Lab Questions By Zackary Conte and Justin Dvorsak The first experiment with 1 M sucrose in the bag and distilled water in the beaker had almost exactly the same results. The masses were relatively the same the difference have could been from the amount of liquid that was placed inside of each of the bags. The second experiment with 5% Ovalbumin in the bag and 1 M sucrose in the beaker had almost exactly the same results. The masses were relatively the same the difference could have been from the

Kathryn Marchessault Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

Answer to Questions 1. Describe the type of meter movement used in the analog meters. The two analog meters—namely‚ the voltmeter and the ammeter—employ the d’ Arsonval meter movement. The movement consists essentially of a movable iron-core coil mounted on a pivot between the poles of a permanent magnet. When current flows through the coil‚ it creates a torque which causes the pointer to deflect. The amount of current through the coil determines the deflection of the pointer‚ which is registered

affects the activity of amylase enzyme and the optimal temperature for fungal and bacterial amylase‚ the activity of these enzymes were tested at different temperature and times and iodine was used as indicator of presence of starch. During the experiment we observed that bacterial amylase had faster enzymatic activity than fungal amylase; bacterial amylase achieved 100% hydrolysis at 40°c and 60°c at 2 minutes time and fungal amylase achieved partial hydrolysis at 60°c at 4 minutes time.

______________________________ Week 1 Lab Goals: 1. Choose your lab group. 2. Learn about lab safety. **IMPORTANT – All students are expected to wear a lab coat and goggles in lab at ALL times. As well‚ you are not permitted to wear shorts or open-toed shoes. If you are not dressed appropriately for lab‚ your TA will dismiss you. You are permitted to return to lab with proper attire and equipment‚ but the rules for lateness will apply (see the syllabus). If you do not return to lab with proper attire and

Experiment 1: Coding In this experiment‚ you will model the effects of mutations on the genetic code. Some mutations cause no structural or functional change to proteins while others can have devastating affects on an organism. Materials Red Beads Blue Beads Yellow Beads Green Beads Procedure: 1. Using the red‚ blue‚ yellow and green beads‚ devise and lay out a three color code for each of the following letters (codon). For example Z = green : red : green. In the spaces below the letter‚ record
