Building on knowledge from guided readers in the “My World” series in the A through G levels, this offering in the level H group focuses on food chains and reinforces concepts introduced earlier such as living things, plants, and photosynthesis. It also introduces new words and concepts like energy, chlorophyll, carnivores, herbivores, and omnivores in addition to food chains and food webs. Important words are bolded and defined. While sentences are still fairly simple, there are more sentences per page than the earlier levels.
