Topographical Maps

Last week we were all about topographical maps.  We started off by looking at a handout on how topographical maps are made and looked at the physical picture of a place and then the topographical map.

Then the fun began.  L made up a tiny mountain range with two peaks.  She trace around it and then I took a piece of string and sliced a layer off the bottom.  She traced her mountain range again.  I kept slicing off layers and she kept tracing them until at the end she had made a topographical map of her mountain range.  We decided that each layer would represent 10meters so at the end L was able to see how tall each peak was.  It was so cool that we tried a few other types of mountains.

Once she had a firm understanding of how a topographical map is made she matched the landforms on this sheet.  L wanted to make one of the landforms so we did the opposite and made layers from one of the topographical maps and put them together.

Yup.  A topographical map of L's hand.  She loved this!
