Leave It To Ari - Elinor, Olive and Ari are helping Ari's dad rake the leaves in their yard, which leads them to wonder, "Who rakes the leaves in the forest?" They need more observations, so they head out to the forest, where they look at the leaves more closely and notice that some of them are fresh, others are a little worn, and others are really old and crumbling. The kids also notice some of the dirt on the ground has little bits of leaves in it, and they realize that the leaves that fall on the forest floor eventually get old and go back into the soil, just like the compost that Ari's Dad makes. Snow Friend - Elinor, Ari and Olive are building a giant Snow Friend, but there isn't enough snow to finish their masterpiece. Luckily, the next day brings fresh new snow, but this snow won't stay packed at all - it just falls apart. After they go in the house to warm up, they observe some snow melt and get sticky, and they figure out a solution - warm up the snow! When they put their plan into action, the warm snow has just the right stickiness for packing. Just in time to build a super Snow Friend. Hurrah!
