You actually don’t have to be a science major to find some of these sites helpful. Many students might have to take a general science requirement in college. As a biology major that takes a lot of classes in one semester, I kind of have a lot of assignments from most classes due in a short amount of time. The sites below I found helpful at one point or another when I needed to get work done fast and/or grasp a concept quickly. Since on exams you can’t use computers, it won’t hurt to actually learn many of conversions or calculations. Though it’s not a huge list, I don’t look to the Internet for all help. Neither should you as I’d hope most of this stuff you’ve learned from your textbooks or professors. I hope some of these sites come as help to those who don’t have all day to be converting units, performing long calculations, and more. The sites below are organized in categories,
Online Converter – This was the most helpful site to me when I was taking physics last semester. This would allow you to quickly do conversions between units or volume, mass, length, work and energy, and more. Heck, it even lets you convert text to Morse code. I doubt I would need that, but hey you never know.
Yahoo Answers – I only used this site for quick answers to problems at the last minute. I never actually post questions on this site. One of the reasons is because you can get caught if you post a homework problem, all it takes is a Google search for your teacher to find out. Just in case I wouldn’t post problems on here. Though, that’s kind of easy for me to say. For my physics class a student from our school posted the exact homework problems and actually got answers from people as well as the calculations needed to solve the problems. Usually, if you have a question then someone else has had that question and they might have asked it on Yahoo Answers.
PDF Search Engine - Need to find an ebook or article then go here. When doing scientific research usually scholarly articles are in PDF form. I actually used this site when I needed to retrieve an article I didn’t have the link to. I just entered in some key words from the title of the article and the PDF popped up. Also, after you search at the bottom of the page theres an option to only search for Word and PowerPoint documents.
Wolfram|Alpha – I haven’t used it yet for any of my classes since it came out this summer. From trying it out it can solve at least basic physics and chemistry problems. Though, it’s important you know how to covert from grams to moles, this does it for you quickly as well as provide the structures of molecules. For biology students you can look up terms and enter in DNA sequences. This is also good for other disciplines like math.
BioStudio – If you’re rusty on simple things like meiosis or lac operon, then these animations are straight to the point. You can go through the flash animations either step by step or watch the whole animation play. There’s also help descriptions of each step in the processes. I would say they’re mostly helpful in general biology, microbiology and genetics.
Purdue: Principles of Biochemistry – School websites are often the best place to look from help. The animations are geared towards those in biochemistry. Basic concepts are here also that may help those in general biology and chemistry.
Smith: Cell Biology Lab – There’s only 5 animations here but they are very important concepts that most if not all biology majors will have to know. Though the site is about cell biology, these animations are important in biochemistry where you’ll also be required to know details for example like, how many ATP are used or and how many carbons are present on a molecule during a certain step. The animations are very straight forward and makes for quick learning.
Biofilms & Biodiversity – This is helpful for those in ecology. Learning how to do calculations for the Shannon’s or Simpson’s index is easy, but the calculations can be time consuming. On this site it gives detail info on how to do the calculations. Though, my teacher explained how to do the calculations in much simpler terms. Anyways, skip the description and scroll to the bottom of the page and you’ll find the calculator!!! It only does 5 samples or species at a time though. It was perfect when my lab partner forgot to do the calculations and we had 5 minutes before our lab report was due!
Microbiology Lab Techniques – Just in case you’re given really generic explanation on how to do certain things then here’s a site that might help you. This page just covers the basics but you can go back to the main page to look at procedures for doing other experiments.
Identification of Unknown Bacteria Application – Probably the most fun part of Microbiology. You’re given unknown sample of bacteria and you have to do dozens of tests on it. Then you guess what the unknown bacteria is. Unfortunately, my lab partners didn’t pay attention to the procedure on using these special kits we were given. Since we had no kit we only could do a few tests on the bacteria. That’s where this application came in. It’s a simple download that doesn’t take up a lot of space. Just enter in the results from your tests (either positive or negative) then it will let you know the possible bacteria that your unknown bacteria could be. Using this application got us the extra credit for guessing the correct bacteria, which is why I recommend this instead of using those flow charts. Just in case you want to use a flow chart or the program is too complication, then go here to Bacterial Identification.
Old Exams & Homework – This is from a schools physics class directory. Now, you can find sites like these by simply doing a little google search. Anyways, this site was most helpful as if you’re a physics student that has to do those annoying WA problems, some of the exact same questions are on the homework assignments on the directory. Also, the most important reason why it’s helpful is because instead of giving the answers there’s actually an explanation showing the calculations used to work out the problems. I would only imagine this site is more helpful to those taking general physics courses.
Work and Energy – Well the title sums it up. If you need quick explanations on work and energy then this is a good site. It’s very straight forward.
Physics Equations Formulas Calculator – haha! Online physics calculators that are simple! Again, you should really know how to solve these problems without these calculators. Just in case you don’t want to pull one of those all nighters doing homework because you procrastinated Anyways, theres calculators from Work to Torque to Hooke’s law and more. Give it a try.
Web Elements Periodic Table – Yeah, periodic table of elements is very important obviously. Just go here and click on an element and get all or most of the info you would need on the element. Elements like O, N, C, H are easy to remember, but who in the hell besides a chemistry nerd would remember the atomic weight of Osmium.
Constants – Here’s all the constants you’ll need in chemistry, nuff said…
Make Asiprin – Usually most Organic Chemistry student will have to make aspirin as it’s a basic procedure. In my organic chemistry class we had to find our own procedure on the web and do it in class. Though, you might want to adjust the numbers to make the amount you’re required to make by your teacher.
Stoichiometry Help – Stoichiometry equals easy. All it is, is basic algebra of unit conversions and balancing equations. But, when first learning stoichiometry, it can look intimidating. This site provides examples and a break down in how to solve the problems.
Chemistry Lab Techniques – Though, you are usually provided instructions to chemistry lab techniques, it never hurts to have an extra site at your disposal just in case. Also, it explains lab techniques in simple forms. Includes the all important procedure of recyrstilization, for some reason a lot of students seem to forget how to do that procedure.
