Online labs and activities for environmental science

Posted in environmental science with tags , , , , , , on June 11, 2010 by airtightnoodle

If you teach environmental science or APES (Advanced Placement Environmental Science) you may want to check out the following link:

NROC Environmental Science

The site is designed to be an online APES class and claims to cover all of the material the College Board dictates must be covered for APES.  I haven’t looked through the entire site myself, so I can’t speak for that assertion.  However, there are some neat online labs where students have to change inputs and then assess what happens, and so on.  Check it out.

I failed as a teacher

Posted in Education with tags , , , , , , , on June 9, 2010 by airtightnoodle

Yesterday I visited my local evil government house of mail (a.k.a., the post office).  While waiting in line, I overheard a young boy behind me asking his mom, “But I don’t understand how DNA works.  I don’t get it.”  I glanced back and smiled at him and his mom, impressed that a boy that looked so young would know anything about DNA.  His mother explained patiently that she didn’t know and advised him to ask a science teacher. 

Cue the superhero music!  Science teacher to the rescuuuuue! 

I boldly turned around again with my brightest smile, proclaiming, “I’m a science teacher!” 

The boy, not impressed, asked, “Are you a scientist or a science teacher?”  (At this point I’m sure someone with acute vision could see my ego deflate just a bit.)

“I’m a science teacher.  Is that ok?”

“Well, I guess.  My science teacher really loves science.  She has all sorts of weird stuff in her room.  Like, she loves science.”

“Oh, that’s cool.  How old are you?”

“Nine.”

“Go ahead,” said Mom.  “Ask her your question.”

At this point I was prepared to explain that our bodies are made of lots of teeny tiny cells, and inside each one is a chemical called DNA that tells the cell what to do.  Instead, the question I got was much more specific. “Ok, how does the DNA say if you’re a boy or a girl?  I don’t get it!”

Instantly, since I teach high schoolers, images of sperm cells, egg cells, chromosomes, and so on go tumbling through my mind, and all I can think of is sexual reproduction.  My jaw drops a little bit. 

“Um,” I stutter to Mom, “I’m not sure how to explain that to a 9 year old.”

Creationists in Texas attack the Earth and Space Science standards

Posted in Education, Evolution, Texas with tags , , , , , , , , on January 25, 2009 by airtightnoodle

As if the foolishness surrounding the biology TEKS (Texas Essential Knowledge and Skills) wasn’t enough, the proposed standards for the Earth and Space Science course are under attack as well. 

Steven Schafersman has reported on this issue at his blog on the Houston Chronicle’s website here.

Victory in Texas for Science? Not quite…

Posted in Education, Evolution, Texas with tags , , , , , , , , , , on January 24, 2009 by airtightnoodle

Earlier this week the Texas state board of education agreed to strike the phrase “strengths and weaknesses” from the current science standards.  This move was cheered and celebrated by many scientists and teachers all over the state. 

However, on Friday, January 23, the state board looked at the issue again and decided that students should have to evaluate a variety of fossil types and assess the arguments against universal common descent.

On one hand, I feel like saying…ok!  Send me some fossils so I can teach that (hey, I’d love to have more fossils for free in my class).  But of course, it wouldn’t work like that if this proposal gets passed. 

This proposal is completely unscientific and is in the same spirit as the “strengths and weaknesses” clause that was struck down.  What is even more amazing to me, personally, is that at least before this creationists/intelligent designer proponents could make the argument that they weren’t singling out evolution–they wanted to teach the strengths and weaknesses of ALL theories (which of course for the most part wasn’t true, but they could still make that argument).  This new proposal is blatantly singling out evolution. 

Not surprisingly, chairman Don McLeroy, a self-proclaimed creationist, also added the following:

Also added to the proposed standards by board Chairman Don McLeroy, R-Bryan, is an amendment that directs science teachers and students to “describe the sufficiency or insufficiency of common ancestry to explain the sudden appearance, stasis and sequential nature of groups in the fossil record.”

Board member Barbara Cargill had a lot to say as well.  Recall that I recently contacted Ms. Cargill asking her to explain some of her recent comments in an editorial from a Texas newspaper.  She has never responded.

One board member who pushed for the change said that fossil records create scientific evidence against universal common descent — and students should be allowed to study the possibility.

“There are many, many gaps that don’t link species changing and evolving into another species, so we want our students to get all of the science, and we want them to have great, open discussions and learning to respect each other’s opinions,” said Barbara Cargill, R-The Woodlands, a former science teacher.

She scoffed at claims that social conservatives on the 15-member board were just trying to find another way to expose students to creationism — the belief that life, Earth and the universe were created by a supreme being.

“This isn’t about religion. I don’t know how many times we have to say it before people accept it,” she said. “It’s about science. We want to stick to the science.”

As usual, Ms. Cargill seems to assume that teachers who WANT  to teach evolution properly are trying to censor their students’ thoughts and opinions.  Of course a good teacher wants students to be able to ask questions and respect others’ opinions.  However, this move is certainly about religion.  It’s not about science, because what these board members are proposing to teach students isn’t backed by the scientific community.

There is still hope, however.  The board will not take a final vote on these newly proposed science standards until March.

Take action to support science in Texas!

Posted in Education, Evolution, Texas with tags , , , , , , , , , , , on January 20, 2009 by airtightnoodle

From the Texas Freedom Network:

This Wednesday the State Board of Education will hear public testimony on proposed science curriculum standards. The new draft standards reject efforts by creationists to undermine instruction on evolution. They also make it clear that supernatural explanations like creationism/”intelligent design” have no place in public school science classes. But creationists who control the state board are insisting that the standards require students to learn phony “weaknesses” of evolution. They want to force publishers to include those bogus arguments in new biology textbooks.

Take Action!

Help us turn back efforts to sabotage the education of Texas schoolchildren by standing up for science this week!SUFS

  • Click here to sign up to testify before the State Board of Education IN SUPPORT OF THE DRAFT STANDARDS at the public hearing on Wednesday. The board will hear only four hours of testimony. But even if you don’t get a chance to speak, adding your name in support of the draft standards is very important. Also, supporters of the draft standards will WEAR GREEN at the hearing to show their support for a sound science education.
  • Tell your state board member that you SUPPORT the draft science standards and OPPOSE efforts to water down the curriculum by opening the door to phony attacks against evolution. Click here to find the name and contact information for your State Board of Education member. Once you have the name of your board member, you can also click here to send an e-mail to him or her in care of the Texas Education Agency.
  • Donate to the Texas Freedom Networks’ Stand Up for Science campaign. Your contribution will help ensure that the next generation of Texas schoolchildren gets a 21st-century science education that helps them succeed in college and the jobs of the future.

 

Texas science education update

As mentioned on my blog already, the first draft of science TEKS has been posted online.  Now you can share your comments on the TEKS. 

The comment forms for the first draft of the proposed Science TEKS have been posted at http://www.tea.state.tx.us/teks/scienceTEKS.html.

The Science TEKS Review Committees will meet at the end of October and begin reviewing comments.

The end of October is here.  So go read the TEKS and post your comments NOW!
