|Elementary GLOBE Unit: Discoveries at Willow Creek|
In this activity, the GLOBE Kids, on their second visit to Willow Creek, discover why the creek looks different. They learn about making observations, measuring water temperature and speed, and looking for critters in the water. In Activity 1, 'Magnify That', students will be able to identify a magnifying lens and its purpose. They will be able to explain how the same object looks different when using the unaided eye and then using a magnifying lens. In Activity 2, 'Measure Up', students will learn how to make nonstandard and standard linear measurements. They will test their estimates and record their results. In Activity 3, 'Water Wonders', students will have an understanding of what aquatic macroinvertebrates are, what kinds of adaptations they have for their environment, and why scientists study them.
