The Secret of Life
Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...
NOAA
The Dead Zone
The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.
