Grade 2: Interdependent Relationships in Ecosystems
2-LS2-1: Plan and conduct an investigation to determine if plants need sunlight and water to grow
To introduce my students to the study of plants, I project the first 8 pages of this packet onto my classroom whiteboard. Each depicts a full color illustration of a plant along with an interesting fact to facilitate class discussion and to capture the children’s interest! Then we discuss parts of the plant using the student worksheet included in this packet. The next worksheet is for analyzing the veins in leaves and figuring out what they do. Students do a leaf rubbing using crayons. Then we do a "chlorophyll rubbing" of leaves - the green pigment that captures sunlight in the photosynthesis process transfers onto paper- such a fun activity! We then set up 3 experiments using 3 plants where we change the water and the sunlight that each plant receives. 3 student follow up worksheets provided: Do Plants Need Water? Do Plants Need Sunlight? What Do Plants Need?
If you do not have plants in the classroom or if you would just like to reinforce concepts, I’ve included 4 slides showing plants under different conditions of water and sunlight. 2 student worksheets go along with the slides: Gnome Flowers (reinforces the fact that plants need water) and Flowers and Sunlight (reinforces the fact that plants need sunlight). Answer keys provided.
If you do have access to dirt, cups, and seeds - I've included a Plant Journal to keep track of growth (see photo above). Marigolds are my favorite plant for my little ones to grow!
To wrap up this unit, we create mini-booklets entitled, “What is Photosynthesis?” This explains photosynthesis in child-friendly terms in a coloring book format. The mini-booklet is 6 pages but only requires 2 sheets of paper per student, pages are copied on both sides.
