Stocks
One of the most common investment types in the world is stock. Stocks represent a share of ownership in a corporation. When you buy stocks, you are essentially a partial owner of a company. Once you buy the stock, you can do with it what you wish, which includes passing it on to your children. It's just like if you started a business and owned it, you have the option of passing it on to your kids. Fisher Investments educational videos talk about this to some degree.
If you are investing with the idea of passing your stock on to your kids, you should look for companies that are poised to be around for the long-term. Companies that have a long track record of success are the best for this. You may also want to look for companies that issue dividends regularly so that you can benefit from the regular income before you pass the stock on to your kids.
Real Estate
Real estate is one of the best investments that you can make right now if you have the idea of passing on something to your kids. As the population continues to increase and more land gets developed, there will eventually be a shortage of available real estate. Look for land that has good potential for future increases in value.
Starting a Business
Starting a business is another good way to have something to pass on to your kids. You can employ them while you are still alive and then eventually pass the company on to your children in your will. You could also give it to them if you decide to retire.
Regardless of what types of investments you choose to put your money into, make sure that you look at them through the lens of longevity. If they continue to grow in value, your kids could have a nice little nest egg by the time they get older.
