Interactive activities on "Nature and environment" topic for pupils of 9-11th grades!

And also I’d like to recommend a website “National Library of Medicine. ENVIRONMENTAL HEALTH STUDENT PORTAL” with interactive activities on “Nature and environment” topic for children of 9-11^th grades. So, there are 4 subjects: air pollution, chemicals, climate change and water pollution. I think that is the best website, containing a lot of educational, well-compound and interesting games! There you can also find links to presentations, some videos and even experiments!

Try it and have a nice day! 

Games and exrcises!
