Week of June1-4
Both Chemistry and Biology work on practice regents, June 03 due on Monday the 7th.

2004-05-27T07:39:00.000-07:00

All science sections are in review mode.
Biology has just completed its first practice regents which we will go over in class.
Short test on Friday in Biology: topics include environmental issues and ecology.

Chemistry is working on practice regents.

Students should organize all materials; notes, study guides, books, etc and study each and every night... Finals are around the corner.

2004-05-24T08:23:00.000-07:00

May 24th
All sections are working on practice regents, the plan is to have your first practice regents complete by Wednesday.

IMPORTANT Bio students; Check out the DNA link: we have expanded our blog and now have the first animated lessons concerning DNA... Want to really know DNA.. Check it out! The first of two new lessons are posted... Super animation!!

2004-05-21T11:07:00.000-07:00

May 21: No Homework over the weekend.. Have a great weekend.

Parents: Have your student check out the great regents review links that are offered at through our site. Just check the side bar.

Chemistry Notes for 5/10-5/12

Conjugate base pairs and titration are the main topics

Sample: Conjugate base pairs: HNO3 + H2O - H3O+ + NO3- determine conjugae base pairs:

HNO3 and NO3- : H2O and H3)+ are conjugate pairs

Titration problems use MV=MV formula, you are given 3 knowns and one unknown in which to determine the solution to the problem.

H30+ is called a hydrated proton and is known as the Hydronuim ion.

Biology Notes for 5/10 -5/12

We have looked at types of symbiotic relationships between organisms: Mutualism, commensalism, and parasitism.

Predator prey population interactions

Students need to know that communities make up ecosystems that in turns make up biomes that make up the biosphere that make up they ecosphere.

All major biomes should be studied: desert, deciduous forest, taiga, tundra, rain forest, marine, freshwater

Lecture notes
Biology watched HHMI videos on genetics and microbes and took a test.

Chemistry Worked on redox review and conservation of charge with respect to 1/2 reaction.
Ex: Mn +4 + 2 e- = Mn 2+
We did extensive redox review on Thursday and ALL CLASSES took a test on FRIDAY...

4/26 notes: M. Oberkircher we hope you are enjoying South America: STUDY redox
Bio: Mutagenic agents: radiation, cosmic rays, chemicals can cause changes to genetic makup of an organism which can result in diversity. Sometimes positive, sometimes negative

Chemistry: Conservation of charge within a reaction ex Li = Li+ + 1 e-
NOT: Li + 1e- = Li+ treat the eqn as a math statement.

redox equations contain a reducing agent and an oxidizing agent

What ever is reduced is the oxidizing agent
What ever is oxidized is the reducing agent

Determine this in the following :
Li + Na+ = Li+ + Na

Reduced=Na+ is also the oxidizing agent
Oxidized= Li is also the reducing agent

Monday 4/19
Biology notes on Transcription and Translation, mRNA copies code (3 letters=codon) goes to ribosome where translation takes place with the help of tRNA. this is where amino acids are joined to make a protein.

Congratulations to color guard on a great showing: Extra Credit if you check this while out in California... and tell me when you get back. Have Fun

4/6 Notes:

Biology
Chromosomal mutations: deletions, tangling, flipping, breakage; these occur when?? most during meiosis. We began molecular genetics with replication of DNA which is selfconserving: a little old and a little new.

Chemistry

completed organic chem with a review, began redox with a defininition of what redox is
Reduction gain electrons, oxidation number decreases as you gain electrons. Think about this!
Oxidation lose electrons, oxidation number increases.
NOT all reactions are redox, only reactions where electrons are gained and lost by species within the reaction.

Biology 4/5
Notes on How to determine blood types A and B are co dominant, We used I's to develop punnet square, see page 422 of text book for more information
Environmental effects on gene expression: see page 407 of text book for more detail.

Chem notes;
Organic reactions: Saponification: soap making: has both hydrophyllic and hydrophobic ends
And many monomers make a polymer: organic examples; starch, proteins, Dna Inorganic examples: plastics

Biology notes
Morgan discoverers genes exist in chromsomes
studies fruit flys
finds that they have 3 autosomes and 1 pair sex chromosomes
finds that more males are white eyed than females
proposes sex linkage of some traits
Which chromosome carries sex linked traits such as hemophilia, color blindness or cystic fibrosis???
The X chromosome does... Males are the affected ones.

Chemistry notes for 3/31
decscribed Isomers.. same formula but different structure, we found that this can only occur with hydrocarbons longer than 3 carbons.. meaning 4 or more can form an isomer.

Know saturated hydrocarbons and unsaturated hydrocarbons
sat=all single bonds
unsat= double or triple bonds present

this is important for answering questions dealing with two reactions : addition and substitution
saturated cannot do addition reactions; no room but you can sub
un sat can do addition until filled then can only sub

Label and draw
aldehyhde R-CHO
ether R-O-R, Di ethyl, methyl. propyl ether... Review functional groups derived from the alkanes
Esterfication: join an organic acid and an alcohol ( in this order) Condensation synthesis ( you knew this in biology as dehydration synthesis.

In lab we are making esters.

So we have gone through all of the functional groups with the exception of the amide group

Lectures will now move towards organic reactions
substitution, addition, polymerization, esterfication, saponification, cracking
