I am happy as an educator that you are looking to invest, the point is to start early and start young. Now, it is important to equip yourself with the necessary knowledge of investing. Books by Robert Kiyosaki are great ways to start. In addition, investopedia have a wealth of information.  Personally, I would Google search top ten ways to invest your money before using investopedia to support my research. 

Based on my experience, I would divide investments into safe and high risk. 
Of course, dividend, blue chip stocks and properties are the safest. They are not without risk, but in general, they retain their value over time with some interests given to you. 

As you are young, do consider more high risk stocks such as Aggresive high risk stocks as well as cryptocurrencies. I believe cryptocurrencies are great ways to invest your money. I personally made 5 times the profit for Verge. In other words, do your research, put some into safe investments and others into high risk. Never be greedy and take your time. All the best!

Don't ask for s fish. Ask for the knowledge to get yourself a fish..

If you truly want to invest, you have to first understand what you're getting yourself into and what you want to get out of it. Learn about investments, the what, how and why.. before deciding where to put your money..

Also as you mentioned that you're a Student (underage i suppose?), it means a variety of investment mechanism are unavailable until you are legally of age. (be extra careful of "investments" that doesnt have proper KYC).

Now that is just "regular" investments, funds, stock options, commodity, etc..

Cryptocurrencies on the other hand, i'd suggest you not even put your money near it until you don't have to ask "where can i invest". Learn more about it first before committing your money.

If you are a student i will advice you to invest in skill acquisition and what i mean by that is as a student you should focus more on investing in 

risk-free investments because i know you must have went through alot to be able to save that

money for yourself and still save alot of money and begin to invest on investments that will be more profitable for you...
