Science Starts with density and distance

A rousing game of “Will it Float?” occasionally played on The Late Show with David Letterman was really just an impressively popular density guessing game. In our recently added Science Start Outreach Program, Discovering Density, we play a similar game, predicting and testing to see what happens when you toss things into a tank of water. The Science Start program is for grades K-2 and travels to schools, daycares, scout groups, and more to educate students with hands-on learning experiences.

Sahil tests the hypothesis that a tiny metal car is denser than water and will sink.

The most fun results are the ones that surprise the young students, like a whiffle ball that will not sink even though it is full of holes, a Lego brick (you’ll have to test that one out for yourself), or liquids that can float on or sink through other liquids in a density column.

SS1

Carolyn points out to a class at Passmore Elementary that an object that is floating must be touching the surface of the water in a presentation of the new Discovering Density program.

Making the distinction that density isn’t just about weight or mass or size but instead the comparison between the two can be a tricky concept at first. Similarly, very small and very large numbers, distances, and time scales can be difficult to grasp, so to make it a little easier, you could try holding a planet like Jupiter or maybe Neptune, if you prefer, as we model the vast distances of our solar system and think about scale in Space: Going the Distance.

Carolyn points out the different types of liquids forming four distinct layers in the density column that she made during the presentation. The density column was given to the group’s teacher after the show so that students could watch it change over time.

Volunteers spread out with their planets to see the relative spaces between their orbits and explore what a model is, why it’s helpful, and what about the model isn’t quite as it is in real life. For our model to be to scale for both the sizes of the planets and for the distances between them is tricky—in a classroom-sized solar system, it’s going to be almost impossible to see most of the planets from most seats, and even the sun seems petite!

Carolyn holds up a three-foot board that models the planet Jupiter. If Jupiter was just three feet across, the Sun would have to have a diameter of 23 feet!

Girl Scouts earn badges for science at HMNS

by James Talmage, Scout Programs

After more than a year of hard work, Girl Scouts Heidi Tamm, Zoe Kass, Meredith Lytle and her sister Angela Lytle completed the entire Scouts@HMNS Careers in Science instructional series, earning each scout a total of seven badges.

Careers in Science is the Scouts@HMNS series of classes for Girl Scouts that aims to introduce girls to different scientific fields, lets them meet women working in those fields, and shows them what it’s like to work at the museum. There are seven different classes: Archeology, Astronomy, Biology, Chemistry, Fossil Dig, Geology, and Paleontology. As the Fossil Dig class finished up March 7, those four girls added their seventh and final Careers in Science patch to their vests.

Girl Scouts accept badges for completing the Careers in Science series of classes at HMNS. Pictured from left to right are Angela Lyle, Meredith Lyle, James Talmage, Heidi Tamm, and Zoe Kass.

Heidi Tamm and Zoe Kass have been taking the classes together since the summer of 2013.

“They were really into earning all the patches and completing the whole series of classes.” said Julia Tamm, Heidi’s mother.

Heidi, whose favorite class was Archeology, said, “I liked science before the classes, but now I understand about the careers and what people actually do.”

Zoe kept taking the classes because of the fun activities and being able to see the museum in more detail. Her favorite class was Paleontology, which focuses on the Museum’s Morian Hall of Paleontology. 

Meredith and Angela, Girl Scout Cadette and Senior, respectively, have also taken all the classes together. Angela explained that she learned “there are lots of careers in science available and there are lots of women that work in science, especially at the Museum.”

Meredith encouraged other girls to try out the classes, even if they aren’t interested in science.

“You may decide you like it, or you’ll just learn something new,” she said.

The sisters agree that the Girl Scouts organization is moving more toward STEM (Science, Technology, Engineering, and Math) careers, and that it’s not a boy thing to go into science. Anyone can do it, especially Girl Scouts.

Girls Exploring Math and Science 2015

7whgnk0118-L

Last Saturday, we celebrated our 10th year of hosting Girls Exploring Math and Science (GEMS) at HMNS! Despite the questionable weather, we had a spectacular turnout! From underwater robots to photobooths, we had it all.

7whgnk0173-L

The GEMS event includes two sections – community booths and student booths. Our community booths are hosted by local STEM organizations. They present STEM activities or demonstrations to young students and they talk about how they got their STEM careers. This year, the Subsea Tiebeck Foundation brought an exhibit called SEATIGER. It’s a giant tank containing an underwater ROV (Remotely Operated Vehicle) for students to learn about how STEM is involved with the offshore and subsea industries. GEMS also included fault line activities, polymer demonstrations, and astronaut dexterity challenges from some of our other community booths!

In addition, GEMS hosts student booths. As a student booth, students present a project relating to science, technology, engineering or math to peers as well as adults. Every year we award the top three projects with prize money for their school, club or Girl Scout troop. This year we had some exceptional projects! Third place went to Girl Scout Troop 17492 for their project, The Human Battery. Like true scientists, these fourth grade girls had to reconstruct their experiment after their first attempt failed. Luckily, they reconstructed their experiment, and found an alternative way to power a battery using lemons instead! The second place team was another group of Girl Scouts, Troop 126005. Their project, POP! The Power of Programming, examined the intricacies of computer programming and each of the girls designed their own small program too! First place went to Jersey Voltage, the Jersey Village High School Robotics team. The team built a robot that could throw a ball, and they demonstrated their robots talent by playing catch with some GEMS participants! They plan to use their winnings to take their robot to a robotics competition in Texas or Louisiana!

We hope that everyone that joined us at GEMS 2015 had a great time! If you took some photos in our smilebooth, you can see them here!

Join us at GEMS next year on Saturday, February 20, 2016!!

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!
