Earthworms

Disappearing Act: Escaping Predation
Data Collection Sheet
(Back to Lesson)

Record your prediction for how long it will take for the worm to go under.
When ready to being, put one earthworm on the surface of each bucket of soil.
Time how long it takes for the worm to disappear below the soil's surface.
Place the worms and soil safely outdoors to return to life as usual.

**How long does it take for a worm to go underground?**
	Prediction	Actual
Worm in Soil type 1
Worm in Soil type 2
Worm in Soil type 3

Now graph your results. You can use your own graphing technique, or simply print out the table below, and then color in the boxes in each column up to the number of seconds it took for your worm to burrow under.
