Here are some short videos produced by NPR about the history of germs. Watch one, two, or all three of these videos and we will discuss the history in class. Here are some listening tips:
1) Watch first without subtitles. Focus on your listening. For more ideas about listening, watch this video from AJ Hoge.
2) Don't try to understand every word. Just the main ideas. Try to answer the questions. We will discuss the rest in class!
3) Repeat! Watching the same video a few times is better than watching new ones.
