Lecture – The ABC’s Of Shark Research: Attacks, Biology And Conservation By Glenn Parsons
Wednesday, February 25
6:30 p.m.
Marine biologist Glenn R. Parsons, Ph.D., of Ole Miss will share the findings of his 40 years of researching shark behavior, ecology and physiology in the Gulf of Mexico, which harbors about 65 species of sharks. Sharks here are exposed to both natural stressors including changes in water temperature and oxygen availability and anthropognic stressors that are caused by humans, pollutants and fisheries for example. This lecture is cosponsored by Rice University’s Glasscock School of Continuing Studies.

 

Lecture – Pyramids, Mummies And Cleopatra: Recent Discoveries In Ancient Egypt By Zahi Hawass – SOLD OUT
Saturday, February 28
6:30 p.m.
Chronicling his adventures in archaeology, legendary Egyptologist and archaeologist Dr. Zahi Hawass will introduce the mystery of the Great Pyramids and Sphinx of Giza. He will discuss the discovery of the tombs of the pyramid builders which tells the story of the workmen who were involved in the massive construction projects, as well as the secret doors found inside the Great Pyramid of Khufu. Dr. Hawass will also share his theory on what may yet be uncovered inside the pyramid. One of Dr. Hawass’ recent endeavors has been the Egyptian Mummy Project, which uses modern forensic techniques, including CT scans and DNA analysis, to answer questions about human remains from ancient Egypt. The project has resulted in several crucial findings which he will share with us this evening, including identifications of the mummy of Queen Hatshepsut, new understandings about members of the family of Tutankhamun, and the death of King Tutankhamun. Finally, Dr. Hawass will discuss his current ongoing projects-the search for Queen Nefertiti and the tomb of Cleopatra and Mark Antony.

 

Book Signing – Discovering Tutankhamun: From Howard Carter To DNA By Dr. Zahi Hawass

Sharks are now oversharing…but you will want to follow them!

half-mount2-blogYoung or old, nature lover or couch potato—everyone has some fascination with sharks.

HMNS is bringing in some great opportunities to learn about these predators who have dominated the oceans for millions of years. Leading shark researchers will be at HMNS during the next two weeks to share the latest information on our local sharks in the Gulf of Mexico and the grand-daddy of them all, the great white.

On February 25 marine biologist Dr. Glenn Parsons from Ole Miss will share the findings of his 40-year career of researching shark behavior, ecology and physiology in the Gulf of Mexico, which harbors about 65 species of sharks. Sharks here are exposed to both natural stressors including changes in water temperature and oxygen availability and anthropogenic stressors that are caused by humans, pollutants and fisheries.

Unprecedented research on great white sharks and other large apex predators will be presented by shark researcher Dr. Greg Stunz of the Harte Institute and Texas A&M Corpus Christi with OCEARCH founder and expedition leader Chris Fischer on March 4. In order to protect the species’ future while enhancing public safety and education, researchers with the OCEARCH collaborative are now generating previously unattainable data on the movement, biology and health of great white sharks. The images they will show on the Wortham Giant Screen will be insanely amazing.

Of course you can also get up close and personal with two different shark species at the Museum in the Shark! touch tank experience, where biologists will share shark tales and shark tails.

OCEARCH facilitates unprecedented research by supporting leading researchers and institutions seeking to attain groundbreaking data on the biology and health of sharks, in conjunction with basic research on shark life history and migration.

OCEARCH is a leader in open source research, sharing data in near-real time for free through the Global Shark Tracker, enabling students and the public to learn alongside PhDs. The Landry’s-developed STEM Education Curriculum, based on the Global Shark Tracker and Next Generation Science Standards (NGSS), is being launched for grades 6-8 in the fall of 2013 nationwide.

Over 50 researchers from more than 20 institutions have collaborated with OCEARCH to date with over three dozen research papers in process or completed. Research expeditions are conducted worldwide aboard the M/V OCEARCH, which serves as both a mothership and at-sea laboratory. Utilizing a custom 75,000 lb. capacity hydraulic platform designed to safely lift mature sharks for access by a multi-disciplined research team, up to 12 studies are conducted in approximately 15 minutes on a live mature shark. Powered by five Cat engines, the M/V OCEARCH is capable of Global Circumnavigation.

Here are screenshots showing the favorite hangouts of Wyatt, Sam Houston and Madeline—a few sharks in our neighborhood.

Wonder Women of STEM: Dr. Mae Jemison, the first African-American female astronaut.

Editor’s Note: This post is the fourth in a series featuring influential women from STEM (Science, Technology, Engineering and Math) fields in the lead up to HMNS’ annual GEMS (Girls Exploring Math and Science) event, February 21, 2015. Click here to get involved!

 

We’ve seen some amazing women in STEM, but none are quite so out of this world as Dr. Mae Jemison, the first African-American female astronaut. In 1992, she orbited the earth for over a week on the space shuttle Endeavor and logged over 190 hours in space!

