 BOULDER - The students that walk into Laura Jordan's classroom are the ones that have struggled in school. Many of them are new to this country. Others have already given up on learning.

| The debate over C-sections and VBAC |
 DISCUSS ON MOMSLIKEME.COM
KUSA - Cesarean births are at an all-time high and fewer women who have had a C-section in the past are opting for vaginal births on their next pregnancies. This trend has spurred the National Institutes of Health (NIH) to reassess current recommendations on birthing practices.

sink. Even non-scientists find great joy in dropping stuff in water
to see if it floats or sinks. Fans of David Letterman are quick to
point out one of Dave's favorite segments called "Will It
Float?" Here's the latest float or sink challenge: Why do
lemons float in water but limes sink? Think you know the answer?
Not so quick...</p>

Vista, Colorado asked this question: Would you voluntarily run at a
full sprint headfirst into a brick wall? Now, think of sitting on a
bicycle without a helmet, and then tip over with a little over a
second to intervene before your bare head hits the ground. Which
sounds worse? This question and his amazing research lead Raleigh
Burt to win the 2005 Junior Division Best Individual Science
Project for the State of Colorado. Despite the fact that bicycle
helmets are considered the single best means of protecting cyclists
from the leading causes of head injuries and death, many people
still choose not to wear a helmet. That is the choice many riders
make to become one of the 67,000 cyclists who will suffer a head
injury this year.</p>

If you've ever seen seen an ice skater start to spin slowly on the tip of their skate and then speed up into an incredible blur of a spin, the secret is pure science. The best part is that you don't have to be on the ice to test out the science behind the spin. Find an office chair that spins easily and a few weights and you're ready to make yourself dizzy sick. But it's all in the name of science.</p>Mon, 01 Mar 2010 14:52:35 -0700Ice Skating Spinhttp://www.stevespanglerscience.com/experiment/ice-skating-spinLeprechaun Secrets Revealedhttp://www.stevespanglerscience.com/experiment/st-patricks-day-sciencehttp://www.stevespanglerscience.com/content/science-video/leprechaun-secrets-revealedThe mysteries of Leprechauns have been discovered!Liven up the holiday with a little green science!<p>Don't confuse green science with Irish green science. We never miss an opportunity to teach a little science... even on St. Patrick's Day. From Leprechaun traps, to green water, to Leprechaun eggs, we know how to celebrate St. Patrick's Day at the Spangler Science offices... and trust that none of us will ever forget the day the toilet and faucet water turned green. Sometimes your creativity spikes and you find gold (pun intended) when you wrap your mind around a specific theme. So, here are some of our favorite tips and tricks for infusing a little science and a lot of fun into St. Patrick's Day.</p>Mon, 22 Feb 2010 09:01:16 -0700Leprechaun Secrets Revealedhttp://www.stevespanglerscience.com/experiment/st-patricks-day-scienceFire Tornadoeshttp://www.stevespanglerscience.com/experiment/fire-tornadohttp://www.stevespanglerscience.com/content/science-video/fire-tornadoes Steve reveals the dangers fire tornadoes have on our environment.A fire tornado or fire whirl is just like a tornado but made of fire. <p>When you picture a tornado, most of us imagine a whirling column
of air poking down from the clouds. But this tornado-like effect is
not limited to just the air. A fire tornado or fire whirl is just
like a tornado but it's made of fire. As the heated air from
the fire rises, strong air currents (often whipping through the
trees) cause the air molecules to spin (often referred to as
angular or rotational momentum) which shapes the flame into the
shape of a tornado.</p>

It's just a
little puff of air trapped in a thin film of soap and water, but
its precise spherical shape and beautiful, swirling colors make it
a true wonder of science. A bubble's life expectancy is usually
measured in seconds unless you know how to make a SUPER BUBBLE!</p>

All of the nails have to be balanced at the same time and cannot touch anything but the top of the nail that is stuck in the base. If you're really ambitious, you can try your luck at our large-scale version using landscape nails and a friend as the base. Enough of this idle chatter... get balancing!</p>Mon, 18 Jan 2010 20:14:00 -0700Balancing Nailshttp://www.stevespanglerscience.com/experiment/00000083Tea Bag Rocket - Convection Currentshttp://www.stevespanglerscience.com/experiment/tea-bag-rockethttp://www.stevespanglerscience.com/content/science-video/tea-bag-rocket-convection-currentsThe science of hot air and convectionA great after dinner science stunt using a tea bag and matchesThe Tea Bag Rocket is really an adaptation of a classic science demonstration called the Ditto Paper Rocket. If you're old enough to have experienced Ditto paper, you'll recall the bluish-purple ink and that unforgettable smell of freshly printed copies. (Come to find out... both the Ditto machine solvent and the ink were highly toxic, but no one seemed to care back then.) Each piece of Ditto paper had a sheet of tissue paper that separated the two-part form, and it was this discarded piece of paper that kids used to make the "rocket." Since Ditto paper is a thing of the past, science teachers found a simple replacement - a tea bag.
