Scientific Method

 Quiz Next Tuesday over the Scientific Method.
 
 You can boil it down to six words.  (Kind of.)
1. question
2. research
3. hypothesis
4. experiment
5. analysis (of data collected)
6. conclusion

For details on the six words (because you do really have to know what they mean and how they fit together) please see your purple textbook beginning on p. 14.

Also submitted for your learning needs:
 What is the difference between scientific method and scientific inquiry?
What is the difference between qualitative and quantitative observations/data?

Possible short essay:  Why is it important for an experiment to be repeatable with the same results? 

Periodic Table this Friday: uranium  U 92

BioChem Lab Week!

No quiz this week.  Hooray!

It's lab week!  Double hooray!

It's  kind of gross, but really interesting.

Where did the victim eat his last meal????

See you in the forensics lab.

Here are some questions for next Tuesday's quiz.  Please be advised that there will also be questions about the nature of amino acids and proteins.  You should also study the mini-book about these subjects and stay tuned in class about "big ideas".  I will alert you to this!

Amino Acids-- how many pairs of DNA make up a code for each amino acid?

How many bases of DNA are there?

What do chains of Amino Acids create? 

What is replication of DNA?  

What is transcription of DNA?

What is translation  of DNA?

What do the last two things do?  Why are they important?

Why is it important to make a copy of DNA into RNA to "read" for amino acid production and other tasks?

What is the main function of enzymes?  Why is it important?

Explain how enzymes work-simple is best!

  

FOR FRIDAY 1-17-14

Add Uranium to the PT

Here are the links to the DNA learning center website's videos:

Transcription and translation

replication

There is also a basic translation and basic transcription  video broken down into the two different phases.  Transcription occurs, then translation.  First the photocopy is made of the instruction manual pages, and any junk edited out= transcription.  Then the instructions are read and the protein assembled=translation. These processes go together.  Look on the options on the left side of the webpages under 3-D animations.  There are lots more there, too!
