I love this one from Tom Barrett
“Use a combination of Twitter and Google Earth as a unique mapping activity or intro to using Google Earth.
- Ask your Twitter network for challenges, GeoTweets if you will. Do this in advance of the session to give people time to respond.
- Guide the children quietly – you want them to be explorers not tourists!
- Encourage the children to found out about the area of the GeoTweet – find proof – we found the name of the local garage for one!
- Tweet back the proof to the sender to say you have found them. Maybe ask a further question about the area.
