The best way to learn about living organisms is to watch their behavior firsthand. Students will use the Nematode Extractors in this kit to collect Nematodes from local soils. Everyone will be amazed to see what they can drive out of the soil samples during a 24-hour period. Organisms will almost magically appear from the dirt. When examined under a microscope, the collected Nematodes will hook your students on the study of life. The plastic extractors are heavy-duty and can be used over and over again. The lab activity requires 24 hours to complete so plan for each class to take turns using the equipment. A microscope is required.
