termite cannot digest the wood it eats
termite cannot digest the wood it eats. The stomachs of termite workers are filled with little one-called creatures called protozoans. The termite chews the wood and swallows the tiny chips. The protozoans feed on the cellulose in the wood and convert it into foods that both the protozoans and the termite live on.
10
Workers These are the termites that cause most of the damage by eating wood, but they also maintain the colony, build and repair the nest, forage for food, and help care for the young. Workers are the most numerous of the three castes.
11
Workers forage for food; tend eggs, young and reproductives; and build tubes.
They are the most numerous and most easily recognized termites. They are creamy white, have neither eyes or wings, and are only 1/4 inch or less long. Workers need a high humidity to survive

Scientific Method Lab Exercise Exploring Termite Behavior
Materials 6 pens (2 red, 2 blue, and 2 black Papermate & Bic brand pens) White paper Small brush Termites in a Petri dish Termite Trails
15
Procedure 1. Read subterranean termites information and scientific method information 2. Using the pens, draw lines on white paper. 3. Place several termites on the paper gently using the brush to keep them from straying. 4. Observe the termites carefully and write down all observations. 5. Develop several hypotheses based on your observations. Write your ideas one notebook paper per group 6. Develop a procedure so you can test one of your hypotheses. 7. Write the steps in your procedure, and have Mrs. Wilson approve them before starting the experiment.
