Use roots as meaning clues, then test them in real context.
Root Discovery Map
Six root families. Twelve target words.
bio = life
biodegradable - able to be broken down naturally by living organisms
biosphere - the regions of Earth where life exists
viv/vit = life
vitalize - to give energy or life to
vivid - producing strong, clear impressions
eco = house, environment
ecosystem - a community of organisms interacting with their environment
ecology - the study of relationships among organisms and environments
terr = earth, land
terrestrial - relating to the Earth or land
terrain - a stretch of land with particular physical features
aqua = water
aquatic - living or growing in water
aquifer - an underground layer that holds water
flor = flower
flourish - to grow or develop successfully
