Hello! Here are all my elementary STEM lessons and other resources for grades K-5. I decided to offer all my elementary STEM resources for free as I wasn't making much on TPT anyway and would rather have teachers have free access and use the resources.
You will find NGSS lessons by grade level and also lesson folders that marked Other lessons. The Other folders might have lessons that fit your state or counrtry's standards.as well.
Also visit my website, www.stemiselementary.com, for other resources and a free monthly elementary STEM newsletter.
Feedback is very helpful. Let me know if you are looking for a lesson that fits a particular topic.
