It is wonderful to have a first year teacher start using the Learning Center. Here is something that it can offer that will help you find LOTS of already gathered resources over topics that you are teaching.
Start by going to the TAB: "Learning Resources and Opportunities" (at the top of the screen),
then find "Advanced Search (on the left hand side of the screen), type in the Keyword: "Small groups in Science" and Type of Learning Resource: "User Created Collections", then hit "Search".
You have now found LOTS of resources, pages and pages of collections. Not all of these collections will be what you want...try page 2, "Science Learning Center Workstation Collection" by LaToya Pugh. There were several items that I think will be something you can use.
Using different topics to search for in the Keyword, you can then select the grade levels, type of resource, or type of collection that you want. It saves lots of time and introduces you to many resources that you may not even be aware of. I Love this "Advanced Search" option to find resources on the topics that I want to teach.
