Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Chromatography Lab Questions Pre-Lab Questions 1. A pencil is used rather than a pen to mark the “starting line” in step two because a pen or marker while be used to place a small dot of ink in the center of the X that is made with a pencil. 2. Capillary action is filling of pores in a solid with a liquid. Capillary action is caused by spotting or absorption and is allowed to seep or flow through. 3. The type of pen that will probably give better separation in this paper chromatography

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

The investigation on the average mass of DNA with the mass of banana‚ strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana‚ strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome

Helicopter Lab (Print and Due Monday) Problem: If we change the length of a paper helicopter’s wings‚ what length of wing will make the helicopter fall slowest? Hypothesis: If we increase the length of a helicopter’s wings then it wall fall slower because the wings will spin slower. Procedure: Materials: • Scissors • 3 Paperclips • Stop Watch • Ruler (metric) • Helicopter paper template(5cm X18cm) Step by Step: 1.) Gather Materials
