Three iPhone apps to help you learn science concepts

Do you need a little extra push with your science homework? Perhaps you've waited a bit too long to prepare for that test. Not to worry, these apps can help you review popular science concepts in a flash. The best part is that you'll have fun while you're learning.

ACT Science Flashcards & Exambusters: This app by Exambusters helps students prepare for the science portion of the ACT. It serves as a good overall review of all the science concepts you'll learn in high school. There are hundreds of questions and answers in topics like Earth Science, Geology, Space Science, Biology, Chemistry and Physics. The app features flashcards, 10-question quizzes and a search functionality to find terms and concepts that you need help with quickly. The questions were written by college professors and certified teachers who specialize in exam prep.

Elements – Periodic Table Element Quiz: Elements is a fun, game-like way to quiz yourself on the periodic table of elements. You can play the game one of two ways: match the symbol to its name or match the name to its symbol. There are two levels of difficulty for each of these modes. For more details on the elements, the app has Wikipedia integration. It is a fun yet challenging way to memorize all of the elements of the period table. Unfortunately, you can't select only certain elements to be quizzed on; the app runs through them all. This app is free in iTunes.

Middle School Science 8^th Grade: This free app was designed to help middle school students prepare for the standardized 8^th grade science test, but it's still fun for those of us who left middle school long ago. A monkey flies through space, and to keep him from hitting the asteroids, you must answer the questions correctly. The free version has quiz questions on Astronomy, Geology, Matter and Weather. For 99 cents, you can purchase the quiz pack that covers Biology, Chemistry, Energy, the Experimental Method, the Periodic Table and Physics. Each topic has three levels of difficulty. Teachers can even utilize free reporting tools to see how their students perform on the game. The only negative to this game is the monkey. While it provides a game-like feel, it's not necessary. A quiz app dressed up with a flying monkey is still a quiz app.
