Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. What do you think would happen if you threw a block of Styrofoam™ into the water? The Styrofoam will float

2. What would happen if you broke the Styrofoam up into lots of pieces, then threw the pieces into water? The pieces will still float

3. What

1. Form hypothesis: How do you think cutting up a material will affect its density? I think the density will be the same.

2. Collect data: Click Slice. Choose a piece of Styrofoam and drag it onto the Material Investigation tray. Record the mass and volume, then calculate the density by dividing the mass by the volume. Replace the piece, and then repeat for the remaining pieces.

|Piece |Mass (g) |Volume (cm3) |Density (g/cm3) |

|1 |4.64 g |23.2 cm3 |0.2 g/cm3 |

|2 |0.9 g |4.5 cm3 |0.2 g/cm3 |

|3 |0.58 g |2.9 cm3 |0.2 g/cm3 |

|4 |1.16 g |5.8 cm3 |0.2 g/cm3 |

|5 (if available) | | | |

3. Analyze: What do you notice about the density of the Styrofoam pieces? The density remains the same.

4. Predict: What do you think is the density of the whole block of Styrofoam? 0.2 g/cm3

5. Test: Click Reset. Drag the whole (uncut)

## Pre-1982 Pennies Lab Report

This experiment was performed to determine the difference in density between pre-1982 pennies and post-1982 pennies. In addition, we were given an unknown substance and our task was to configure what it was through calculating its volume,mass, and density. Furthermore, we were being introduced to the procedures of displacement in this experiment as well. All together, we were given the task of finding out why there was a difference in density between the two pennies. My partner, Michael Sapawa, and I first had to measure the mass of both pennies using a scale. Then we calculated the volume of the samples with graduated cylinders through the method known as displacement. We then applied our schema and drew out the formula for density, which

## Precision And Accuracy Lab Report

Abstract: The objective of the lab is to determine the volumes of the polystyrene spheres with three different measuring tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The experiment is meant to help understand the concept and application of precision and accuracy in experimental measurements. Accuracy is a measure of how closely the results of repeated measurements are to the true value of what is being measured. Precision is the variability in the results from the repeated measurements, and how close the repeated measurements were to one another. In this lab, the method for measuring the volume of the polystyrene spheres is done with the previously stated tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The standard deviation for the entire classes volumes and masses are recorded to determine the densities.

## Density Lab Report Essay

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

## Aluminum Foil Lab

This purpose of this experiment is to calculate the thickness of a sheet of aluminum foil. This experiment is necessary because the human eye cannot accurately measure the small thickness of aluminum foil with only a ruler. However, to understand the procedure one needs to understand conversion, density, and volume. Conversion is when one converts one unit to another unit using a conversion factor(e.g. 2.54cm/in). Density is how much mass there is in a certain volume(density=mass/volume) and it stays constant in a substances and mixtures that have the same composition. Volume is the amount of space that an object occupies. The experiment will consist of weighing of aluminum foil, measuring the length and width, then converting these values
