In this download there is one student worksheet provided with three different websites for students to research the different aspects about homeostasis. Answer Key is included.
This works very well for a period in the computer lab, or if your school has technology such as tablets, netbooks, etc, then the students can type in the link or scan the QR codes to direct them to the link. It can also be used as homework if you are trying to get students to research more information while still providing them the sources to go to.
So once you printed out the student pages, instruct the students to open up tabs for each of the different websites and that the words on their page is identical to the words on the websites.
I use this as a way to trick my students to reading more about homeostasis. If they are searching for the answers, then they are also having to read the passages as well.
