Separation of a Mixture of Solids
The objective of this experiment is:
* To become more familiar with the separation of mixtures of solids
* Separating a mixture
* Calculating the percentage of mixture

Lab 2: Separation of Mixtures and Solids
Purpose: The purpose of this lab is to become familiar with the separations of mixtures and solids.
Data Table 1: Experiment Data |
| Grams | Percentage of Mixture |
Iron Filings | 2.0g | 26.67% |
Sand | 1.6g | 21.
Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.
Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Ar
In this experiment I tested different light intensities. I tested a normal fluorescent light bulb, a 100-watt light bulb, a 25-watt light bulb, and a 15-watt light bulb. I was surprised to find that the control plant grew the most at 135 mm. The 100 watt plant grew the least at 0 mm

In this experiment, we measured the mass of 4 gasses; oxygen, carbon dioxide, helium, and lab gas. We took a Ziplock bag, and turned into a non-stretchy balloon, and filled with each gas and measured the apparent mass then calculated the actual mass, then find a ratio between the mass
Problem: How are carbohydrates identified as a monosaccharide?
Hypothesis: I predict that when we add the Benedict's solution to the different types of saccharides and then boil it we will most definitally be able to determine all the information the we need to accumulate to record data resulting

The objective of this lab experiment is to prepare aspirin (acetylsalicylic acid) by reacting salicylic acid and acetic anhydride.
This purpose of this lab was to prepare aspirin using its basic component
This lab was intended to model cell size and discover why cells divide. It was proposed that cells divide because of combustion. This is not the case as it is not what was looked at in the experiment. Surface area of an object was compared to its volume and weight in this experimen
The objective with this experiment was to get more familiar with elements and compounds. An example of an element would be tungsten which cannot be broken down into simpler substances by any chemical or physical means. Compounds are simply composed of two or more elements such as sodium chloride o
Wave Nature of Light
The purpose of this lab is to investigate interference, otherwise known as the diffraction of light. A beam of light acts a wave, and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that
Basic Lab Measurements and Equipment
This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments.
Procedure: Measure Volumes and Masses
1. Obtain a 400mL beaker and record its mass in gram
To become more familiar with different types of temperature scales and how to measure temperature itself. We were also taught about due point and relative humidity in this lab as well.
There are many various ways to measure temperature. One ways is by
Title: Studying samples of water from different sources to find pollutants.
Introduction: In this lab experiment I will understand what types of pullants are commonly found in certain types of water samples. In each of the water samples I am looking to find any of the seven listed pollutants, the
There were several predominant theorists in the cognitive behavioral meta-theory. Each theorist came to their conclusions, were received, and added to therapeutic skills in different ways. Their biographical history allows for a better understanding of how they came upon their conclusions. Their the
Identity of a Liquid
What is the identity of this liquid?
I predict that if we perform tests on this liquid, then we will find it to be water because the color, odor, and appearance are all the same as water.
