Write a lab report that includes the title, purpose, and conclusion

The final activity is to view some Chemistry demonstrations and document the activity and its results. This will be your lab report.

Directions: Follow the steps below to complete the assignment.

Step 1. Go to the link below to view demonstration videos.

Step 2. Choose three videos from the web site. You should view each videos several times.

Step 3. After a preliminary view of the videos, look at the document below. This document includes the information that you should document when you either view demonstrations or conduct experiments. It also includes the rubric so you will understand how to earn points.

A. The title is the name of the demonstration video. The title should concisely describe the basic concept that is demonstrated in the lab activity.

B.Purpose - State the purpose of the lab beginning with the following words, To determine:

C.Hypothesis -State the hypotheses of the lab. (The hypotheses should be an 'if/then' statement.)

D. Equipment -List the equipment used in the lab. Procedure – List the procedure used in the lab. Data Table – List the data that is generated from the demonstration. You may want to create a data table. You may also create a bullet list.

Conclusion – Write 3 paragraphs that include the following information:

Paragraph 1:

a. Introduction: State the experiment

b. State the purpose of the lab

c. State the hypotheses.

d. State the outcome

Paragraph 2:

e. Discuss at least 2 sources of error that could happen: give a detailed explanation of each and how this may affect the collected data.

Paragraph 3:

f. Conclusion: provide a final summary of the demonstration.

As a scientist working in a government lab, you have been given full control over the production of a new compound. The compound was isolated from the Eastern cypress tree, a tree which grows throughout 75% of the world and reaches maturity in 2-3 years. It was found that only the needles contain the compound of interest (shown to the right).

Choose whether you would extract from the natural source

or chemically synthesize the compound. Explain and justify three reasons that support the choice you made and one reason, that is different than anything you mentioned, why your choice might not be the best – detail required in all answers. (9 marks)

Answer the following question:

1. Name and describe, in detail, two reasons why an LD50 values isn’t necessarily useful for someone to know. Pick ONE of the two reasons you described and explain an experiment you could perform to try and help make it more useful to humans. You can have an unlimited budget and access to anything you need that exists currently however you are not allowed to experiment on humans. (6 marks)

Biology help key Question 1 Lesson 11 

1. Farmed salmon can be genetically modified to reach market size in half the time of normal fish, and cost half as much to feed. However, entire populations of wild fish could be endangered by mating with bioengineered fish that are released into the wild, with disastrous consequences for the ecosystem. Why do you predict this is the case? Use your knowledge of genetics, and of genetic disease to explain how genes in isolated populations can impact the larger population (25 marks) 5 marks each for organization, ideas, proper terminology, creativity, and answering all aspects of the question.
