Hey guys, just wondering if someone could help me out in how to vary the temp in my firsthand invesigation assignment..to decrease temp im putting sample in a fridge and the control is going to be just at room temperature...anyone got any ideas to increase the temp? ive thought about using lights and all that but its just too power consuming and the like....what did you guys do for it?

depends what it is, you can heat with bunsen burner, put in incubator, put in hot water bath, etc

also for coolong you can put it in a ice bath, etc
