The first one is about windmills. He did this one on Friday and really enjoyed it. We are also going to make a windmill this week. A good link for that is http://www.creative-science.org.uk/paperwindmills.html.
The next worksheet is about the canals of Amsterdam. We did this one with the second chapter of Hans Brinker because it talks about the children skating on the canals. A couple of good links to go with this worksheet are:

The last worksheet is about ice skating which is popular in the Netherlands but I made it mostly to go with Hans Brinker.

That's all I have so far but then again we are only on the third chapter so I am sure there will be more in the future. We are really loving Hans Brinker and the Netherlands so far.
