What is CABS?

This site will help high school students and teachers find original, independent science research topics and questions that can be done without a professional lab...these can be done in a school lab or even in one's basement! The project ideas and research questions being developed and presented here have been vetted and could lead to true discoveries, and not just finding already known results. See our Welcome message. These are the types of projects that could be done and submitted to high school contests such as the Regeneron Science Talent Search, Junior Science and Humanities Symposium, or the Regeneron International Science and Engineering Fair, and be competitive. If you have an idea to share, or a question about one of the project ideas, contact us at vondracekm@eths202.org.

Pages (on the right side of the screen) have lists of ideas for different types of science research projects, and clicking on one of those ideas will take you to posts with details and all sorts of information about that type of project. Get more information about why there is a need for CABS!

Student Research Publishing Options

With the unfortunate circumstances of COVID-19, all student events and competitions around the country have been cancelled, including the International Science and Engineering Fair, or ISEF. Many students who have done wonderful research and qualified at their regional and state fairs will not have the chance to present their work. Those students may want to consider trying to publish their papers in some of the following student journals, listed below. 

Of course, for students who work in university labs, if you get good results, your professor may very well want to publish. Students can and have be first or second author on such papers, and this is a rarity for high school students - it is worth asking a professor if results might be publishable.

A third option is for teachers and schools to have a website or page dedicated to posting student reports. This is a good idea so they are at least online, and can be used as good examples of high school work for future students. Here is one example, with dozens of papers from former students (with their permission) that are often used by current students to get ideas, see what research looks like for a high school student, and also are used as a template when a current student is writing up his/her research. 

Students can submit their research papers to the following journals for publication:


  • *Note that many CABS projects can be used by other teachers as lab demos, students labs, or inquiry projects for their students. You might consider writing a paper, co-authored between student and teacher, and submit to teacher professional journals, such as The Physics Teacher or The Science Teacher.

Why the rush to Shut Schools and Large Public Spaces and Events down???

We are in an unprecedented time of shutting many aspects of civilization down around the world, because of the COVID-19 pandemic. But why the rush and urgency???

It is the math and science behind how a disease spreads, which is referred to as exponential growth. Please check out a really well done explanation of what this means, how it works, and how experts use a mathematical model to simulate the spread of a disease. It uses actual data from China to make its point, and you will get the gist of why social distancing and washing hands make such a BIG DIFFERENCE in the number of people who might become infected. For anyone who does math modeling, it also explains sensitivity testing really well.

Please check it out, and gain new appreciation for some of the math you learn in school but might not know how it is applied to the world!

Two hydraulic jumps on an incline

One way professors run their research programs, and as they go from year to year and have new graduate students joining their team while older ones graduate and leave the team, is to have extension on earlier projects and studies. Good research projects are those that have interesting questions studied, but when answers are found there are even more new questions developed because of the study.

Hence, something like hydraulic jump continuously provides new, original research options. For example, one option is to have multiple streams of water forming multiple jumps, that can interfere with each other. Another option is to study jumps on inclined surfaces. But what about combining those studies into one? This is an option a student recently has done, as a preliminary project. Check out the video for some pointers about how ANYONE can do this at a school or at home, and how there are so many more questions that can come from this preliminary one: from the fits of these data, can someone take existing theoretical math models for single jumps and modify it, at least as an empirical formula, to make a math model for interfering jumps? For jumps on an angle, where a component of gravity enters the model? And then for the combination of the two? What about interference patterns one can see in the video for this project? All of those flow details are not yet studied and documented! Numerous more projects can be developed just from this one study. Be creative, explore, ask questions, and the build an experiment to look into your questions - this is science research at its finest!

Check out Ulo Freitas's video for how he did a preliminary study of interfering hydraulic jumps on an incline.

Initial study of interfering dual hydraulic jumps on incline

A good example of an original basement science research project is setting up an apparatus to create and study the interference of two hydraulic jumps on an inclined surface. There was a study done by a student at his house for two interfering hydraulic jumps on a flat surface some years ago at Evanston, but now a student was interested in taking that type of study and tilt the surface through a range of angles. Preliminary results are in a paper the student wrote.

There is an extension that can be done on this experiment. One possibility is to try even larger angles, as well as vary the flow rates of one or both of the jets. For any of these studies, one could also take the best-fit functions of these data and modify existing theoretical equations for jump radii - an empirical formula at the very least could be developed to explain this phenomenon.

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!
