EXPERIMENT: MAKING OBSERVATIONS In science success often depends on making good
observations. Taking note of your surroundings is part of living in the everyday world, but true scientific observation is a skill that you must develop and practice. In this project, you will test your observation skills. You will also learn how to report your findings in a scientific report.

OBJECTIVES

Recognize a valid hypothesis.
Make valid observations.
Draw conclusions concerning what constitutes "good observations."
Write a scientific report.
In this laboratory exercise, you will choose one peanut from a bowlful and make "identifying observations" about the peanut. Then you will place the peanut back in the bowl and return later to try to find it again by using your observation skills.

Before you begin the investigation, you should reflect on the outcome. You have already learned how to write a good hypothesis. Try to identify which of the following would be a good hypothesis for this investigation.

I will identify the correct peanut.
If I make careful observations of a peanut, I will be able to identify the peanut at a later time.
Peanuts are so much alike that they cannot be separated by unique characteristics.
If you chose hypothesis 2, you are correct! Hypothesis 1 does not suggest any experimental design. Hypothesis 3 is not falsifiable. Although unlikely, it is possible that you could search through hundreds of identical peanuts and not be able to find one that is different in the sample. This doesn't mean there isn't a different one; it just means that you didn't find it.

Now, it's time to start the investigation!

Making Observations

Present Your Findings
Write a summary paragraph of 200 words discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.

Summarize your results.
According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.) If the hypothesis was not correct, what do the results of the lab indicate the correct answer is?
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Describe how the results might be applied in the real world.

it has more fizzing reaction

it has the same reacton as coca-cola and mentos witch is a fizzing reaction or chemical reaction.

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring 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.

    elongation: in which 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.

    termination: in which 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.
