On the engineering side, Rocketry a possible option

For those students and teacher who look for engineering challenges, don't forget about rocketry. This is a huge hobbyist field, and there are so many commercial kits and sets one can purchase (many smaller rockets can be purchased for under $100, for instance). And there are also so many videos available on YouTube and other rocketry sites to get ideas for building your own.

Learn about structures and the stresses they undergo on a launch, the chemistry of rocket fuels and motors, the areas of physics called aerodynamics and fluid mechanics, electronics if you want Arduino or Raspberry pi based sensors in the rocket, and so on. This could be a nice way to build interest among larger groups of students and just start with purchased kits; learn from the kits, and let students begin to make their own designs and test them. Just something to consider if there is an interest.

At the college level, many engineering colleges and universities will have rocketry clubs. Check out USC's rocket, the first to have an all-student group build, from scratch, a rocket that surpassed the Karman line, which is the established boundary something needs to cross to be considered in space.

Check out this article and video of a rhenium molecule moving around two carbon nanotubes. You can see the two atoms move far apart, when the bond breaks, and then re-bonds back into the molecule. VERY COOL!! This is but another example of incredible electron microscopy techniques that your generation has available, and who knows what remains to be invented and discovered with such instruments. While this is outside the realm of 'basement science,' it never hurts to see what is out there as high school students, so you can have some sense of what awaits you should you pursue STEM in college and beyond!

Top 10 Science Discoveries of the 2010s Decade

An interesting list of Live Science's Top 10 scientific discoveries for the 2010s, from the Higgs boson to gravitational waves, and synthetic life to exoplanets in habitable zones and new CRISPR techniques, have fun reading and seeing videos on these game-changing discoveries. We cannot even imagine what discoveries await today's teenage, future scientists!!

Generating electricity from potential differences of natural systems: Rivers meeting Oceans

The notion of "blue energy" is intriguing. What this means is using the coastal regions where rivers of freshwater meet oceans or seas that are salt water. With special filters/membranes, one can use this mixing area of nonionized water with ionized salt water to separate electric charges - effectively making a battery, from which electricity is the result. Because so much of the world's population lives on or within miles of coastlines, there is great interest in this as of now untapped electrical energy. The trick will be to make these membranes on a massive, cost-effective manner; presently these are too expensive for companies to try and scale up to industrial sizes.

While we won't be able to build large power plants in a high school, great projects for those interested in electricity, electrical engineering or electrochemistry would be to try to identify and create 'batteries' with any combination of materials you can find that will allow for a potential (i.e. voltage) difference. Are there other natural systems we could tap into to generate even small amounts of electrical power? Interfaces between different types of soil, minerals, plants, or other? There could be some really interesting, but unknown, combinations out there that could surprise us!

Think about this, be curious, explore and investigate!! Take a multimeter/voltmeter outside and look for combinations to test!

Good example of the science process in action: Large black hole

Astronomers have recently discovered a really large stellar black hole (meaning a star died and turned into a black hole). This black hole has a mass some 70 times the mass of the sun. The trouble is, according to current theories of star formation and deaths, a stellar black hole of this type should not exist - it is too massive according to our best understanding of stars.

So, either our best understanding is not good enough yet since we have something that does exist that is outside those theories, or perhaps the measurements are wrong and we are calculating too big a value for the mass. Or there could even be a little bit of an issue with both the theories and measurements, although this is the least likely possibility.

Whatever the case, this is a wonderful example of how science works! Nature often throws us curveballs that are outside of our best models and theories, and scientists need to sit back, rethink things, and figure out what is wrong with the theoretical understanding of the topic or what new information needs to be added to a model or theory. Scientists must be humble enough to accept we do not know everything, but the whole point of what we do is to learn and grow and gain better understanding of our crazy, fascinating universe! Below is the now famous first photo taken of any type of black hole (this is a supermassive type, at the center of a galaxy)!

Online course, ideas, and summer program for Space Biology

Carthage College in Wisconsin has put a course for space biology online for anyone to use. This is a rare chance for high school students and teachers to begin learning about this exciting, relatively new field, and also get ideas for experiments and techniques used in the field. Check it out if interested!

Also, there is a high school summer camp (4 weeks in California) some may be interested so they can learn about space biology and other aspects of that work NASA is involved in.

If interested in plants and botany, get some ideas from this: improving photosynthesis

We face many challenges in the future when one considers population growth, human migrations from coastal regions, and climate change. It is estimated we will need to produce about 60% more food by 2050 to feed the 10 billion people who will be living on earth.

Photosynthesis turns out to be inefficient, and if scientists can figure out how to make plants better at producing more food per plant, that will literally help to feed the world. Check out what some scientists are doing to improve the photosynthetic process of plants. Can you get any ideas of things you can try to improve the food yield of certain plants? New ways of growing and farming plants? Be creative, get inspiration and motivation from what some of the professional scientists are doing, and try your ideas! In science, one never knows what the 'right' idea is until it is tried and tested - just talk with a teacher or other adviser and go for it!!
