[We] aborted first takeoff due to a slow airspeed indication after a long takeoff roll. I thought the student (5 hours total time) was dragging the brakes. We taxied for a second takeoff. I took the controls to perform a short field procedure. I held the brakes; applied full throttle and noted the proper static rpm and engine indications. After a normal length ground roll; I pitched for climb out attitude; shortly after noticing airspeed indication of 40 KTS. I lowered the pitch attitude to maintain a safe airspeed indication and noted only 200 FT per minute and decreasing climb rate. I notified Air Traffic Control and circled from the takeoff runway to land on closest runway at an altitude of approximately 300 FT above ground level. The engine seemed to be operating properly throughout; but I decided to maintain a safe airspeed indication to prevent a stall at low altitude. I circled to non-active runway due to low altitude; with closest safe touchdown point.
The instructor and student pilot of a Cessna 152 aborted takeoff due to a slow airspeed indication. Following a taxi-back; the instructor assumed the controls for another takeoff. After a normal length takeoff roll; he pitched to a normal climb attitude then noticed the airspeed indicator at 40 KTS. He lowered the nose and returned to ensure a safe airspeed and returned to the field; landing on the closest runway.
