You probably think this is a no brainer.
DUH people will swim faster in water, because syrup is thick. But the real answer is SUPER SURPRISING.
Science put things to the test to this “simple” question.
Sixteen volunteers took turns swimming in water and then a syrupy mixture.
Their times were thoroughly compared and, there was no difference between the speeds in the water versus the syrup. How can that be?
The explanation seems to lie in the fact that, while syrup does provide more resistance for the swimmers to overcome, it also helps them generate more forward momentum by pushing against the thicker liquid.

Well, here are just a few things:
Okay, so that’s a lot of awesome right there. But what about this:
Plus, they have some pretty amazing defense mechanisms, from changing color to blend in with their surroundings (or let you know they are angry):
To squeezing themselves into impossibly tiny places. (Did we mention they have no skeleton?)
And a bonus fact: octopuses live in almost all of our national marine sanctuaries!

This is an easy one to try at home with the #kids: make your own homopolar motor. It is driven by the Lorentz force - the force which is exerted by a magnetic field on a moving electric charge. When a battery is placed on top of a magnet, and a wire then connects the top of the battery back down to the magnet, the circuit is complete.
Exploring Potential and Kinetic Energy
During a physics unit, have students explore potential and kinetic energy with these five fun experiments that encourage problem solving and play.

Growing up, Rachel Ignotofsky (@rachelignotofsky) knew she was going to become either a scientist or an illustrator. The Missouri resident chose art, but now she’s combining her two passions with a series of drawings celebrating groundbreaking and often unheralded women in science.
“I wanted to do my part and celebrate these women and their accomplishments and hopefully get a younger audience familiar with them,” Rachel says. “I think that a good way to fight gender bias is to show young girls and boys strong female role models.”
So far, she’s done seven drawings out of a planned 50, highlighting women such as 19th century paleontologist Mary Anning and pioneering computer scientist Grace Hopper.
“A lot of these women are not very well known, even though their accomplishments have changed our world forever,” she says. “I want my illustrations to help spark an interest in learning more about these women. I want young girls and boys to see that no matter who they are, despite their gender, they can accomplish anything.”
Rub your hands on the handles of a Chinese resonance bowl and you can generate a spray of tiny droplets. The key to this, as the name suggests, is vibration. Rubbing the handles vibrates the bowl, causing small oscillations in the bowl’s shape that are too small for us to see. But those vibrations do produce noticeable ripples on the water in the bowl. When you hit the right frequency and amplitude, those vibrations disturb the water enough that the up-and-down vibration at the surface actually ejects water droplets. The vibration of the bowl affects water near the wall most strongly, which is why that part of the bowl has the strongest reaction. It takes even larger amplitude vibrations to get droplets jumping in the middle of the bowl, but you can see that happening in this video of a Tibetan singing bowl.

Quick science experiments.
Hi everyone! I'm Ashley P. and I'm a Girl Scout who wants to make a difference in the world. Currently, I've been working on my Gold Award Project, which is a project where Girl Scouts solve an issue in their community to earn the Gold Award. The Gold Award is the highest award a Girl Scout can achieve. In my project, I'm addressing the issue on how there are a lack of women in the STEM field by creating a program to do fun science experiments with younger girls. Also, I constructed this blog for parents and children to do exciting and simple experiments with their kids to spark a passion in this subject like what happened to me as a child. I hope you enjoy and try to accomplish the experiments I post! Also, please have adult supervision while completing these experiments.
