Hands-on science: chemicals required

Cover of a 1950s-era chemistry set, as featured in an EDN blog by Paul Rako.
Do you know a child who is the proud possessor of a science kit? As much as you may love the idea of kids playing with science, maybe you shouldn’t feel too excited for them. As Paul Rako noted in a recent  EDN blog (“When kids really had fun with science”), today’s kits are not what they used to be. For example, one of the illustrations in his blog shows a newer chemistry kit proclaiming that it contains “no chemicals”!

Actually, after reading in Paul’s blog and his reader’s comments about what one could do with 1950s-era kits, it’s clear that while today’s kits have less potential for pyrotechnics and high-voltage excitement, that might be a good thing in some ways.

But it also brings to mind some comments made last summer by Marc Nantel, Associate Vice President of Niagara Research at Niagara College Canada, a Senior Member of SPIE, the international society for optics and photonics, and Chair of the Society's Education Committee. Marc is dedicated to advancing photonics R&D, and also very dedicated to advancing photonics education and STEM education (science, technology, engineering, and mathematics) in general.

He is one of many educators who have become concerned about studies suggesting that the next generation is developing with inadequate skills in science and mathematics.

Marc noted that the fact that it is harder for young people to get a hands-on understanding of electronics these days doesn’t help. For example, he said, think of the old-style television or radio set. When it wasn’t working, you could take the back off and check the tubes or the wiring, and often figure out what needed fixing -- and then fix it, learning something about electronics in the process. You can’t do that with your new high-definition TV or your smartphone, not without already having the right diagnostic equipment and proper training.

So the chemistry kit may not come with chemicals, and a curious youngster can’t learn about electronics these days by taking them apart. Nonetheless, Paul Rako’s readers’ comments offered some interesting ideas about how to learn about science, with varying levels of hazard and ingenuity.

How did you explore science as a child? What sort of homegrown opportunities do today’s kids to have fun with science these days?

Ten Ways to Celebrate the first International Day of Light

The first International Day of Light (IDL) is less than a month away. A global initiative highlighting the importance of light and light-based technologies, communities around the world are planning events celebrating IDL on 16 May. First Place Winner of the 2017 SPIE IDL Photo Contest SPIE will participate in outreach events local to our community in Bellingham, Washington, attend the inauguration in Paris, France, and host an IDL reception for our conference attendees at SPIE Optical Systems Design in Frankfurt, Germany taking place May 14-17. SPIE is also supporting local events in 13 different communities from the US to India, Canada to South Africa, who were awarded SPIE IDL Micro Grants to create activities that highlight the critical role light plays in our daily lives. Do you need some ideas on how to show your appreciation of light on the 16th? Here is our top ten list of ways you can celebrate IDL 2018: 1. Throw a Celebration:  Light up your party with light an

#FacesofPhotonics: NASA Intern Elaine Stewart

MIRROR, MIRROR: Elaine with the JWST at Goddard Space  Flight Center in Greenbelt, Maryland Meet Elaine Stewart: chemical engineering student, world-traveler, intern at NASA's Goddard Space Flight Center, and this week's SPIE Face of Photonics. Elaine is fascinated by space exploration and how optics impacts our ability to "study distant stars that have never been seen before." Her research has taken her around the world -- from Bochum, Germany, where she studied material science and engineering at Ruhr-Universität, to Houston, Texas, to work on the James Webb Space Telescope (JWST) while it was under cryogenic vacuum chamber testing, to Melbourne, Australia, where she studied biochemical and product engineering at the University of Melbourne in 2017. And, when she's not busy traversing the globe, she is focusing on graduating from the University of Delaware in 2019 with a Bachelor's in Chemical Engineering. Elaine makes a point of remaining an active

Taking a Deep Dive into the World of Biophotonics

Gavrielle presents her research in Ven SPIE Student Member Gavrielle Untracht is pursuing her PhD at The University of Western Australia. She had the chance to participate in the 9th International Graduate Summer School in Biophotonics this past June on the island of Ven between Sweden and Denmark. At the school, sponsored by SPIE, invited experts from around the globe gave extended presentations on topics like tissue optics, strategies for cancer treatment using lasers, and entrepreneurship in photonics. Attendees also had the opportunity to present their current research projects, results, or ideas. Gavrielle shares her experiences of the summer school with this community in the following guest blog post. I recently returned from a week of great discussions and beautiful weather at the 9th Biophotonics Summer School on the Isle of Ven, Sweden. This experience, made possible (in part) by SPIE, was an invaluable opportunity for networking and a deep dive into the world of bi
