Have to teach the timeline of Space Exploration???
In this activity students receive 1-3 cards with important events in astronomical exploration history to illustrate. Once all are 'prettied up' have students share the events in timeline order (starting in BC) and hang them along a wall in the classroom! This has proven to be a fun and engaging way to go through these important events! Timeline events go through 2012.
You can cater this to different levels by choosing only certain events to include.
