How would I go about investing in Light Sweet Crude, Heating Oil, and Natural Gas?

Hi, I see in Investors Business Daily every day the commodities futures charts and there are 3 that interest me. My question is, Do I buy these three items just like stock? Is the closing price listed the price per "unit" on the specific item? Any insight would be greatly appreciated

2. there are ETFs (sold like stocks) that deal with these commodities. They include: DBE, UNG, USO, USL, UHN, GAZ, DBO, OIL, FCG and DUG.
