Essay about lab report

1. Record your hypothesis about what will happen when Biuret solution is mixed with the solutions from test tubes 1, 2, 3, and 4 here. Be sure to use scientific reasoning to support your hypothesis.

If a car is going 60 miles per hour, how far will it go in feet in 1 minute?

To convert it to cm, you must times it by 1,000,000, so it is now 198,134,664cm3.

This section focuses on the analysis of your data. Draw a copy of the flow chart you made in class and attach it to your post laboratory assignments.

Test tube 2 will sit in the test tube rack, there is no bath needed to keep the tube at 23 degrees celsius, room temperature. This test tube that sits in the test tube rack is the control for the experiment. The control for the experiment is not the same as controlled variables. The controlled variables for this experiment were amount of 3.0% H202, amount of water, amount of time the beakers are kept in water bath, amount of enzyme per beaker, same size test tube, and same size beaker. Test tube 3 will have the enzyme sit in 37 degrees Celsius water, use a heat plate for this.

∴ 1.162*10-4m converted to micrometres is 116.2 micrometres. For comparing it with the manufacturer’s value (0.12mm), this value can be also be converted to millimetres which is 0.1162 and if rounded up, this value becomes 0.12mm.

Experiment- Experiment has three different methods. The first method is controlled experiments. In controlled experiments, researchers have a dependent variable that lets them

The experimenter begins by taking the temperature of the water and making sure that it is all at a temperature of 75 ° Fahrenheit. 2. The experimenter should start by creating the different sugar solutions. To create the control groups, 100mL of water is placed into three different cups.

In addition, this lab redesign gave my partner unlimited options on what we wanted to investigate. My partner and I wanted to test something that is involved in the equation of photosynthesis. In the end, we decided to test how the amount of carbon dioxide, represented by baking soda, affects the rate of photosynthesis. The results reflected what I believed would happen in my hypothesis. Despite all of the positives that was involved with this lab.

In this experiment we are trying to answer the question “Does salt and sugar affect the freezing point of water?” The scientists will be measuring what will happen to the freezing point (°C) of water when salt and sugar is frozen. The independent variable of this experiment is the amount of grams of salt and sugar being added into the solutions. The dependent variable of this experiment would be the freezing point of the solution measured by the thermometer. The controls of this experiment are the temperature of the environment (room temperature). The amount of solution put in each test tube,and the temperature of the ice put in each basin. Lastly, the shape of the basins.

This means that the sample of gold foil is 0.003323 cm thick. In order to convert the thickness into micrometers, the following conversion must be used:

The next section, experimental methodology, describes how the experiment was setup, carried out, and the conditions in which the experiment took place. Section 3 displays the results that were obtained from the experimental procedure, as well as provides a brief description as how the data were evaluated. Section 4 attempts to create a logical interpretation as to what the results mean, as well as identify any potential errors that may have skewed the results. Finally, section 5 summarizes the report, and suggests conclusions for the results posed throughout the experiment and potential solutions to errors discussed in section 4.

In an insulated container, you mix 200. g of water at 80ºC with 100. g of water at 20ºC. After mixing, the temperature of the water is 60ºC.

out how small Mars really is. The mass of Mars in scientific notation is 6.4185

A red blood cell is 8 μm in diameter. If drawn 100 times larger than its actual size, what diameter will the drawing be in mm? A. B. C. D. 0.08 mm 0.8 mm 8 mm 80 mm
