Gara Villalba came into Room 5 to teach a lesson that will be applied to our learning during our Yosemite field trip. Students acted out the sun, carbon, and the Earth to learn about climate change and its alarming effects on ecosystems around the world. In the Park, we will be taking a close look at bark beetles’ exponential growth and why they are causing tree mortality. Students took notes as she presented and we will be following up with a research assignment tomorrow morning.
