Now that they have discussed energy, air, water, and soil, first and second grade Biomes are discussing life on Earth, including both plants and animals. They have explored this through several manipulatives. The Second Great Lesson is a presentation that follows life from the first microscopic life to the plants and animals we see on Earth today. Students built the Timeline of Life, which explores the emergence and extinction of life over time. This week they have been building the Tree of Life, which is a graphic representation of modern life. The branches help students visualize how different species are connected.
