Trundle wheels are great for measuring long distances of 1 to 500 meters or
more depending upon how patient you are and how far you are willing to walk.

watersheds, and the interactions around specific habitat studies, such as pond or
stream studies. In addition, by constructing contour maps, students will develop
a more thorough understanding of and ability to read topographic maps.
Making Underwater Viewers
Underwater viewers are useful in observing organisms under water, as well as
the characteristics of the bottom of ponds, lakes, streams, and tidal pools.
