Boyle’s Law Lab Purpose: To determine the relationship between pressure exerted and volume of a gas. Materials: Lab simulation. Procedure: 1. Open animation file 2. Modify the number of books that press down on the piston starting from 0 books and increasing by 1 each time until 19 books. 3. Record the pressure (# of books) and volume for 19 different pressure values. 4. Record those values in a table 5. Using the data‚ plot a graph of pressure in function of volume. Conclusion:

pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

Kalle Watts Measurement Lab 9‚ 27‚ 2012 In this measurement lab we attempted to make the most precise and most accurate measurements. We used the materials and equipment that we had to make all of our measurements. We had to deal with significant figures and also‚ we had to designate each measurement with its proper unit. The objective of this lab was to use all of our equipment we had and make the most accurate measurements

Lab 2 Physics 190 Acceleration “g” Due to Gravity – Method 2 Introduction Tonight we will measure the acceleration due to gravity again. This time however‚ we will collect more data and the analysis will be different. We will first fit the data using a second order polynomial. Recall for a mass falling from rest‚ that 1 (1.1) y a yt 2 2 Suppose a mass falls through n successively greater displacements‚ each time starting from rest. The displacements can be expressed a 2 y y t ;