Dr. Jemison had numerous accomplishments in addition to her space travel. She began her college career at age 16 by attending Stanford University on scholarship. Within 4 years, she graduated with a BS in Chemical Engineering and a BA in African and African-American Studies from Stanford University. She continued her studies at Cornell University where she received her doctorate degree in medicine. A few years later, she proceeded to volunteer for over two years with the Peace Corps in Western Africa where she taught health education and contributed to research concerning the Hepatitis B vaccination among others.

After all of her volunteer work, Jemison applied to be part of the NASA Space Program and was one of 15 people selected out of 2000 to join the Space Program in 1987. She joined her first orbiting mission in 1992 with Endeavor. While aboard Endeavor, she worked with other astronauts on bone cell research along with other experiments and investigations. Although her time in space was short, she was able to claim the title of first female African-American in space. In May of 1993, Dr. Jemison left NASA to teach at Dartmouth College and continue to educate future generations.

In addition to her space travels, Dr. Jemison has a list of accomplishments that would knock your socks off. She can speak four languages, wrote her own book called “Find Where the Wind Goes,” was on the cover of JET Magazine, hosted the World of Wonders TV show, and was voted one of the 50 Most Beautiful People according to People Magazine. If that’s not enough, she’s also got a sense of humor. She talks about her experiences in Brazil for the 20th anniversary of the Apollo missions and she comments, “Wow!! Y’all need to be glad I didn’t go to Brazil before NASA or I’d still be there doing development work and the Samba on the beach.” Like I said, impressive!

Space was not the first major accomplishment for Dr. Mae Jemison, and it certainly won’t be her last. She continues to expand interest in science education through her foundation, The Dorothy Jemison Foundation for Excellence. She created The Earth We Share, international science camp for students as well as a program to encourage hands-on, science education through Teachers.

If you are inspired by women such as Dr. Mae Jemison, then you’ll enjoy meeting some of the local ladies of STEM at GEMS this weekend. Come to HMNS between 9 a.m. and 1 p.m. to learn more about science, technology, engineering and math! We’ll even have representatives from NASA!

Educator How-To: Make a Balancing Dipsy!

diplodocusFor those of you who have been going to HMNS for years, you may have noticed that we’ve been missing a rather large lady from our Hall of Paleontology. Our Diplodocus, “Dipsy”, was Houston’s first dinosaur unveiled in 1975 and she was de-installed in September 2013. This was her first trip from home for a well-deserved cleaning. Luckily, she’s due back at HMNS in March! We’re so excited for her to be back that we’ve even put her on our overnight shirts! In honor of her return, we’ve dedicated this month’s Educator How-to to this dynamic Diplodocus.

Dipsy can teach us quite a few things about balance! When we first installed Dispy in 1975, she was a tail dragging dino as you can see in the photo below. With further studies, they realized that large dinosaurs like the Diplodocus couldn’t possibly walk with their tail on the ground. Think of all the friction and weight! Instead, they realized that they must have used their tail as a counterbalance for their long neck and head like you can see in the illustration below. To demonstrate how Dipsy uses balance, we are going to make a balancing Dipsy!

Dispy’s early days at HMNS had her dragging her tail on the ground.

How to make your own Balancing Dipsy:

1. Print a copy of Dipsy on cardstock

2. Color your Dipsy (mine’s going on vacation, so I’ve got her wearing a festive Hawaiian shirt)

3. Cut out your Dipsy along the black lines.

4. If you try to balance her now, you may notice that she’s not very good at it. We need to add weight to correct her center of mass.

5. In this case we are going to use paperclips! Add paperclips to Dipsy to get her to balance. Since she is a very large and currently top-heavy dinosaur, we need to add lots of weight down low to keep her balanced. I’ve added three paperclips per foot.

6. If your students would like more of a challenge, have the students adjust the position of the paperclips and watch as her balancing point changes. See if they can get her to balance using different sized paperclips or changing the location of the paperclips. 

balancing-dipsy

The point on which something balances is in line with its center of mass. The object will be most stable (and easier to balance) if the center of mass is below the balancing point instead of above it. For regularly shaped objects like a rectangular sheet of paper the center of mass is the geometric center of the object, but it depends on the shape of the object and how the weight is distributed (imagine adding a bunch of paperclips to one side of an index card and then balancing it horizontally on a pencil eraser – the center of mass and the balancing point will be closer to one edge now).

For our Balancing Dipsy, the object is an unusual shape and has unusual weight distribution. We needed to add weights to our Balancing Dipsy to make her center of mass below where we place our finger when she is upright. With enough weight we can get Dipsy to balance on our finger or a pencil!

Dipsy is just one of many dinosaurs that use their tails to balance. On your next field trip to HMNS, you can see several dinosaurs in the Morian Hall of Paleontology that have their tails sticking out for balance. See if you can find them all! While you’re here, you can bring your own Balancing Dipsy to see our very Dipsy the Diplodocus. She’ll be back this March!
