A parody poem for your enjoyment:

If

(with apologies to Rudyard Kipling)

If you can keep your head when all about you

Are losing theirs and blaming it on the teacher;

If you can trust the teacher’s faith in you,

When you are doubting yourself;

If you can work and not be too tired by working,

And do the work because it helps you learn,

And not because it will be graded.

Or because it is required;


If you can dream of success on the test- and not make those dreams your master;

If you can think-and not give up because you don’t know something;

If you can meet hard tests and independent projects with triumph and disaster

And treat those two results just the same;

If you can hear that biology truths are messy and not always true,

That thinking biology is merely facts and terms is a trap for fools,

And the teacher’s job is not to supply truths

But to challenge your mind and help you develop tools;


If you can make a judgment based on all your understandings

And risk it on one answer to an unfamiliar question,

And get it wrong but learn from that

And feel satisfied that you did;

If you can force yourself to take ownership of your learning

To truly learn long after you’ve been accepted into college,

And so not give up when there is nothing in it for you

Except the Will to develop more sophisticated understanding;


If you can talk to your class and help everyone learn,

Or ask questions of wonder or confusion or ‘possiblies’;

If you can recall your learning from last year or last week

And apply it to new situations and grow new synapses;

If you can believe that deeply understanding 70% of the concepts

Is better than knowing 100% of the terms;

If can believe that you own your learning in class and out

And tutors or looking up answers will not help on tests;

Yours is deeper understanding of biology and all that’s in it,

And-which is more-you’ll be an AP Scholar my student!

What we're up to...

Welcome to my AP Bio web site. The material below is from the 2011-2012 school year and I'll be updating it as we implement the new AP Bio curriculum this year. I'll use this page for announcements and thoughts. You can use the links on the side to check out course related materials and some interesting web sites we'll be using throughout the year. Below are links to some assignments and rubrics as well as unit objectives. There are links to many biology resources on the Bio Web page.

I'm very much looking forward to this year. I spent the summer working on developing synthetic biology materials for our use this year. Check out the BioBuilding link to learn more about how I spent my summer.

25. the DNA strands denature

26. the primers bind to the exposed strands

27. The Taq polymerase builds DNA

28. make millions and billions of copies of a small piece of DNA

29. Two enzymes used to build recombinant DNA (DNA from 2 places) are restriction enzymes which cut the DNA at specific sites and create sticky ends - these are used on human insulin gene and plasmid and DNA ligase which seals the 2 DNA's together to form one ring of  rDNA: to induce competence (make host cell bacteria pick up plasmic) add CaCl2 and do a cold- hot- cold shock which makes the membrane more permeable and allows bacteria to pick up plasmid

30. Attach an ampicillin resistant gene to the human insulin gene, ampicillin is an antibiotic which kills normal bacteria, the rDNA will have both and if the bacteria pick up the plasmids, they will be able to grow on ampicillin so..... put the bacteria on a plate of agar (growth nutrients) and ampicillin, if it has a plasmid it will survive and grow a colony, if it does not pick up a plasmid, it will die

31. bacteria that eat oil, drought resistance crops, insect resistant crops, etc.

Carbon: to build organic compounds (carbohydrates, lipids, proteins), CO2, plants take in through stomates in leaves, animals eat food, cellular respiration releases CO2    Nitrogen: to build proteins and DNA, N2 gas, plants take in from soil through roots, animals eat, urinate    Phosphorous: to build DNA and ATP, rocks, plants take in from soil through roots, animals eat food (not rocks), decomposition
