MODELING WATER EROSION LAB! 1. What is the purpose of the lab?

2. What procedure did you use to complete the lab?
Outline the steps of the procedure in full sentences.

Section II: Observations and Conclusions
3. What charts, tables, or drawings would clearly show what you have learned in this lab?
Each chart, table, or drawing should have the following items:
a. An appropriate title
b. Appropriate labels

4. If you could repeat the lab and make it better, what would you do differently and why?
There are always ways that labs can be improved. Now that you are a veteran of this lab and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. Your answer should be at least two to three sentences in length.

Writing the Lab Report

Now you will use your answers from the four questions above to write your lab report. Follow the directions below.

Section I: Overview of Lab
Use your answers from questions 1 and 2 (above) as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this lab and how it was completed. It should be one to two paragraphs in length.

Section II: Observations and Conclusions
Use your answers from questions 3 and 4 (above) as the basis for the second section of your lab report. This section provides your reader with charts, tables, or drawings from the lab. You also need to incorporate your answers to the follow-up questions (from the Student Guide) in your conclusions.

dont know the answer to this question but will get back to you with answer

I only have answers 2-4 working on 1 now and the photos don't want to work sorry Bold are the Answers Hope this Helps :)

Explanation:

2. What procedure did you use to complete the lab?

Outline the steps of the procedure in full sentences.

For the first one, it said that it was starting to rain so I chose drizzle. The slope was gentle. The surrounding terrain was plains which all of this was shown in the picture. For the second one, it was raining but not downpour so I chose steady rain. The slope was gentle. The surrounding terrain was plains which all of this is shown in the picture. For the third one, it said it was starting to rain so I chose drizzle. The slope was steep. The surrounding terrain was mountains which I believe was all in the photo. For the fourth one, it said it was raining so I chose Steady rain. The slope was steep. The surrounding terrain was mountains. For the last one, it said that it was downpouring and I chose downpour. The slope was gentle. The surrounding terrain is plains which this was all shown in the picture and down below for question three.

4. If you could repeat the lab and make it better, what would you do differently and why?

There are always ways that labs can be improved. Now that you are a veteran of this lab and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. Your answer should be at least two to three sentences in length.

If I were able to repeat the lab and do it differently I would try to do two different things to improve it. I would try to create the model in a simpler manner that allowed me to better see how the erosion factored in. I would also try to take more detailed notes on it if I were to repeat it.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
