Coalinga High School Earns 6-year WASC Accreditation

Western Association of Schools and CollegesHard work and dedication at Coalinga High School lead to a coveted 6 year accreditation from the Western Association of Schools and Colleges.

According to WASC, this accreditation certifies to the public that Coalinga High School is a trustworthy institution of learning, validates the integrity of our school’s program and student transcripts, and assures the communities of Coalinga and Huron that our high school’s purposes are appropriate and being accomplished through a viable educational program.

Receiving a six year WASC Accreditation was the result of hardworking professionals whose leadership and dedication guided our schools process and kept the focus on the care and education of Coalinga High School students,” said Coalinga High School PrincipaI Margo Perkins.  “I look forward to continuing to work with the Leardership Team and staff to make CHS the best school it can be.



This Wasp Kills Black Widow spiders!

The Blue Mud dauber preys upon Black Widow spiders. Nice!

This is the second metallic green insect that I have found in my backyard over the last few days.  Chalybion californicum is the scientific name of the Blue Mud Dauber. I was lucky to snap a shot of it because they are lightning fast! They range in darkness and in color from blue to green.

Not only do Blue Mud Daubers prey upon Black Widow spiders, but this beauty was kind enough to pause briefly for a photo.  Come back any time little buddy!







Science Daily

Here is one of my favorite website for science articles.


Science Daily is a great website for keeping up on the latest science and finding science related articles. As you have probably experienced, students are not always very experience in evaluating the credibility of internet sources. Some nice features are:
1) All articles are second-source reports published only in reputable, peer-reviewed science journals.
2) The articles are categorized and sub-categorized to easily find topics of interest.
3) At the end of each article is a citation that can be automatically formatted in APA or MLA style.
4) There are a variety of RSS feeds to choose from, such as health, technology, environment, etc…

Match the Molecule

Here are images (DON’T READ THE CAPTIONS YET!) of three important biological macromolecules.

One of them is a nucleic acid.

One of them is a protein (the most abundant protein on Earth!).

One of them is a little bit of both, a ribonuceoprotein.

Can you guess which one is which before you read the captions?

Protein ribbon structure of Rubisco

Rubisco is the nickname of the protein Ribulose-1,5-bisphosphate carboxylase oxygenase

Over the course of evolutionary time, regions of the ribosome in different species have been added while conserving the functional core.

Over the course of evolutionary time, regions of the ribosome in different species have been added while conserving the functional core.

The molecular structure of DNA is like a twisted ladder.

The double helix structure of deoxyribonucleic acid, or DNA, is like a twisted ladder where the sides of the ladder are composed of sugar and phosphate units linked by covalent bonds, and the rungs of the ladder are made of the four nitrogenous bases linked by hydrogen bonds.

Study Reveals Evolution of the Ribosome in New Detail

What good is DNA without a ribosome?  Considering how the ribosome has changed over the last 4 billion years gives insight to the crucial nature of its role in biology, the unity of all life, and the process of evolution.

In the new study, Williams and Research Scientist Anton Petrov compared three-dimensional structures of ribosomes from a variety of species of varying biological complexity, including humans, yeast, bacteria and archaea. The researchers found distinct fingerprints in the ribosomes where new structures were added to the ribosomal surface without altering the pre-existing ribosomal core from the last universal common ancestor.140630164012-large

Adventures in WordPress

Hello World.  Welcome to my new website that is currently being developed using WordPress.  WordPress is open-source software (that means FREE!) that allows website novices like me to build and maintain a full-featured websites with little or no coding knowledge.  I am currently enrolled in a course through The Heritage Institute titled Build Your Website Now! instructed by Michael Boll of  Hopefully this course will lead to a great website for my students and their parents!
