Digesting Sunshine

This Saturday morning at 10:00am, Born to Do Science presents... Dr. Rob Burnap, a microbiologist at Oklahoma State University, who will share with us his research on photosynthesis.

So you think you know photosynthesis? We all learn about it in grade school, right? It's easy to get the impression that photosynthesis is all figured out. If that's the case, why aren't we efficiently using the sun's energy to run our world, just like plants do? It turns out there's a lot more to know and Dr. Burnap is one of the many scientists around the world who research this important topic!

We are planning wall-to-wall demonstrations and activities on Saturday to help you understand why photosynthesis is so complex, amazing, and tough to untangle. Please join us at the Stillwater Public Library! The program is designed for kids in 3rd-7th grade and their adults to enjoy together. See you there!!

Photos from the lab:

Green algae are a convenient species to use to study photosynthesis. It is also hoped that we can eventually use algae to produce clean fuel for transportation on a commercial scale.

This equipment measures the Oxygen output from photosynthesis to an incredible degree of accuracy. Such data can be used to better understand how photosynthesis works.

Here is Dr. Burnap, looking a bit green. He often has to work under green lighting in the lab. Can you think why that would be? Be sure and ask on Saturday!

Brain Science This Saturday!!

Howdy, Science Fans!

Our next BTDS program is about studying the brain! How does your brain work?? You might know that it's separated into two halves - the left brain and the right brain, and that the two halves generally specialize in different types of thinking. The two halves are connected by a thick cord of neurons called the corpus callosum.

Most of what we know about which half does what we've figured out from brains that aren't functioning normally. For example if a person's brain is injured and they lose the ability to speak, then we know that the part of the brain that was injured must have something to do with speaking. Studies on people whose corpa callosa has been severed (for other reasons) can tell us a lot about how the left brain functions without the right and how the right brain functions without the left.

But it's a lot harder to find out anything about how the brain works when it's whole and healthy and functioning properly. We can't just watch it do its thing! How and when and why do the two halves "talk" to one another? What does each half contribute when they are working properly together?

Our guest scientist this month has an ingenious way of studying these aspects of our brains!

Dr. Shelia Kennison is a psychologist who uses glitches in language as windows into how our brains function. By carefully studying how people make meaning out of written words, she can reveal communication between the two sides of the brain!

We will get to experience what it's like to be one of Dr. Kennison's subjects, and as always we'll get to "think like a scientist" and explore other ways the mysterious workings of the brain might be understood.

The program starts Saturday morning at 10:00 at the Stillwater Public Library, room 119.
I hope to see you there!!

Popular Teens This Saturday

Dr. Lara Mayeux

Howdy Friends!

You do not want to miss our next Born to Do Science program, because it's all about you! This Saturday the 17th, 10:00 am at the Stillwater Public Library: "Popular Teens, Friendly or Mean?"

Our guest scientist is coming all the way from Norman. She is Dr. Lara Mayeux, a developmental psychologist from the department of psychology at OU.

Dr. Mayeux will speak about her research on social status among teens. We'll discuss a study she ran following students from 5th through 9th grades to determine what kinds of kids become popular.

Her research explores many questions, including: Is there a difference between being popular and being well-liked? What are the benefits and risks to being popular? How do teens' social status change over time? What role does aggression play in gaining and keeping popularity? Does all this work differently for boys than it does for girls?

We'll be asking what methods Dr. Mayeux uses to study teens, and what further questions might she explore. We'll take a survey similar to the kind used in actual research, and with Dr. Mayeux's guidance we'll design our own research on teenage popularity.

As always, I'll kick things off with a brand new song, and I've been having a lot of fun writing this one. It's called "I Wanna Be Popular!"

Please register with the library if you plan to come. Even if you've registered before - they want to know how many to expect. The program is open to kids in 3rd-7th grade and their adults. It's a rare opportunity to enjoy something with your tween-ager! We hope to see you there!

For more information about Dr. Mayeux you can check out her blog: Mayeux Research: Conversations about Peer Relations, Popularity, Developmental Psychology, and Aggression.

Pieces of Protons - Coming Saturday 11/19/11

The proton-accelerating tube underground
at the Large Hadron Collider (LHC)

Howdy friends! I've been looking forward to this coming Saturday's program for a long time! Here is the official description, then I'll tell you more about why I'm so excited...

Ramping Up the World's Greatest Physics Experiment

Dr. Flera Rizatdinova from the Oklahoma State University Department of Physics will speak about her work on the ATLAS detector at CERN's Large Hadron Collider. The ATLAS is a marvel of technology built to explore dark matter, gravity, the standard model, and other deep mysteries of the universe!

We will be talking about the fundamental building blocks of the universe! Did you know that everything you see and feel around you is basically made out of super tiny particles called quarks and electrons? Those are two of the fundamental particles that make up our Standard Model of the universe. 

Dr. Rizatdinova was kind enough to drive all the way to Texas and back to pick up a piece of equipment called a cloud chamber that detects other fundamental particles called muons. Muons are similar to electrons. They are generated by cosmic rays and they are zipping around us all the time - we just can't see them. 

But when they zip through the cloud chamber - we will see their trails!

That's one reason I'm so excited. Another is that the ATLAS detector and the Large Hadron Collider (LHC) are FAMOUS!! If you listen to any science news then you will hear them mentioned a lot.

The ATLAS is like a gigantic microscope, for looking at the tiniest things! And it's the world's largest physics experiment! 

There are several new things physicists might discover with the ATLAS. One of them is the famed Higg's Boson, which is the last missing piece in our Standard Model of the universe. If they find it, we'll have a complete understanding of how the universe is put together. If they don't, then our Standard Model is wrong, and we'll have to come up with a new one to explain how things work. 

Either way is exciting! And the Higg's could literally be discovered any day now. So we are witnessing history in the making!

I've been studying particle physics to get ready for this program, and let me tell you, it's weird! If you don't understand everything on Saturday, don't feel bad. Even the physicists who study this stuff don't really quite understand it. But that's what makes it so much fun!

If you want to prepare for Saturday, here are some websites to visit. In fact PLEASE visit these sites and learn all you can! I think you'll enjoy them...

CERN

The Particle Adventure

Have fun exploring and I'll see you Saturday, 10:00 AM at the Stillwater Public Library!

The Intrepid White-Footed Mouse

Coming this Saturday, October 15!

The Intrepid White-footed Mouse

How Toxic Waste Affects Animal Populations and Diversity

Dr. Karen McBee, Curator of Vertebrates with the Department of Zoology at Oklahoma State University, will speak about her research into what makes some animal species more resilient than others at the Tar Creek Superfund Site.

Here's a view of Picher, OK from the air - all those white blotches are mounds of chat left over from 100 years of lead and zinc mining! During our program you'll get to think like a scientist and help design a study to try and understand how area wildlife is affected by this.

See you Saturday!

Dr. Karen McBee

The White-Footed Mouse

These voucher specimens are a research tool that allows biologists to compare populations in the wild with animals from different times and places.

The mammal collection is getting a new home! The mice were still packed away when I visited, but Dr. McBee will bring some samples for us to look at on Saturday.

This was one huge armadillo - see the pen by its tail? That gives you an idea of its size!
