My Little Gems: Preschool Ideas for Teaching Plants (& Sprouting Seeds). A great take home kit idea. Simple materials and the students will be able to grow the plant right inside the bag! I like this for a home/school project.
Life Cycle Articles in two versions (two-page with photos and one page with just text), QR Codes for additional research via web sites and videos, and Fact Sheets useful for sorting. These are perfect for my second and third grade students.
