Narrative:

The engine was making normal power and did so from run up until about 45 seconds after takeoff. We had made a left hand turn to practice some touch and goes when the engine RPM reduced along with the egt. Carb heat was applied and the engine slowly began to regain RPM as I continued to head towards a known field and preplanned engine out site during takeoff. As the engine RPM spooled back up I allowed the airspeed to build up and at about 300 ft AGL; I climbed back to 1500 AGL. I went back to the airport and executed 3 normal touch and goes with no issues. Attributed the loss of RPM to carb ice and was glad I had preplanned landing sites in the back of my head during an actual event.
