•I squeeze some muscles to make myself long•Then I grip with my little hairs•And use other muscles to pull my behind along

Worm Breath Through Their Skin!

•Worms do not have lungs but I breathe through my skin.•I take in oxygen through my skin and it goes right into my bloodstream. •My skin must stay wet in order for me to breath, but if I am in too much water I will drown.

Worms Like the Dark

•I can tell the difference between light and dark . . . pretty good for someone who does not have eyes.•I have cells in the front part of my body that are sensitive to light.

Worms Eat Without Teeth!

•As I eat my food some grains of sand and soil get into my gizzard.•The sand and soil grind the food into tiny pieces

Worm are Good for the Garden•Worms help to increase

the amount of air and water that gets into the soil.

• They break down organic matter, like leaves and grass into things that plants can use.

•When they eat, they leave behind castings that are a very valuable type of fertilizer.

Worm Composting•The worms are kept in a bin with shredded wet paper.

•You feed them food waste. •They digest the waste and bedding then make worm poo

•After a few months, the poo combined with the well-decomposed bedding, becomes garden food
