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.
Teach with Trash: Tissue Box Science It would be a good idea to use these as mystery boxes. Place six items in boxes and have them guess what the objects are or what they may all have in common. Could be used to introduce a new unit or book.
