Invasion!
In this activity students evaluate the advantages and disadvantages of using biological control to halt the invasion of common ragweed, Ambrosia artemisiifolia. This is an invasive plant which is spreading across Europe. Because of illness caused by its allergenic pollen and competition with crops, it costs Europe billions of euros a year. The solution may lie with releasing non-native beetles.
Curriculum links include:
Ecosystems, interdependence, competition, development of scientific thinking: explain everyday and technological applications of science; evaluate associated personal, social, economic and environmental implications; and make decisions based on the evaluation of evidence and arguments.
