Hello Katheryn, I so happy to see you use this forum for information. Yes, gathering supplies is difficult. I have used the NSTA Learning Center many times. I especially recommend investigating the magazine "Science and Child" found in the NSTA.org website. Once there, search for the Learning Center. Select "menu", Select "Explore All Resources", Select "Journal Articles & Lessons", select either "View 200 NSTA collestions" OR "View 7,425 User Collections". Just as an example, I chose the tab, "View 7,425 User Collections". Use your "Search" and type in what you are looking for, such as "Natural Selection". You will find 79 choices of articles that deal with "Natural Selection". There are years of artcles with ideas for hands on activities. These articles use the NGSS guidelines and provide you with lists of materials you might need, many of these materials are free and only need to be gathered. Just decide what your topic you wish to investigate, go to the Library and "Search". Good luck with next year!
