Science unit: What do plants and animals need to survive?

In science this fall we've been studying what plants and animals need to survive. We are investigating a fictional school whose garden no longer has any monarch butterflies living there, and using this story as a way to learn about plant parts, habitats, and how plants and animals survive. We've been on an observation walk, grown garlic with and without water, analyzed several types of plants that did and didn't grow, and planted radish seeds. Below are some pictures from our investigations as well as our models of how plants get the water they need!
