7-1: How does balance impact visual weight? Balance refers to the even distribution of weight in a composition. In artwork that is a sculpture and architecture, the actual weight is material in pounds or kg. In visual weight, the apparent “heaviness” or “lightness” of the shapes and forms arranged in the composition. The visual balance in composition by three ways—symmetrical balance, asymmetrical balance or radial balance. The first type of balance is symmetry; there are several symmetrical balances

Access the “Why do things float?” interactive from our Physical Science webpage. It is listed in the “Unit 2” section in the middle column Read the sidebar information on the left side of the screen and answer the following questions in complete sentences on your graph paper: What is the buoyant force? The buoyant force is the upward force that opposes gravity. What is the buoyant force equal to? The buoyant force is equal to the amount of water it displaces. How does Archimedes’ Principle explain

figure out the identity of the rock based only on its density and physical properties. With an experimental process, one will begin to compare and uncover the identity of the rock samples brought back. To begin with, is the experimental process used to determine the identity of the rock. In doing so one will need to discover the density of the rock. By measuring the rock sample with grams per milliliter is a way used to figure out the density. In starting one will need to measure the mass of the

In the “Candy Waterfall” project, the effects that size and shape have on the rate of mass flow are tested through the use of multiple different granular materials going through a funnel. In lower grade levels students are taught about the three types of matter: solids, liquids, and gases. What are not explained are materials like sand: you can stand on sand like a solid, but you can also pour it out of a bucket like a liquid. Materials like sand are known as granular materials. By testing the rate

OBJECTIVE The purpose of this experiment was to measure the density of an unknown metal object and use the measured density to insinuate a probable identity for the metal. PROCEDURE In part one of this experiment, an unknown metal object, a graduated cylinder, water, and a mass balance was first collected. The object was dried with a paper towel to avoid any water droplets and the mass balance was checked to read 0.0 g when nothing was on it. The first measurement that was retrieved as the mass

The Density Exploration lab called for us to use two different methods to calculate the density of copper with various shapes and sizes. The second experiment called for us to devise an experiment to calculate the differences in density between soft drinks. Rather than calculating using two different methods to calculate for the same substance we had two different soft drinks, diet and non-diet Coca-Cola. We then used two volumetric pipets to measure the volumes of the soft drink, then placed the

The data used from the experiment that supports the hypothesis was that the floating film canister density was 0.47 g/mL3 and it was the least dense out of the three. The floating film canister represented the crust of the Earth. The suspended film canister represented the mantle and it had a density of 0.80 g/mL3. The sunk film canister was representing the core for this experiment and it had a density of 1.34 g/mL3. Based on the data collected, that the more sand you add to the film canister, the

increase while the density of the gummy bear would decrease after it is put into water overnight. (#)This lab experimented to figure out wah changes would take to the gummy bear’s mass, volume, and density after sitting in a cup of water overnight. To do this the gummy bear's dimensions and weight was taken on the first day, along with its density and then the gummy bear was placed and water. When the gummy bear was taken out of the water on day two, the dimensions, weight, and density were taken again

ndividual Report In this project, a boat had to be made out of foam, a motor, and a propeller along with other chosen materials such as Popsicle sticks and hot glue. The goal of this project was to have the boat go straight and make it to the end of the tub that is about two point four meters in five seconds or less. A partnership of two was formed for this project, and had to test different variables to improve speed and direction, and calculate velocity, buoyancy, and efficiency. The variables

The lava lamp is a heat-powered lamp which was made in 1963. This paper discusses how a lava lamp works and how to make one at home. The liquid motion lamp, otherwise known to most people as the lava lamp, was created in England in 1963 by Edward Craven Walker. Craven Walker’s original version of the lava lamp was called the Astro Lamp. After Craven Walker had been selling the Astro Lamp for two years, he sold the United States manufacturing rights to a company in Chicago named Lava Lite. After the

Graph 12: Plot of Process Capability for Weight Percent Solids. Conclusions for Part D (Graphs 7-12): • Lube density is proportional to viscosity and weight percent solids. • Temperature will affect the viscosity and weight percent solids. o About halfway through the shift the lube will drop in viscosity from the heat. When the viscosity first drops, the weight

to figure that out. Well the thing that makes something float is called density. Density is the weight or mass something has. The weight of salt is the ocean if it was in sodium chloride would be about 120 million tons. Which got me wondering about how much would make an egg float. This floating happens because of all the different masses. Mass is mostly based on how many atoms a substance has. Mass also helps determine density. Another thing mass also determines is volume. The more the mass the more

Slope Slope = y2 - y1x2-x1 = 57.47 - 18.7460 - 20 = 38.7340 = 0.96825 g/mL The density graph has been based off all the information in the chart above. All the specific volumes and masses were recorded in this graph, in order to help compare the two and see the difference. In addition to this, a trendline was added in order to calculate the slope of the line. The slope line is a representation of the change in density overtime. More specifically, it shows the change of value in the mass of the water

The Cartesian diver was named for the French philosopher and scientist René Descartes, who invented this marvelous experiment. The main science behind this experiment is Density. Density is simply how much mass a certain material has for a volume that is given. In other words, how tightly packed and object is. Two ways that density could be increased is by adding mass to an object without changing its volume, or by keeping the mass the same, and decreasing the object’s volume. Objects will only sink

Spiritual Truths about Surface Area and Volume All objects have a certain amount of volume. They also have their own surface area. These two geometric terms have their own unique formulas. The formula for the volume has special formulas for different objects. The equation for volume of cylindrical figures is V=A(B)*H; of conic figures is V= ⅓ A(B)*H; of spheres is (4/3)()(r3). The formula for the surface area has various equations for different objects. The equations for surface area of objects

mixing. However, the phenomenon occurring is indeed possible! Density plays a key role in layering water. Density is basically the state of being compact, and can be changed by factors such temperature or dissolved salt. There are some real-life examples in nature where water is blanketing water, and the layers are not blending with each other. This may appear as an effect of putting together water with different salinities. Salt, density, and temperature play essential roles to impacting the traits

In this lab, we were trying to figure out the density of unknown metals. We determined the density at the end by first measuring the mass of the metal on a scale, then using water displacement, finding the volume of the metal. First, we decided to use metal B. We took out one piece of the metal and measured the mass by placing it on the scale. Then, we filled up the graduated cylinder with exactly 20 mL of water. After filling up the cylinder, we gently placed the metal inside and recorded the

average density through the help of the displacement method. Furthermore, the purpose of this lab was to identify the substance of the materials being tested, which in this case were a variety of pennies along with an unknown substance. In addition, the procedure being followed to get precise results focuses on calculating the mass of your substance followed by the volume of that same substance by using the displacement method which leads to calculating the density. Afterwards, the densities of each

Determining Smallest Possible Charge on Droplet Using Millikan Oil Drop Experiment Simulation Abstract: The purpose of this lab was to determine the value of the smallest charge using a Millikan oil drop simulation on the TI-83+ graphing calculator. This was done by using a program on the TI-83+ graphing calculator, where an oil droplet was placed on the screen and cursor keys were used to adjust the voltage until the droplet is suspended. The droplets radius, voltage, plate separation

the idea of density. Density is the amount of cmpactness in an object. We used oil and water, and observed the density of each substance. when pouring the two back and forth, the oil moves slower and the water moves faster and more choppy then the vegetable oil. Seeing this, oil was presumed to be more dense, so I made a hypothesis that if testing the density of oil and water, oil is more dense than its counterpart of water. After a trial of both, it turns out that water has a density of 0.96 g/ml
