5th Grade: We have been working learning about weather maps using the internet. Students have been examining maps on www.weather.com. If you have some time at home, have your student show you the website - there are a ton on great features, including videos, a variety of maps, and pictures of current weather events from around the world. A sample weather map is pictured to the right!4th Grade: The 4th graders have been studying erosion and deposition over the last few lessons. We have been using trays of sand to study how water changes landscapes. Last week, we looked at the landforms that result from water erosion (canyons) and this week, we've been looking at the landforms that form from deposition (like deltas). See below for pictures.
Samples of landforms resulting from erosion:
 |
| The Grand Canyon is an amazing example of a landform resulting from erosion on a huge scale. The river, over many years, has washed away rock, leaving behind a deep canyon. |
 |
| The ocean is a source of erosion as well. In this picture, you can see how the water has changed the rocks over many years. |
Below is an example of deposition:

A delta forming where sediments are being "dropped" by the water. |
