TITLE: Wad a Watershed Lab INTRODUCTION: Using models is very important in science. In this lab‚ you will design a model that will help you investigate the relationship between land surfaces and water on Earth. OBJECTIVE: To design a model that will help you visualize watershed characteristics. PROBLEM: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution? HYPOTHESIS: In your own words‚ write a hypothesis about how the relationships

Part one 1. a) When hydrogen peroxide was added to manganese‚ tiny bubbles formed in the solution- intensity of (1). b)The solution did not change in temperature. c) The bubbles stopped forming after about 18 minutes. 2. After we added 2 more mL of hydrogen peroxide‚ the reaction occurred again. Again‚ small bubbles formed; intensity of (1). The solution did not change in temperature. The reaction lasted about 15 minutes. 3. After adding more manganese dioxide‚ the reaction occurred again. This

of this lab was to compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme was present

was hypothesized that the growth and seed pod production in the standard plants would increase when less competitors were present and that growth would be more affected by competition than seed pod production would be. The data in Figure 1 and Figure 2 support this hypothesis; the standard plant grew the most when it was in a container alone and‚ on average‚ produced more seeds when no competitors were present (Figure 1). Though growth and seed pod production had similar trends‚ the difference in growth

Lab #2 – Assessment Worksheet Applying Encryption and Hashing Algorithms for Secure Communications Overview In this lab‚ you applied common cryptographic techniques to ensure confidentiality‚ integrity‚ and authentication. You created an MD5sum and SHA1 hash on a simple text file on a Linux virtual machine and compared the hash values of the original files with those generated after the file had been modified. Next‚ you used GnuPG to generate an encryption key pair and encrypted a message

Lab 3: Mitosis and Meiosis Purpose: The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that
