These are just some of the beautiful murals adorn the outside of the labs at Schmahl Science headquarters.

Let’s say you’re a student who wants to do a biology experiment for a science fair. Maybe you want to figure out how a certain cancer works or engineer a drought-resistant plant or any other sort of higher level experiment. How in the world do you get started and then do the necessary experiments?

If you know a biologist, then you can get them to help you. Unfortunately most folks don’t know any scientists let alone biologists. What interested people usually have to do is start cold-calling institutions and universities, hoping to find someone willing to help. This is rarely successful.

But if you’re in the South Bay, there is another possibility – Schmahl Science. For around $40/hour, you can do your experiment with the help of a mentor in the lab facilities at Schmahl Science headquarters.

The price is a bargain by science standards but still ain’t cheap. For example, a cancer project can end up costing upwards of $3000! There are scholarships available and there is a sliding scale based on family income, but it will still definitely cost you. However, if you’re interested in doing a top notch science fair project and learning more about science as a career, you can’t beat it.

I recently had the chance to take a tour of the facilities and chat with the executive director, Belinda Schmahl. My first impression of the place was that it was a bit ramshackle. It seemed to have been cobbled together from various spare parts into a Frankenstein sort of creation. This is because it was.

They are able to keep prices so low (and really, they are low) by using other people’s castoffs in a location that is a bit off the beaten track. What it lacks in finish, though, it more than makes up for in personnel.

I was incredibly impressed with the mentors I spoke with. They were knowledgeable and very excited about their students’ projects. And I can see why.

One student I saw there was working on a biochemical experiment to test how well various sunscreens actually protect people from harmful ultraviolet light. One mentor told me about a successful experiment a student had done to generate electricity from bay mudflats. Another mentor told me about a student’s project that was exploring how houseflies were able to fly. Still another told me about a student’s project on the effects of the herbicide RoundUp on certain bacteria rice needs to grow. And so on.

Of the 100 students mentored for the Synopsys science fair last year, 78 received some sort of award. This gives you some idea as to the quality of the work and the guidance each student receives.

These are incredibly interesting and important experiments that the students would not be able to do on their own. What a great service this organization provides for the community. I hope one day it can be cloned over and over again so more students can experience the thrill and excitement of science.

Water and cornstarch make a non-Newtonian fluid when mixed: messy but great fun!

Fast-forward fifteen years to the beginning of the present school year and the Internet has given us all a huge leg-up in finding hands-on ways to learn science. These are demonstrations rather than experiments–an important difference for those entering a fair. Nevertheless, I have included two of my favorites below.

Homemade Oobleck:

Pay tribute to Dr. Seuss's book Bartholomew and the Oobleck by whipping up this mixture that is both solid and liquid at the same time! The simplest version is listed below, but adding a few more bells and whistles can increase the demonstration's awe-factor a bunch.

What to do: You need a mixing bowl, water, and cornstarch. Fill the mixing bowl with about 1 cup of cornstarch, and add roughly an equal volume of water. Mix, incrementally adding cornstarch or water until the mixture attains an appropriate blend of goopiness and firmness. Enjoy the fluid's bizarre properties by squishing and kneading it with your hands.

What's going on? Nearly all fluids have some intrinsic flow resistance. This property, called viscosity, is the reason water flows more easily than honey and at least partly why Usain Bolt can run 100 meters in under 10 seconds while it takes Michael Phelps well over a minute to swim the same distance. Our water/cornstarch mixture has a very special viscosity, making it easy to dip your hand into the mixture slowly, but quite hard to push it in quickly. (Technically, this is an example of a non-Newtonian fluid.) Science class will teach you that almost all matter can be classified into either a solid, liquid, or gas, but this is at least one example where the distinctions blur.

Bernoulli's Hair Dryer:

In 1738 the mathematician Daniel Bernoulli (pronounced Ber-NEW-lee) published a theory of fluids that has influenced the designs of airplane wings and sailboats ever since. Exploit this concept to suspend a balloon or ping-pong ball precariously in mid-air with a hair dryer.

What to do: You need a hair dryer and a small round balloon (or a ping-pong ball, depending on the hair dryer's strength). Turn the hair dryer on, point it upward, and place the balloon in the vertical column of air. If the ceiling is not too high, you should be able to balance the balloon in mid-air this way. Now begin to tilt the hair dryer and watch the balloon stay suspended almost magically.

What's going on? Everyday experience helps us understand why the balloon or ball stays suspended when the hair dryer is pointed vertically: air blowing upward pushes on the balloon, and this in turn counteracts gravity. But why doesn't the balloon fall off to the side when we begin to tilt the hair dryer? The answer lies in Bernoulli's principle, which states that, all other things being equal, a fluid loses pressure as it picks up speed. The air coming out of the hair dryer is moving faster than the room's air so its pressure is lower. This pressure difference helps keep the balloon suspended, even when you tilt the hair dryer.

School groups tour the Oakland Schools Science Fair
projects at Chabot. Ben Burress, Chabot Space & Science Center

The science projects of students from a range of schools in Oakland are on display at Chabot Space & Science Center for a couple of days-a long-time tradition I know, because when I was in elementary school (Glenview Elementary in Oakland) I participated in the Science Fair every year and wound up with my First Grade project (Which Straw Works Best-longer or shorter?) on display at Chabot Observatory on Mountain Blvd.

So I went out into our halls to browse the rows of free-standing cardboard displays (all pre-fabbed display boards; in my day we'd make our own from boxes, staples, and glue!) to see what today's young minds are thinking about science. In particular, I was looking for any that dealt with astronomy.

As usual, I saw a range of science topics, presentations styles, decoration, and grade levels. I saw the cadre of "standard" science projects that get done every year (the tabletop volcano, the floating egg, the electric potato, and the like).

I also saw some that I'd not seen before. There was one where the question asked was who has more germs, boys or girls? The experimenter took swab samples from behind the ears and from the hands of the students in her fourth grade class and grew germ cultures, which were all displayed before the presentation board in little plastic Petri dishes. What was the result? Do you want to know? Well, by this experiment at least, the girls won over the boys in having more germs from both sample sites….

But what of the astronomy? In all of the couple hundred project displays, only three of them were astronomy projects. This doesn't surprise me too much, since astronomy is for the most part an observational, not experimental, science and doesn't lend itself to the kinds of things kids like to get their hands into. And of my own elementary school science fair projects, not one of them dealt with astronomy, so I really can't complain!

What were they? One dealt with observations of Moon phases, asking the question is there a pattern to the way in which the Moon's shape changes from day to day. One asked why do the planets of the Solar System take different periods of time to orbit the Sun, and why do they have different temperatures. Finally, one asked the ultimate Inconvenient Truth sort of question: What would happen to Earth if the Sun suddenly turned off? (That would be inconvenient!) The answer to that one was, not long, since just about everything we do requires energy derived ultimately from the Sun.

The results of my own observation project, walking down the halls of Chabot and seeing what's up in the minds of our youth, was a happy success: the curiosity and scientific enthusiasm of our budding scientists appears to be alive and well.
