Earth's Changing Surface: Humans as Agents of Change

Science ObjectDigital resources are stored online in your NSTA Library.

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the last of three Science Objects in the Earth’s Changing Surface SciPack. It explores the natural and human influences on landscape evolution. These influences sometimes accelerate or slow down the process of landscape evolution. Human activities such as deforestation, accelerated global warming, and mining have impacted Earth’s changing surface. These activities are not new processes but often increase or accentuate the natural processes. When natural processes are accelerated, humans are often affected by the changes in their environment.

Wow! The evidence of our impact on the Earth's surface is so strong. I just don't see how anyone could doubt our role in climate change!

I really enjoy Science Objects. In 1-3 hours, the Earth's Changing Surface: Humans as Agents of Change Science Object will help me re-learn, refresh, or learn for the first time some critical science concepts I will have to know to obtain my Science Educator credentials. I appreciate that I can complete them at my own pace, and that, if used as park of a SciPack, I have access to a content expert to go to for help. The NSTA Learning Center Science Objects are really beneficial!

This resource and the ones like it are particularly valuable for me for several reasons. First, I like the table of contents off to the left, which all ow me to keep track of what is coming up and see the entire lesson at once. Also, it is multisensory..enaging several senses. Finally, they are self paced, which I really need with my busy lifestyle.

This is an important lesson for educators of earth science who needs to present the various factors affecting the surface of the earth.

This science object was interesting and gives many examples of how humans can effect climate change.

Excellent, methodic outline for educators that are new or returning to the topics of soil, erosion, and weathering in their teaching. Concise presentation of material, bolded vocabulary that is crucial to student learning..

This Science Object was very descriptive, but I felt that it lacked the "umph" to make the concepts interesting. There wasn't a lot of interaction as in other objects, and the animations weren't interactive as much as videos and illustrations. I did learn a lot from this object, which was great, but I just felt like it took a while to get through because I couldn't get into the material.
