20 cm^3, which makes the density of 2.33 g/cm^3. For the water, the density will always be 1 g/cm^3 which means the mass and volume will always be the exact same number.
We also calculated the density of a moon based on its make up or rock and ice percentage. We use the formula ( (P rock) (3.5) + (P ice) (0.9) ) / 100. When the moon is 100% rock and 0% ice, the moon’s density is 3.5 g/cm^3. When the moon is 80% rock and 20% ice, the moon’s density is 2.98 g/cm^3. When the moon is 60% rock and 40% ice, the moon’s density is 2.46 g/cm^3. When the moon is 40% rock and 60% ice, the moon’s density is 1.94 g/cm^3. When the moon is 20% rock and 80% ice, the moon’s density is 1.42 g/cm^3. When the moon is 0% rock and 100% ice, the moon’s density is .9

Higher density means that the planet or moon will be made up of usually more rocks than ice and gases. If the density it above 3.5 g/cm^3, then the planet or moon is made up of 100% rocks. If it is less than 3.5 g/cm^3 but greater than .9 g/cm^3, than the planet or moon is made up for rock and ice. If the density is less than .9 g/cm^3, the planet or moon is made up of 100% ice and
The crystals that were growing at room temperature ended up having the smallest weight out of the three. Its average weight was 28 grams. The crystals growing in the ice bath had the second highest average weight of 29 grams. The crystals that grew the largest was the one in the fridge. It ended up having an average weight of 37 grams.
Density is mass of a unit volume of a material substance, expressed as kilograms per cubic meter in MKS or SI units. Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density, while the volume is equal to the mass divided by the density. The weight of a body, which is usually of more practical interest than its mass, can be obtained by multiplying the mass by the acceleration of gravity. Tables that list the weight per unit volume of substances are also available; this quantity has various titles, such as weight density, specific weight, or unit weight. D = mass/volume
Chondrites give geologists insights on the makeup of the early solar system. Geologists are driven by understanding how the Earth came to be what it is today. Chondrites formed at the time o
Finding the Densities of an Unknown Solid and Liquid in Order to Determine What they Are
Saturn, although the second largest planet in the solar system, still comes above all with its remarkable traits. As a result of Saturn’s magnificent size, rare atmosphere, and its variety of its rings shapes and sizes, scientists are still trying to figure out how some of the features can be
Much of what is known about the Earth can be learned from observing the other planets in our solar system. Every planet has a different mass and density. That means that planets create varied gravitational pulls on each other. By testing the effects of the Earth’s orbit on that of the other planets it becomes possible to estimate an overall density for the planet. Knowing the density of the Earth is extremely important to understanding it’s interior structure. Returning to ...
The Earth’s moon is a rare body and there are very few similar to it. NASA has sent many manned and unmanned missions to Earth’s moon in order to answer the many questions they have about its composition and how it got there. The data that these missions yielded helped astronomers to develop these five theories:
In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”). Within days, he realized that these objects were not stars, they were moons. Io, Ganymede, Castillo, and Europa are known as the Galilean Moons or Satellites, collectively. During the 19th century, the first measurable physical studies of these moons became achievable when Simon de Laplace derived the satellite masses from their shared gravitational perturbations and afterward, other workers used a new generation of telescopes to measure the mass of these moons. The data collected showed that the density declined from the inner to the outer satellites. According to Adam Showman, “More recent observations of water ice on the surfaces of the outer three moons led to the inference that the satellite compositions range from mostly silicate rock at Io to 60% silicate rock and 40% volatile ices (by mass) at Ganymede and Callisto” ( 77). The Voyager flybys of Jupiter in 1979 exposed indication of extensive geological activity like Europa's fractured terrains, which probably result from tidal heating and bending...
Ultimately the development of previous inferences and observations which have developed our current model for the Earth’s composition and interior structure are a key concept in understanding our future developments towards resourcing our planet and understanding how it works to a further degree.
The gas giants are a collection of planets in our solar system. As can be told from their name, they are mostly composed of differing mixtures of gases and ices. The gas and ice composition in question varies among the different planets. This mix of gases gives much of the planets an extremely thick atmosphere. At the very center of a gas giant is a core of liquid heavy metals. The gas giants are also called Jovian planets, taken from the largest planet in our solar system: Jupiter. Due to the fact the the majority of a gas giant planet is gas, the planet isn’t very dense and therefore, very large as a result. In fact, all of the gas giants are vastly larger than all of the terrestrial planets. Another common factor of the gas giants are their large amount of moons. The terrestrial planet, Mars, has the largest amount of moons, 2. The amount of moons of Mars is dwarfed in comparison to Saturn’s and Jupiter’s moo...
Ceres is much less dense than Earth, the moon, and many other rocky bodies within the solar system. It has been suspected that Cere’s contained low density materials such as water ice, which has been shown to rise to the outer layer along with other light material. This division of layers is less pronounced inside Ceres than the moon or many other planets in our Solar System, which is what separates these other structures from planets like Earth, which is made up of a metallic core, semi fluid mantle, and outer
Scientists get a good idea of what asteroids are made of by studying them through telescopes. They can tell what an asteroid is made of by the color and brightness of the asteroid. A lot of asteroids that we have discovered are very dark and made of stone, but there are shiny ones that are made of nickel and iron.
Saturn is one of the five planets that you can see from Earth, though it will only be seen as a star figure. From miles away saturn looks like a solid planet. Looks can be deceiving because it is actually one of the least dense planets since it is a very gaseous planet. It has such low density to the point where if you put Saturn in an enormous pool of water, it would actually float! Saturn is 94% hydrogen and 6% helium and small amounts of methane and ammonia. Saturn’s layers is the rocky and icy c...
In experiment 5, we are learning about density and specific gravity in measurements. Density is measured by mass divided by volume in order to get the ratio of the mass of an object to its volume. Specific gravity, on the other hand, is the density of a substance divided by the density of water and will cancel out the units in order to get a unitless measurement. Mass and Volume can be measured in two different ways, first mass can be calculated by directly placing it on the triple beam scale directly, or by weighing the difference. Volume can be calculated by displacement in the graduated cylinder or by calculating its dimensions. In this experiment, the objectives were to calculate the density of a solid by measuring its mass and volume,
In our solar system, there are a vast variety of space rocks. Space contains comets, asteroids, and meteors that rush through space, but don’t make it to Earth because they burn up along the way. This is due to the amount of friction that is produced on its journey through space. Comets, asteroids, and meteors are only a few objects that orbit through space and in our solar system. As a result, these various space rocks fly throughout our solar system, creating a bunch of chemistry. Comets, asteroids, and meteors are commonly put together in a group because they are all basically the same thing. One thing that comets, asteroids, and meteors all have in common is that they are rocky objects that orbit the sun. A lot of these space rocks originated from the Asteroid Belt, the Kuiper Belt and the Oort cloud, continuing almost to the next star system! We are able to study these space rocks using probes and infrared rays. Asteroids, comets, and meteors are commonly used terms for the objects moving through our solar system, but these rocks have a bigger meaning.
