This USGS website describes the water cycle and global water distribution. This is a great site to use to brush up on the water cycle processes and where Earth's water exists.
In this experience, a “double circle” with an outer circle facing “inside” and an inner circle facing “outside” provides an interactive space for NatureBridge students to briefly exchange answers to a range of questions about each other’s preferences...
Students will try strategies to safeguard their “nests” from predators and learn the importance food, water, shelter, and space in this active game. This activity is very similar to Jays and Juncos, but debriefed differently.
Students will be involved in an active simulation of populations in this activity. By becoming part of the “ecosystem,” students can see how populations of different organisms change over time, and in relation to each other.
This activity shows the relationship between a predator (jay) and prey (junco) as students play a fun active game. The students will understand how one population affects another.
