Activity
Growing crystals
In this activity, students grow crystals, learn that they are formed when solutions cool and study their characteristics (regular shape and shiny).
New models for volcanoes
Professor Richard Price describes how New Zealand scientists are rewriting the textbooks on how volcanoes are understood. Studying andesite volcanoes, they have discovered that all volcanoes may not form the same way.
