Emek and Luna walked through the forest toward their picnic spot. They found a big pinecone and a smaller pinecone. The big pinecone felt lighter than a small, heavy stone. Nearby, they found another stone that was bigger but lighter than the first stone. Their basket was getting heavy, so they compared the objects carefully. They kept the two lighter objects and left the heavier stone beside the path. Now the basket was easier to carry.
