It's cold outside and the options to do anything that involve leaving your warm home seem limited at best. But with school delays and closings piling up we wanted to provide a fun STEM activity to keep everyone hopefully occupied and entertained.
One advantage that SUPER cold temperatures have is that they provide an opportunity to create FROZEN BUBBLES! If you're little one created their own "super strength" bubble solution with us then now is a great time to get it out and explore the STEM around bubbles even further. However, if your little one didn't create bubble solution with us there is no need to worry as any store bought bubble solution should suit.
The skin of a bubble is actually made up of three layers (see image) and when temperatures drop (we mean really drop like into the single digits and below) the water layer can begin to freeze!
For the best chance at creating Elsa grade bubbles we'd suggest blowing the bubble and then gently catching them on the wand. As our temperatures may not dip below zero degrees Fahrenheit the bubbles need a little bit of time to sit for the water layer to crystalize.
Have your camera at the ready and see if you can capture some awesome frozen bubble images and share them with us at https://www.facebook.com/RosieRiveters or https://twitter.com/ARosieRiveter using #RRBubbles.
We hope that you enjoyed your first proper snow days of the year! As this year's forecasts have us braced for quite a bit more snow (perhaps even this Sunday!) we wanted to share a couple of fun STEM snow activities to keep your little ones busy.
We know eating snow is a debated topic (more info on that here), but if your family decides that eating a little snow is ok with you then here is a fun recipe for Snow Cream. Take some tome to observe the physical changes, melt rate and general snow consistency along the way:
- Mix together
- 1 cup of whole milk or cream
- 1/2 cup of maple syrup (or sugar although it may be a little grainy)
- 1 teaspoon real vanilla extract
- Pinch of sea salt
Add the mixture above to
- 8 cups of fresh (CLEAN!) snow. You can even set your collection bowl out when the snow starts to fall to capture the freshest snow.
- Mix until the mixture forms an ice cream like consistency. Eat and Enjoy!
The science of chemistry is the study of matter and the chemical changes that matter undergoes. Explore Chemistry by combining different substances to try to form snow. Make sure to observe the properties of the substances before and after combining them.
- Baking Soda
- Sodium Bicarbonate
- Glitter (Optional)
- Pipet/ Eye Dropper (Optional)
- Mix equal parts of baking soda and sodium bicarbonate together in a container. Add glitter if desired.
- Use the pipet (or just pour a little bit) to add vinegar to the snow mixture
Whats Happening? When baking soda and shaving cream are mixed together they form a number of new substances including but not limited to sodium stearate, carbon dioxide and water. What makes the snow cold is the process of the liquid in the shaving cream evaporating. The reaction from the vinegar touching the baking soda creates bubbles that release carbon dioxide which is what creates the fizzy look.
Rosie Riveters is honored to have partnered with Microsoft to develop and deliver a coding project during our February-March 2016 pilot program and to work with the many experienced, dedicated and enthusiastic Microsoft women who gave their time as volunteers and mentors for our programs. Rosie Riveters is constantly working to expose our participants to tangible, relatable, and real experiences that encourage girls to not only better understand STEM as a field, but also see possibilities for themselves as future engineers, computer programmers, and scientists. So when Microsoft invited our participants to the Microsoft Technology Center (MTC) in Reston,VA we enthusiastically said yes!
School’s out and summer is finally here!
But did you know that students lose an average of one to two months of academic knowledge—primarily of science and math—over the summer holiday?
Although the books and calculators have been put away until the fall, summer opens the door to one of the best classrooms for science, technology, engineering, and math (STEM)—the great outdoors. It also affords parents the opportunity to be a part of their child’s learning experience while enjoying quality family time. Here are a few fun (and budget friendly!) ways to incorporate STEM in common summer activities:
Do you know a college student (or very motivated/capable high schooler) that is interested in learning the ins and outs of content development and data analytics in social media?
“I grew up in a very big family in a very small house,” says Lydia Villa-Komaroff. That house was in Santa Fe, New Mexico, where few Mexican-American kids like herself were lucky to even finish high school. But Villa-Komaroff knew from a young age that she wanted to become a scientist. She remembers when she was nine, hearing her uncle talking about his work as a chemist and deciding that this sounded like the career for her. “All children are scientists, but… I think it gets lost because people forget about the excitement and the joy of discovery,” she says. “I wanted to continue to explore things, take them apart, put them back together.”
Woman inventor rises above financial trouble, pursues her dream, garners nearly thirty patents and revolutionizes an industry. Sounds like a modern-day success story. Even though Helen Blanchard would be remarkable by modern-day metrics, the fact that she achieved all of this during the late nineteenth century is even more impressive.
Katherine Freese is the Director of one of the most prestigious theoretical institutes in the world, Nordita, the Nordic Institute for Theoretical Physics, in Stockholm, Sweden. During her three year placement the institute is serving as her base for pondering the deepest mysteries in the cosmos, in particular the identity of dark matter, which makes up most of the mass in the universe but has stubbornly refused to reveal itself in physicists’ searches.
