Clean a slide and heat it in the blue portion o the fame. 2. While the slide is still hot, mark with a china marking pencil as shown. 3. Place a loopul o organism on the right side o the slide. 4. Tilt the slide so that the organism fows down over the surace o the slide 5. Completely air-dry the slide. (DO NOT APPLY HEAT!!) 6.
