I learned about Planet Impact from TechLearning. It’s a series of engaging online activities where students can learn about comets and their affect on planets.
It’s presented in relatively simple English that’s accessible to Intermediate English Language Learners. There are several games students can plan, including ones where they calculate angles to determine if their comet will hit or miss planets.
I’ve placed the link both on my Science page and my English Themes For Beginners page under Planets and Space.
Just wanted to say that I went to your Geography page and found it interesting and informative. I teach Geography to the 6th and 7th grade and 7th has North and South America. Since this is the first year that I am teaching 7th, I am having to do a lot of research. thanks for providing so much of info.
