Each student needs:

• Explosion at Chernobyl Reading
• Pollution Points Information Sheet (copy on back side of Explosion at Chernobyl Reading)
• World Map Worksheet for plotting data points

For the entire class to share:

• Colored pencils — a different color for each day — and to number the points. (Or, if students do this as a group, use sticky dots/stickers to mark the map, 1 per city per group.)
• World maps, atlases, globes, etc., for reference
