This worksheet is a great warmup for a chemistry/science class. It is easy to read and doesn't require a lot of discussion beforehand. It can be used in the beginning of the year or anytime during the school year to get students applying their knowledge. I have used it with my intro to science lesson. It has helped my students to understand that science is important not just for school but in their daily lives. This can be done individually or in small groups. There is an options to have them separate into small groups to discuss the impact chemistry has in their lives. This can be optional depending on the time allowed. I find it useful to post the small group lists of life impacts. It can be an eyeopener for some students. You can print out the infograph from the website I have provided or you can just use a projector and project it on a whiteboard.
